Topic: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

I've got a little Haydn-in-London project going and so find myself using the Broadwood quite a bit these days.  In doing some back-research on the instrument (https://www.youtube.com/watch?v=My1qkV4...e=youtu.be for instance) I was intrigued to find that the physical instrument's action-shifting pedal had two positions: due corde & a true una corda [!].  Now, our normal "soft" pedal is quite fine for the due corde, but what to do about the una corda?  Enter the "Mozart Rail", which happily is available for the whole stable of Pianoteq instruments!    While it's obviously not a perfect simulation of the Broadwood's true una corda, it gets us pretty darn close in its acoustic effect...

so I'll happily eat crow here for having previously been dismissive of the device (well... i'm actually still dismissive of it as rather something of a perverse gimmick when it comes to the big piano, but it certainly has proven useful in our modeling world—viz using it thus on the Broadwood—so that's something i suppose... )

Also, as a side enquiry related to Haydn & ol'Blighty: can anyone point me to an IR for Oxford's Holywell Music Room?  I've been scouring around the net and no joy.  I've of course downloaded most of the freely available IRs and have a few candidates for use in my project, but a ping of the actual space would definitely be the bee's knees.  'am also considering the route of modeling the IR via Voxengo's Impulse Modeler... does anyone have any experience with this program and its generated results?  'worth the time & effort or just stick with real IRs?

cheers,
dj

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

Do you know which Scala file is 'Young's temperament', referred to in the video? There are several files with 'young' in the title. Presumably it's either 'young', 'young1' or 'young2' (the others are different Youngs), but I have no idea which. 'young2' seems to pre-date 'young1', which doesn't make much sense. Haydn's E flat sonata dates from 1794, but the earliest of the Young temperaments is from 1799 (however, this one seems to be the same as Luigi Malerbi's 1794 temperament - so maybe that's the one?)

young2.scl
it dates from c1799 and thus, as a published temperament (Young submitted his paper, "Outlines of Experiments and Inquires Respecting Sound and Light" to the Royal Society in July of 1799, and it was read in January of 1800; see Jorgensen 251), is somewhat anachronistic to Haydn's 2nd London visit (1794-5)... and so i guess Preston's 1785 temperament would probably be a more conservative choice but, as Norris is careful to fudge, Young was likely "working-out" this temperament around the time of Haydn's visit and so, coupled with the sort of writing we get not only from Haydn but also the likes of Clementi, Cramer, & Dussek, makes a lot of sense for the later London School repertoire. 

edit/ps: here's a nice graphic showing Young's 1799 temperament:

indeed! 
though it's perhaps not an entirely unreasonable stretch...
for instance, in his The Virtual Haydn, my old friend opts for Young for his recording of the London sonatas...   
but the proof is in the pudding i suppose, so we'll have to do some more thorough comparative analysis of Preston vs Young in Haydn et al and see what makes the most sense...

edit: as for Malerbi, he apparently was describing something more akin to a Vallotti...?

Yes, agree that the Ptq diagram is very entertaining to watch, at least.

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

more about Holywell Music Room: it's interior dimensions are "21 metres long by 10.01 metre wide (65 x 33 feet). The height is 9.1 metres (30 feet), with the stage platform depth of 4.6 metre. The Concert room's capacity is 200 people seated."  It appears also to consist largely of wood and plaster surfaces.

so I guess any IR that approximates this would work well for my purposes.  I browsed the Altiverb IRs on their website but didn't immediately spy anything... perhaps though someone with the plugin could suggest if there's anything there that might reasonably approximate this?  other suggestions would of course be most welcome.

Maybe this IR could do: http://www.openairlib.net/auralizationd...rsity-york

In the images, the size looks about right although the material differs. I made a little Haydn demo with the Broadwood and the first impulse presented. The soft pedal uses the Mozart Rail. Sounds good to my ears.

Very interesting project!

Yes, I know this room very well, and it's a great historic choice to record Haydn with Broadwood. This is typically the most appropriate acoustics for classical music period.

We had already recreated the IR of the Holywell Music Room in 2016 for an ongoing project, based on the complete Wolf Lieder by Stone Records which was recorded in this same room. It will be a pleasure to make you listen to some excerpts.

