1. Commonly used rhythm patterns within one beat: quarter note, twenty-eight, eighty-six, sixteen-eight, four sixteens, small (front) dot, back dot, dot 16. Minor syncopation and triplet.

2. Rhythm patterns within two beats (major syncopated rhythm and changes and large dotted rhythm and changes): major syncopation (eight cuts to eight), eight cuts to sixteen, sixteen cuts to sixteen, Sixteen cut to eight, big point attached, sixteen attached, back attached (two beats).

In music, those rhythms that have typical characteristics and appear repeatedly are called rhythm patterns, which are divided into two categories: basic rhythm patterns and compound rhythm patterns.

1. The basic rhythm pattern actually refers to the composition of one (or two) unit beats. The focus is on the smoothness of the beat and the accuracy of the pitch value when sight-singing.

2. Compound rhythm patterns are composed of several basic rhythm patterns. In the progress of music, several basic rhythm patterns can form a new rhythm. If this new rhythm is used repeatedly in the music, a compound rhythm pattern with obvious characteristics will be formed. The clever use of compound rhythmic patterns is an important technique for musical development in composition (repeated repetition of rhythmic patterns), and is also an important focus in music analysis.
