Beat is a pattern of repeating stress at certain intervals according to the requirements of time signature. In other words, it is a fixed repetitive sequence of strong and weak sounds. Every beat is composed of units with fixed time value, and this beat unit is called beat. The duration of a beat can be quarter note, half note or eighth note. Beats are usually marked by fractions, the numerator represents the unit beat per minute of each bar, and the denominator represents the duration of notes in the unit beat.

Bar lines divide notes into regular units with alternating strengths and weaknesses.

It is alternating between strength and weakness, while 3/4 waltzes are alternating between strength and weakness. If there are more than three beats, there will be two different strong beats, such as 4/4, which is strong-weak and the second strong-weak; 6/8 is strong-weak-weak; The second strongest-weak-weak.