Our technique for recreating the acoustics of a room is based on many unpublished data and measurements that we have collected over several years and what we want to keep confidential (more than 300 concert halls around the world, including nearly 40 British great concert halls). The creation of IR is part of the recording services that we offer on our website.

We also have a great experience in classical music publishing and are currently looking for artists to create a new label ... let me know by e-mail if this might interest you.

Cheers

Mickael

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

Quite good, Gilles.

The ideal for Haydn sonatas, however, would be a larger room with a reverberation time between 1.6 and 1.8 seconds.

Many thanks, Gilles!

The Dixon Studio Theatre IR is quite nice, as is your fxp & demo, though the material differences between Dixon vs Holywell undoubtedly change the color of things considerably...

here's a quick&dirty little study i just recorded featuring use of the una ("Mozart Rail"), due ("soft" pedal), and tre corde registers of the Broadwood using my own Broadwood fxp and the Dixon IR: 

https://www.forum-pianoteq.com/uploads...._Dixon.mp3

Dussek - Sonata in C, Op. 31 n.3 (1795) - Air
1796 Broadwood, a¹=422.7 Young (1799)
Dixon Studio Theatre IR

https://images2.imgbox.com/68/2b/JKmsXUhd_o.jpg

(undoubtedly this would benefit from some eq... inspired by Mickael, i've gone ahead and downloaded the Lindell TE-100 plugin and, while i don't normally mess around with DAWs and plugins (preferring to use Pianoteq alone without intention to record), have decided to have some fun with it... we'll see what if anything comes of it )

to be honest, i struggled with finding something from the London School repertoire which i felt would really justify the use of due corde, nevermind una corda... my hunch is that such devices, as with so much of the experimentation with stops and gadgets in keyboard instruments over the years (down to the present with our new "Mozart Rail" i suppose) are really, without pejorative distinction, generally more for Liebhaber rather than Kenner (as CPE Bach might have it)...

i had toyed with the idea of rendering this also with Preston's temperament, but it's obviously such an unadventurous little ditty that it didn't really seem worthwhile... 'will have to wait for when i get around to actually setting down some Haydn...

really, what my project (such as it is) is about is continuing exploration of Pianoteq's capabilities (and my own in using it), as well as getting to have fun with all this lovely London School repertoire (Haydn of course, but I'm very interested as well in the whole musical scene around Therese Jansen). 

My reference recording (Program Ten - The London Scene, 1794-95) is from Tom Beghin's The Virtual Haydn (see links above for more about Tom's project), and goal is to see how close I can get our Broadwood to sounding like Bilson's Clementi in those recordings.  From there I'll work backwards toward integrating what's been gleaned from developing the recorded sound into my odd quad setup (as described here) with the aim of inching ever closer to the holy grail of "the instrument in the room".

i'm curious though about some of your observations...

This is typically the most appropriate acoustics for classical music period.

most music of this period (along with the instruments that were developed to support it) was written for and performed in salons and small chambers, while Holywell was quite the novelty at the time in its idea of having a "public" & dedicated space for music performance, so how would this be "the most appropriate acoustics for classical music"?  what makes for "appropriateness" in this regard anyway??

similarly, you say

The ideal for Haydn sonatas, however, would be a larger room with a reverberation time between 1.6 and 1.8 seconds.

to my ear, Holywell is already plenty wet (if not too much so), so what about Haydn makes you want more space?  and what then about Mozart or Beethoven??  reverb time between 1.8 & 2.0??? and so does each composer then have their own "sweetspot" of space/reverb in your opinion????

Here's a video from the Oxford Holeywell Music Room with some footsteps in the beginning: https://www.youtube.com/watch?v=IOrsz15uX5k which give a impression of what an IR should sound like. I guess Altiverb's Mozart Hall at Konzerthaus Vienna might come close.
But there will be many more, e.g. Spacedesigner Small Hall, and Guitar Hall (1,6s, 1,7s).
This free one might come close https://fokkie.home.xs4all.nl/IR.htm Church Schellingwoude

I do have a rather large IR-collection, but haven't really dived into modeling of IR's. Voxengo IMpulse Modeller is ok-ish, but you can only design the walls, not floors or ceiling. (And it's very old...) Another simple one is  QuickQuak Rayspace http://www.quikquak.com/prod_rayspace.html which works in real time. (only 32bit)
Probably this is a more professional solution: https://odeon.dk/

Yes, I know Tom Beghin's recordings and his project The Virtual Haydn ...

