I attended a concert once where a trombone soloist played his instrument pointing towards the strings of a grand piano (lid propped fully open, pianist depressing the pedal). The effect was amazing; the trombone made not only its fundamental frequency ring but also many overtones. The result was a powerful "echo" effect, shimmering and brilliant.
I'm wondering if anyone has tried a similar setup with cello. Would a cello solo playing a loud melody on its A string be a strong enough sound to cause a grand piano (lid open, sustain pedal depressed) to ring sympathetically? Does anyone know of a piece in the literature that does this?
