Question:

Why do you rehearse for perfromances?

Best Answer - Chosen by Asker: As a former performing musician and currently a performing actor, I can tell you that usually, the more you practise (rehearse) a piece, a play, a movie scene, a dance, etc. the better the final performance will be. As you rehearse, your mind and body become more comfortable with going through the notes, lines, steps, etc. and remember them more easily. The exception would be performing things that aren't scripted or written down--improvisations. In these cases you can't rehearse. You can only work to be sure your mind and body know how to be loose and free to make up the music, lines, or dance steps on the spot.