I also read the description of your setup and I understand what you are looking for. However, I don’t think that using reverb (even with subtlety) will allow you to achieve the realism of a ‘‘resonance case’’. Resonance should not be confused with reverberation. These are two very different things.

Your experiment remains interesting, but in your place (if I had the time) I would build myself a soundboard with high quality speakers to fix it to my controller, rather than use speakers by pointing them up. In theory, the problem when you do this is that the sound disperses too much in the air, whereas with a soundboard and a lid, the sound will be more concentrated. This should strengthen the bass, give more body and maybe even add the resonance of a ‘‘case’’.

It’s important to understand that the only original thing at that time was that the Holywell Music Room was one of the few public places dedicated to music, but it was not the only room with similar acoustic characteristics in which chamber music was regularly played.

It must also be considered that what you call small rooms and salons has absolutely nothing comparable to what we call small rooms and salons nowadays.

Of course, there were all types of rooms and salons at the time (from the smallest to the largest), but the private high places of classical music were mostly in castles, villas, etc.

The large Esterhazy Castle concert hall in Austria (translated nowadays as a medium-sized chamber concert hall) is the perfect example, Haydn having worked there for almost 30 years. This is four times larger than the Holywell Music Room with a similar reverberation time.

You may play or record Haydn in any venue if you wish, but chamber music concert halls are specifically designed by architects and acousticians to achieve an optimal reverberation time between 1.6 and 1.8 seconds, for the classical period.

The Holywell Music Room has long been regarded as the ideal room type for chamber music, and if you want to get closer to it, the Dixon Studio Theater can’t be considered as an appropriate choice (although Gilles’s recording sounds pretty good). Indeed, theater acoustics are not intended for chamber music, and their short reverberation time is essentially dedicated to the clarity of spoken word diction.

_DJ_ wrote:

Too wet, no. It depends on the microphones type and where you place them.
Otherwise, it would mean that you consider the vast majority of Haydn sonatas recordings too wet. I don’t think that's your case.

I did a very long inventory of almost all the available recordings of Bach, Handel, Scarlatti, Haydn and Mozart, from the 40s to the present. So I can tell you where these composers are most often recorded.

_DJ_ wrote:

Of course, no. The subject here is Haydn ... and the ideal reverberation time for Haydn is the same for all composers of the classical period.

In fact, the ideal room acoustics depends more on the genre and the period than the composer (although some concert halls have been designed with specific works in mind as a reference).

Also be aware that there are acoustic standards in each country, for each type of room, and that the choice of reverberation time is not hazardous.

I hope this will help you

Voxengo Impulse Modeller, QuikQuak and Odeon are good software, but you will never be able to reproduce Holywell without serious knowledge in room acoustics.

It's better to turn to existing IRs.

of course, "optimal" in this field is merely preference.  it may be aggregated preference and subjected to scientific method, but it remains preference none the less and, as such, is entirely subjective.  notions of an "ideal" acoustic (such as Beranek's prescription of T(sub60)=2.0 for symphonic music) may carry some intersubjective weight, but they remain just that: one person's claimed ideal and without actual objective basis.  and never mind the wide host of variables that play into listeners' perceptions beyond reverberation time...

all of which is to say that, 1.6-1.7 seconds reverb is not somehow the "mathematically perfect" amount for "classical" music.  it is merely the mean reverb time that has been found to be pleasing to the greatest number of people, but it doesn't follow then that it's somehow a magic bullet and necessarily "ideal for Haydn sonatas"...

and speaking of genre & period, as a musicologist/historian, when i think "classical" in terms of music i think c1749-1802... so i agree with you here that "ideal acoustics" are much more a function of what's being performed than anything inherent to a given space (a space which works well for Mozart's orchestra on period instruments, say, may well be entirely unsuited for that of Mahler with a full modern orchestra and vice versa).

