Upbeat (Ger. Auftakt).1. An unaccented
beat or beats that occur before the first beat of a following
measure. Also called
anacrusis or
pickup. In other words, this is an impulse in a measured
rhythm that immediately precedes, and hence anticipates, the
downbeat, which is the strongest of such impulses. It can be the last beat in a bar where that bar precedes a new bar of music.
