Will someone please tell me what this is used for...maybe i'm not in the right forum but you all know pianos so someone ought to be able to help. I know what the damper and una corda are used for but i have no idea about sostenuto pedal. Give me some examples where you've HAD to play it, and then if anyone can, tell me exactly what the point of them are. PLEASE
3. Of course, some upright pianos make the middle peddle engage a piece of felt to soften the piano's sound... but this has nothing to do with "Sostenuto."
That's exactly how I'm using it xvimbi. I play a very loud chord, both hands, depressing the middle and right pedals. Right hand goes on to play quite a long cadenza, while the that bass note is being held the whole time. Then both pedals are raised and lowered at the same time at the beginning of each measure for several lines, sustaining the first bass note of each measure while the treble notes are played with RH.
