Rubato

What it means

Literally stolen: you take time from one note and give it back to another. Over a longer stretch the tempo should average out.

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.
