(TMS) Measures Lesson

Measures

Vertical black bars called bar lines divide the staff into measures. This staff has been split into two measures. Dividing music into measures provides regular reference points to pinpoint locations within a piece of music. It also makes written music easier to follow, since each bar of staff symbols can be read and played as a batch. The word bar is more common in British English, and the word measure is more common in American English, although musicians generally understand both usages. In American English, although the words bar and measure are often used interchangeably, the correct use of the word 'bar' refers only to the vertical line itself, while the word 'measure' refers to the beats contained between bars.
