Just in time with the music.

Note duration, also known as note value or tone value, is used in musical notation to express the relative duration between notes. A perfect note is equal to two half notes; it is equal to four quarter notes, eight eighth notes; sixteen sixteenth notes, and thirty-two thirty-second notes. It's just a ratio of note durations.

In musical works, only by adding the time signature can we know which note is a beat. Now take the ÷ beat as an example (that is, a quarter note is one beat, and each measure 4 has a duration of two quarter notes). Example 1 Music theory textbooks tell us: "V" is a beat. It makes us understand that do is the first half of the first beat, re is the second half; mi is the first half of the second beat, and fa is the second half.

The definition of time value:

1. On-duty date.

2. Current price, the price within a certain period of time.

3. It refers to the length of a note or rest, and also refers to the actual time occupied by a sound after it is emitted.

4. It’s the right time.
