And if you are a pianoteq forum member you are certainly in a risk group.

Ok, seriously speaking, I believe it would be nicer to model a old style (home made) glass harp, using glass cups, than model the Benjamin Franklin instrument.

The "home made" glass harp is fine tuned with water, controlling the amount of water inside, and not just the size of the glass cup circunference (limited variances available to buy).
A modelled version would allow to adjust the pitch of each note by changing the amount of water or changing the circunference size, or changing both.

And in the mathematical world of modelling, you could put each glass cup by side, or one over another without direct touch glass with glass, or even put similar to Benjamin Flanklin, in 90 degree lying, without drop the water.
Who cares about gravitation law???

Do you know this one ?

That's fascinating. Thanks for posting. It seems that there are three variations, then--the original glass, Franklin's spinning bowls, and ths later version with steel tubes.

That is so interesting! Thank you for posting this, Gaston.

I'm not sure how hard this would be. I would expect that glasses would have lower inharmonicity than a piano string--isn't the appeal of a glass harp partly the purity of tone? (But also the reason that we may not want to listen to a glass harp for more than a few minutes.) There would be no soundboard.The glasses are the transducers, yes? Velocity of strikes would still control amplitude, but would it also affect pitch slightly? Does the player subtly alter the pitch with slight variations in speed to prevent the drone of sine waves? And attack velocity would of course control the attack, or would be the gliding attack.

Pitch would also be controlled by the amount of water in each glass and\or the size and material or thickness of the glass? The interface would allow us to see the glasses and the water in them as we adjusted each? Or to choose different glasses that might accent different partials?

Or there's the spinning version that makes glass wheels turn, per this article:

But it drove people mad, and we might not want that.

Just a pipe dream, I suppose, or a glassy daydream.
