Rhythm characteristics refer to the rules that express fixed unit duration and intensity in music. For example, the characteristics of the two-beat beat are the cycle of strong and weak beats in each measure; the characteristics of the three-beat rhythm are the cycle of strong beat, weak beat and weak beat; the characteristics of the four-beat rhythm are the cycle of strong, weak, sub-strong and weak beats, etc. .

The time signature of music beats can usually be divided into:

1/4 beat: 1/4 beat is a quarter note, with 1 beat per measure.

2/4 beat: 2/4 beat is a quarter note, with 2 beats per measure, and there can be two quarter notes. Strong, weak.

3/4 beat: 3/4 beat is a quarter note, with 3 beats per measure, and there can be three quarter notes. Strong, weak, weak.

4/4 time: 4/4 time is a quarter note as one beat, each measure has 4 beats, and there can be 4 quarter notes. Strong, weak, sub-strong, weak.

3/8 beat: 3/8 beat is an eighth note. Each measure can be one big beat, but there are actually 3 beats. There can be 3 eighth notes. Strong, weak, weak.

6/8 beat: 6/8 beat is an eighth note, and each measure can be divided into two major beats. However, in fact, each measure has 6 beats, and there can be 6 eighth notes. Strong, weak, weak; second strong, weak, weak.

There are also rare 8/8 and 8/16 beats. The former uses 8th notes as one beat, and the latter uses 16th notes as one beat.

The denominator of the time signature represents the basic duration of the beat, that is, how many quarter notes are used as one beat, and the numerator represents how many beats there are in each measure. 2/4 means that one beat is a quarter note, and there are two beats in each measure; 3/4 means that one beat is a quarter note, and there are three beats in each measure; 3/8 means that one beat is an eighth note, and there are three beats in each measure. shoot.

There are only three denominator parts of the time signature: 2, 4, and 8. That is to say, half notes, quarter notes, and eighth notes are used as the basic time values ??of the beats.

Extended information

The cycle of music beats is always carried out by alternating strong beats and weak beats. This alternation cannot be chaotic or arranged arbitrarily, but forms the smallest rhythm according to certain rules. The beat organizes a section, and then the cycle continues based on it.

When there is only one weak beat between two strong beats, "two beats" refers to the time signature of 2/4; when there are two weak beats between two strong beats, The "triple beat" of time refers to the time signatures of 3/4 and 3/8; the "four beat" of three weak beats between two strong beats usually refers to 4/4.

Two sections are separated by a "section line". The bar line is a thin line perpendicular to the staff, with five lines on top and one line on the bottom, which just cuts off the staff. No matter how far away the upper and lower lines are from the staff, the bar line cannot go beyond the staff.

Draw two bar lines in the last section of the work, and the one on the right is thicker, indicating the end of a work or a paragraph. The beat after the bar line must be a strong beat, and there is only one strong beat in each bar, and the rest are weak beats.
