allegro

allegro - adj - brisk or rapid in tempo

So far, the words posted have mentioned tone (in terms of it's range and volume), but this word (and a few more I'll submit unless Natalie beats me to it :) have to do with tempo, or how fast or slow a piece is played. One of the things about music seems to be it's ability to convey meaning by relativity. Specifically what is piano or forte? How quiet should piano be? Well, obviously, it should be quieter than loud! So, specifically, how fast (or brisk) should allegro be? Listen to several renditions of Bach's fugues and you'll hear several interpretations of allegro
