Four sixteenth notes add up to ____ beat.

one

In music, a beat is a basic unit of time. The duration of a beat is determined by the time signature of a piece of music. The most common time signature is 4/4, also known as common time.

In 4/4 time, there are four beats in each measure, with a quarter note receiving one beat. Since a sixteenth note is half the duration of a quarter note, it takes four sixteenth notes to equal one beat.

Therefore, four sixteenth notes add up to one beat.
