Short for acceleration; in music, a direction to gradually increase tempo; in general use, a shorthand term for speeding up.
Modern abbreviation of 'acceleration,' from Latin 'accelerare' (ad- 'to' + celerare 'to hasten'). Shortened form common in musical scores and informal English.
Musicians live by 'accel.'—it's the instruction that builds tension and excitement in a piece. You'll see it written as 'accel.' in sheet music right before a climactic moment or transition.
