In music, the note value that is worth the entire number of beats in one measure depends on the time signature of that measure. For instance:
- In 4/4 time, a whole note is worth 4 beats, which corresponds to the number of beats in a measure.
- In 3/4 time, a dotted half note is worth 3 beats.
- In 2/4 time, a half note is worth 2 beats.
Therefore, the specific note value that holds this significance is a whole note in 4/4 time, a dotted half note in 3/4 time, and so on, based on the time signature in use.
