In simplified musical notation, adding a horizontal line under a note means that the sound has been reduced by half the time value, that is, the note is half a beat; adding two horizontal lines means that the sound has been reduced by half the time value and then reduced by half the time value. , that is, the note is a quarter beat.

The horizontal line under the note is called the minus time line, which means that the time value of the note is reduced by half. The more subtractive time lines there are, the shorter the note is. Each additional subtractive time line means it is shortened to half the length of the original note.

Duration is the length of each note when playing or singing. It is calculated using "beats". When you ask what the duration of a note is, you are asking how many beats the note is played. Use a horizontal line "-" to mark the note to the right or below to define the length of the note.

Introduction

Beat: It is the periodic and regular repetition of heavy beats and weak beats in music. In Chinese opera, the beat is called "ban, eye", "ban" is equivalent to the strong beat, and "eye" is equivalent to the sub-strong beat (middle eye) or weak beat.
