Time signature is a symbol used in music score, which is marked in the form of fractions. Each score is preceded by a time symbol. If the middle rhythm changes, the changed time symbol will be marked, which is like a score, such as 2/4, 3/4, etc.
The denominator means that a beat is represented by a quarter note, for example, 2/4 means that a beat is represented by a quarter note, and each bar has two beats.
Molecules represent how many beats there are in each bar. As mentioned earlier, 2/4 beats means taking a quarter note as a beat, 2 beats in a bar, 3/4 beats in a quarter note, and 3 beats in each bar ... The reading method is to read the denominator first and then the numerator. For example, 2/4 is called 42 beats, 3/4 is called 43 beats and 6/8 is called 86 beats.
The time signature should be marked at the beginning of the music, after the first line of the music.
When marking the time signature on the score sheet, three lines (the line in the middle of the staff) should be used as the horizontal line of the score, and there is no need to draw another horizontal line. If you don't change the beat in the middle of the music, write it at the beginning. If you change the beat in the middle, you need to mark the new beat number.
One beat, two beats.
Two or four beats take a quarter note as one beat, and each bar has two beats. This is called 2/4 beat, and there are two beats in a bar. The first beat is a strong beat and the second beat is a weak beat. In a bar, there is only one strong beat and one weak beat, and then each bar repeats itself. This 2/4 rhythm is very suitable for parades, so most marches adopt this 2/4 beat form.
Two three-quarters beats.
Take a quarter note as a beat, and there are three beats in a bar, which is called 3/4 beat. In other words, there is a strong beat and two weak beats in a bar, and each bar is repeated. The first beat is a strong beat, and the second and third beats are weak beats, that is, 3/4 beats. This rhythm is suitable for rotation, so it is often used for waltzes.
Three, four, four.
It takes a quarter note as a beat, and each bar has 4 beats, which is called 4/4 beats. In the 4/4 beat, the first beat is a strong beat, and the second beat is.
Weak beat, the third beat is the second strong beat, and the fourth beat is the weak beat.
Four beats, six beats/eight beats.
Different from 2/4 and 3/4 beats, it takes an eighth note as a beat, and each bar has 6 beats, so in each bar, the first beat is a strong beat, the second beat and the third beat are weak beats, the fourth beat is a strong beat, and the fifth beat and the sixth beat are two weak beats, so each bar has 6 beats, and these beats appear repeatedly.