it would mean that you consider the vast majority of Haydn sonatas recordings too wet. I don’t think that's your case.

to be honest, outside of work necessities and the odd gem that happens to fall into my hole, i largely gave up on listening to recorded music decades ago and have no idea about "the vast majority of Haydn sonatas recordings".  The last time i had to listen to recordings of Haydn was in those silly undergrad "drop-the-needle" exams, so Tom's recording is really the only Haydn recording i have in my ear and, yes, to my taste i find his recording in Holywell too wet for the intimate oratory of Haydn's music (though his playing is of course magnificent).  But i'm still keen to see how close with Pianoteq one can come to reproducing that sound quality using Holywell, taking Tom's recording as a sort of benchmark for things...

Hi _DJ_

It would be a pleasure to answer anything you say if it could really help you, but here are some answers:

_DJ_ wrote:

No.

The vast majority of the recordings nominated and awarded by the public and specialists are recorded in rooms that correspond to all the acoustic characteristics I am talking about (and of course, the reverberation time is not the only criterion, but it's the most important... edit: in the sense that it's the first thing you look at). It's the same for all the most appreciated venues around the world for Haydn’s music in recital. This is an objective fact, even if you didn’t know it and you don’t have real knowledge in this field.

You have to go further than Beranek if you want to understand room acoustics.

Otherwise, it’s no coincidence that Haydn's great performers and reputed sound engineers choose this type of concert hall as a priority when they can.

Again, you can play and record Haydn anywhere if you want. Fortunately, there is no mandatory rule in this field.

I just took the time to make consistent and enlightened suggestions to bring you as close as possible to the Holywell Music Room… what originally was your request, it seems to me.

The only way to develop a culture of Haydn’s music is to listen to a wider variety of recordings. If you've ‘‘ never ’’ listened to anything other than Tom Beghin, it's normal for you to think that this is the only type of recording you like, and that this seems the most appropriate one.

Voxengo Impulse Modeller and QuikQuak are toys, but Odeon is the type of software used to predict the acoustics of not yet build concert-halls. I think this way of making IR's, modeling instead of recording is very similar to Pianoteq vs sampled piano's.

No! It's not better to turn to existing, recorded IR's, it's more convenient (a lot more convenient). A really well modelled IR is better, better Signal to Noise ratio, cleaner, no coloration because of used equipment, much closer to perfection. Just like a perfectly modelled Grand is better than a sampled one.

Good point! Looking for IR's of rooms in castles and villas might give similar acoustics as the Holywell.

Logic Spacedesigner has a few rooms of Residenz Würzburg. http://www.residenz-wuerzburg.de/deutsc.../index.htm
I think they are called are called Prince Hall One, Prince Hall Two and Prince Hall Three;
Also a few from a Rathaus, I think it's Luneburg, it's called Archaic Courtroom.
And from Ingelheim Würzburg  http://erdteilallegorien.univie.ac.at/e...r-weisser# . They are called and Chamber One, Chamber Two, Chamber Three and Chamber Four. Which is a pity, because the Rooms in the Residenz are called: Kleiner Weisser Saal (Chamber One), Kleiner Gruener Salon (Chamber Two) and Gelber Salon (3) and Kleiner Gruener Salon (4).

My only intention was to help you find the room that is closest to the Holywell by sharing my knowledge in this field.

I don’t think I represent any authority, and I regret that you could interpret it that way.

I hope you understand it and wish you to find your "Holy Grail".

Sincerely

Mickael

PS: I just hadn't seen your email yet, but it means a lot to me to answer it.

No! It's not better to turn to existing, recorded IR's, it's more convenient (a lot more convenient). A really well modelled IR is better, better Signal to Noise ratio, cleaner, no coloration because of used equipment, much closer to perfection. Just like a perfectly modelled Grand is better than a sampled one.

I agree with you.

I guess Altiverb's Mozart Hall at Konzerthaus Vienna might come close.

The Mozart Hall is much larger than the Holywell Music Room, and it is not very suitable for Haydn when it is empty.

That said, András Schiff recorded Mozart in this concert hall ... so you can try.

