A Tempo

A tempo, written as ‘a tempo’ in scores, instructs the performer to return to the original tempo of the piece. It is the standard cue used to close out any passage of tempo modification — ritardando, accelerando, rubato, allargando, or similar.

The marking is essential for ensemble coordination. Without an explicit ‘a tempo’, players have no way to know when the modified passage ends and the original pulse should resume. In conducted music the conductor’s gesture re-establishes the tempo; in chamber music and solo work, the performer must internalize the original pulse and recover it at the marked point.

A tempo is sometimes paired with other markings: a tempo, ma più tranquillo (‘at tempo, but more tranquil’) restores speed but adjusts character. Tempo primo is a stronger version meaning ‘the original tempo’ — used after extended passages where the original pulse has been thoroughly disturbed.

Italian, literally ‘at tempo’ — a (‘at’) + tempo (‘time, pace’).

Hear the original pulse before you play the first note after ‘a tempo’. Do not glide into it — recover it cleanly. In ensembles, the leader (conductor or first player) sets the pulse with a clear gesture or breath.
