On the modern grand you do no have to lift the key fully up to press it again. Therefore, you can play better legato without the pedal, and you can hit the same key faster.
The dynamic force distribution on the key travel is also different. Key travel has a completely different feeling.
- chrismorgan 5y agoThis is correct. If you’re interested in learning more, the key term to research is action. https://en.wikipedia.org/wiki/Action_(piano) https://en.wikipedia.org/wiki/Action_(piano) is a decent overview with a couple of diagrams, though fairly dry. Simplifying drastically, grands strike upwards and gravity returns the action to its base position, whereas uprights strike sideways, have shorter pivot points, and in the end have less weight making the action return, plus they often depend on fabric straps to help it to return in a timely fashion, which still results in significantly inferior key repeat rates. (A grand piano wouldn’t work at all upside down. An upright… hmm, I haven’t tried it but I suspect that you could actually get a little bit of sound out of some normally-inferior actions.)
- Doxin 5y agoI've been to a concert that had an upright piano rolling around the stage, being upside down at several points. Apparently getting it to work involved installing some extra springs in the piano. Unrelatedly they also had a trick piano where the whole backside and frame with strings would detach at the climax of the song and come crashing down to the floor on cue. Apparently they didn't need to tune the piano used for that an abnormal amount.
