> Is it (the transposing of instruments) like this everywhere or is it different in some parts of the world? Japanese flutes are transposing. The scales and keys are all numeric, instead of the alphabetic system that western music uses. For example, my #6 flute (western: "B flat") sounds 2 half-steps lower than a #8 flute ("C"). A piece might be written to start on note #4 (and not say what absolute pitch #4 means), so it would sound different depending on what flute you're playing. > The musicians mostly can adapt on-the-fly. Is there something similar in classical music ? When I played the cello when I was young, I remember having some sheet music put in front of me once, and being asked to play it in a different key ("up a third" or something) as part of an ensemble. It wasn't especially fast or complex music, but that was a skill that was apparently expected of a high school amateur. It's not as hard as it sounds, but it's also something we never really practiced. Reasons I can think of would be when working with a soloist who has a particular vocal range, or if you find a piece that's not written for your instrument in particular (e.g., piano score to string quartet). I don't think anyone transposes a piece like Beethoven's 9th. When you want an entire symphony to transpose (usually up to "sound brighter", or down to emulate baroque period instruments), you just tune to a different "A".
