Final answer:
A whole note has the same rhythmic value as 4 beats in music notation.
Step-by-step explanation:
The rhythmic value of 1 whole note is equivalent to 4 beats or counts in music notation. This means that a whole note receives the same length of sound as 4 quarter notes, 2 half notes, or 8 eighth notes. For example, if a quarter note is counted as '1', then a whole note would be counted as '1 2 3 4'.
