What is the definition of tempo

In musical terminology, tempo (Italian: "time") is the speed of a given piece of music.

Explanation:

The tempo is an Italian word used at the beginning of a piece of music that shows how slow or fast music needs to be played to convey a feeling or set the mood. Think of tempo as the speed of the music.

Tempo comes from the Latin word Tempus which means “time”. Once set, the tempo is effective throughout the music unless the composer states otherwise.
