The number of beats depends on the time signature. For example, in 4/4, the quarter note is one beat, the eighth note is half a beat, and the half note is two beats. But if it is 3/8, then the eighth note is one beat, and the quarter note is two beats.

You just need to remember the relative relationship between the time values ??of these notes. The specific number of beats still depends on the time signature.

Whole notes refer to hollow white notes without stems and tails.

Half note A note composed of a stem and a hollow note head is called a "half note", and its duration is 1/2 of a whole note.

A quarter note refers to a note duration. In staff notation, a quarter note is a solid elliptical note plus a stem without a tail, and the length of a quarter note is one-quarter of a whole note.

Eighth note? is a note duration. If you divide the whole note into eight equal parts, you can get the eighth note. The more you divide it, the shorter the duration. The duration of the eighth note is 1/8 of the whole note. Since the whole note is four beats, the eighth note is half a beat. . In staff notation, an eighth note is represented by a solid oval note head plus a stem with a flag-like tail.

Sixteenth notes are notes with black faces and two tails. It is half smaller than an eighth note (it is equal to 1/16 of the duration of a whole note). One beat can be divided into four equal parts, each part is a sixteenth note, and is twice as fast as an eighth note. , in a whole beat, two sixteenth notes are on the falling beat, and the other two are on the starting beat. Sixteenth notes are timed like this: 1, e, amp;, a.
