Expanded version of Invention #1 composed by Eran Talmor

Hello All,

Some explanation is required, regarding this upload.  This four-fold expanded composition was created in midi -- not a live performance -- by printing a downloaded copy the original score, and then step entering the notes into MakeMusic's 'Finale' notation software.  Next, I exported the Finale version to a standard midi file, and imported the same in Digital Performer.

Once in Digital Performer, I copied and pasted three additional copies of the file in succession.  Leaving the original version essentially alone, the second version involved transposing the left hand part up an octave (and in some places, two octaves) and transposed the right hand part down an octave (and in some places, two octaves).

The third and fourth versions were similar to the two first versions, with the exception that the left hand part was basically melodically inverted in the third version, and the right hand part was inverted melodically in the fourth version.

For those unfamiliar with the term 'inversion', this means that I essentially turned the individual intervals of notes upside down.  Restated, if a particular interval went up a perfect fifth in the original version, I changed it to go down a perfect fifth.  There was some creative editing going on with these inversions, as I strove to keep the inverted intervals within the Aeolean scale of C Minor and its dominant G Minor tonality as needed.

Lastly, using a variation of quantization in Digital Performer, I proceeded to make the rhythm "swing" a bit, by making the even eighth note / quaver rhythm into a slightly elongated eighth note / quaver and a slightly contracted sixteenth note / semiquaver.

Hopefully this explains how Mr. Talmor's composition was transmogrified, and that the composer will not be angered by this undertaking.  This elaboration was done in appreciation of the composer's fine contrapuntal composition.  As this was done in the midi format, it is rather apparent upon listening, that the file was not performed live.

Cheers,

Joe

Hello Eran,

Thank you for your prompt reply.  Of course you are correct in my missing a natural sign in your piece.  Regarding inversion, it was a rather free exercise in performing an inversion of one entire line -- as such, certain intervals had to be compromised in order to make the counterpoint remain in the context of the key signature.  As you are most likely aware, there are multiple types of inversion -- strict interval inversion, and that which preserves the tonality.  These are two aspects that Bach used in many of his works.

For example, in his Kunst der Fuge, there are several examples where he used accidentals to prevent a key change, and then there are also examples wherein he used accidentals to force a tonality change.

Beautiful composition on your part, by the way, and I thank you again for not having taken undue offense to my exercise without having consulting with you beforehand.

Cheers,

Joe