The large Esterhazy Castle concert hall in Austria (translated nowadays as a medium-sized chamber concert hall) is the perfect example, Haydn having worked there for almost 30 years. This is four times larger than the Holywell Music Room with a similar reverberation time.

You may play or record Haydn in any venue if you wish, but chamber music concert halls are specifically designed by architects and acousticians to achieve an optimal reverberation time between 1.6 and 1.8 seconds, for the classical period.

? So why not the Mozart Hall then?

By saying this, I took into account that _DJ_ didn’t want the piano to be too wet, because the particular acoustics of the Mozart room is not easy to manage when there is no audience.
This is one of the reasons why there are relatively few piano recordings (classical period) in this room.

However, it’s an excellent chamber music hall for concerts with the public.

Again, this is not forbidden, but the acoustics of this concert hall is very different from the Holywell Music Room.

PS: There are many interesting rooms to try in your selection '' castles and villas '' ...

Thanks Mickaël,

I think we've "gotten our wires crossed" a bit here, but I do appreciate the insights you've shared (even if we're not entirely seeing eye to eye on things).

To be clear, while I have no real interest in recording per se, my concern with Holywell and Beghin's virtual use of it in his bleeding-edge recording is solely as a point of reference for working with Pianoteq.  My own acoustic predilections (informed by a long & deep devotion to live playing on historically-appropriate instruments vs the offerings to be found in recordings) are secondary in this regard and I'm rather more focused on the idea of replicating this particular sound for its utility in what it may reveal about the underlying instrument model, and how that might then inform an fxp of the Broadwood (and beyond) without added spatial reverberation.

In any event, I'm in receipt of your email and will look forward to hearing from you further at your convenience. 

cheers,
dj

Yes, in general this is a problem with IR's from concert halls etc, because they are designed to have good acoustics with public; IR's are made without public, so usually give over-acoustic results. Might be better to explore IR's of spaces that are designed to sound good without public, so recording studio's, scoring stages etc.
Or, when using modeling software, by placing virtual people inside the hall ;-)

Very thought-provoking discussion! I know little about the technical details of acoustics, but yes, there is a heck of a lot of difference between the sound properties of an empty hall and a populated one.

Yes, exactly!

The acoustics of a concert hall are mainly designed to be optimal when there is an audience, but some of them are very suitable for non-public recordings (La Chaux-de-Fonds, Henry Wood Hall, Hannover Beethovensaal, etc.).

Also, many albums of Haydn’s sonatas have been recorded in studios in recent years. Especially at Teldex Studio in Berlin (the Harmonia Mundi base camp)

Teldex Studio and La Chaux-de-Fonds concert hall are available with Altiverb ...

The best is to find an ideal hall.

Could'nt you place virtual people who don't cough nor eat popcorn ?

Very funny!!!

I recognize that this deserves some explanation from me:

When you record in a virtual concert hall, with a virtual audience, the ''problem'' is precisely that you don’t hear people coughing and ‘‘eating popcorn’’, because it’s like playing in an empty hall with an ''inappropriate'' short reverberation time in relation to the size of the hall.

It’s not easy to explain, but I’ve already done several tests with a "fake" public to say that.
I just want to say that it's a little weird to listen to, and a bit unrealistic, because even when a real audience is silent, there's always some kind of background noise that adds some ambience to the natural reverb of the hall.

Moreover, if anyone knows a software that can simulate the public noise (without popcorn), I am very interested!

Another thing is that, usually, during a live recording, microphones are placed and mixed to get as little noise as possible from the audience. So, less concert hall ‘‘sound’’, and more piano direct sound.

Of course, you don’t have this problem to deal with a silent virtual audience (like a statue), but it sounds a little weird (to my ears).

So, I think it's better to find a more suitable concert hall to stay realistic.

Modartt are surely working on Audienceteq right now...?
Choose from a variety of presets (Jazz, Rock, Pop, Classical etc.), vary the age and condition of the audience, levels of coughing, shuffling, chair creaking, whispering...

So crazy! but it would be a very great idea!

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

If you observe the first seconds of silence of a commercial recording (without audience) with a spectrum analyzer, you will see that there is a lot of activity, especially below 100 Hz (from -70 dB approximately).

