getting faster

What it means

accel. above the staff: the tempo gradually picks up. Unlike a new tempo marking it describes the way, not the destination.

Photograph a page of sheet music or play the melody — Anotona finds the key, engraves the notes and transposes them into any other. Free.

Every note on this page is computed, not typed in — following the rule that also makes F# major spell its seventh degree E#, not F.
