Rhythm
Bar (Measure)
A group of beats organised by the time signature.
In plain English
Written music is divided into small sections called bars or measures. In 4/4 time, each bar normally contains four quarter-note beats.
Try or listen for this
Count “1, 2, 3, 4” and then begin again at 1. You have counted one bar of 4/4.
Why it matters
Bars give musicians a shared way to locate, count, repeat, and discuss parts of a piece.
