A half note has a duration of 2 beats in 4/4 time. An eighth note rest has a duration of 1/2 a beat.
To find out how many eighth note rests would equal the duration of a half note, you can calculate as follows:
- The half note lasts for 2 beats.
- Since each beat equals 2 eighth notes (because there are 2 eighth notes in one quarter note and 4 eighth notes in 2 beats), a half note is equivalent to 4 eighth notes.
Therefore, to represent the same duration as a half note, you would need 4 eighth note rests.