This represents the noise of analog devices, the hall ventilation system, the very low noise from the street, the parquet floor that cracks, etc.

Silence doesn’t exist!!! ... it's realism.

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

here's another test recording i just made, now with an alternate micing setup (perhaps closer to the reference recording i'm using?) and with various tweaks to my fxp for the Broadwood... not there yet, but hopefully getting closer! 

https://www.forum-pianoteq.com/uploads....adagio.mp3

Cramer - Sonata in G, Op. 8 n.2 (1795) - Adagio con espressione
1796 Broadwood, a¹=422.7 Preston (1785)
Large Chamber IR

(as with the Dussek ditty i posted above, this was only a quick take to demo aspects of the instrument/rec setup and not meant to be any sort of an avowed musical statement)

oh, and this one is tre corde throughout and without editing or mastering.

for a mastered version of the same see here.

i was under the impression that most modern halls (and refurbished old halls) used material padding in the seats of proper type & sufficiency to mimic the "damping" effect of clothed human bodies...?

and, though i shudder to imagine it with the usual sort of concert-going audience, i wonder (completely idle & meaningless speculative fun here) how different the sound reflections would be from unclothed bodies...?  maybe this would make a "fun" project for some quirky grad student...  and surely a whole new twist to that old musicale the roar of the greasepaint—the smell of the crowd!

Mickael,
I owe you a huge apology which I'm happy to make here publicly!
Concerning reverb & "simulating case resonance", you are completely right and I'm dead wrong.  It turns out that the fxps I've been using were all built on 5.0 and I never properly updated them... and whatever "deficiency" I was trying to "correct" under the old model is no longer an issue at all under 6.0.  I don't know how much psychoacoustics is playing into this with the new model etc, but the sound is gorgeous and clean and indeed much closer to "reality".  Thanks so much for your insights here as much as for your grace...  I'm enjoying my very healthy dose of humble pie (as well as these beautiful "new" instruments)!
shamefaced, but wishing you cheers,
dj

Hi _DJ_

I am very pleased that my advice about the simulation of the ‘‘case resonance’’ was helpful!

I also believe that there are several ways to correct Pianoteq's minimal 'deficiency' to achieve perfection, but my reasoning is to always reproduce a realistic configuration.

Here are two recording tests we made yesterday with the Broadwood in a simulation of the Holywell Music Room and the Hanover Square Rooms. These are two great concert halls in which Haydn played during his stay in London.

These are first non-mastered tests, just to listen to the sound of the instrument in these two rooms ...

Cheers

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

thanks for that, Mickael, as well as for your email (the other points of which i'll respond to soon!).

these initial test recordings of yours have a very nice sound indeed, though your version of Holywell as presented sounds considerably drier to my ears than in Beghin's recording... i wonder though if that's more an effect of mic choice/placement than anything else...?  could you detail please a little of what your rec setup for this was as well as how you arrived at the "precise acoustics reconstruction" of your custom/private IR for Holywell?

also, while I appreciate that these recordings are "just to listen to the sound of the instrument in these two rooms", i personally find the "unmeasured sightreading" more distracting than helpful and I wonder if these are really the best recordings to be demo-ing your efforts with here...? 

cheers,

here for instance is a very quick little take i did for use as an audio test using the "Mozart Rail" & the Broadwood...

https://www.forum-pianoteq.com/viewtopic.php?id=5842

'nothing special or fancy, but i find its almost minimalist quality lets me for one, while tweaking fxps, focus on the sound artifact and not what's being played...
ymmv

Re: "Mozart Rail", Broadwood, Haydn, temperaments, Holywell, & acoustics

_DJ_, our Holywell IR simulation is '' exactly '' the same as Beghin's, with the only difference, that his engineers made measurements directly in the room, and we based ourselves only on data of private acoustic measurements of the same rooms.

What gives you the impression that my recording is drier is only due to the placement of microphones, equalization and normalization. You can easily record in a church with a reverb time of 5 seconds and give the impression that you have recorded it in your living room, just with the microphones placement.
My goal so far has not been to get closer to the Beghin version, but I can do it.
