Final answer:
In music, each note's duration is half of the duration of the next longest note value, creating a hierarchy of rhythmic possibilities.
Step-by-step explanation:
Each note in music has a duration that is half of the next longest note value. For example, if we consider a whole note as the longest duration in common time, a half note is half the duration of the whole note, a quarter note is half the duration of the half note, and so on. This pattern continues down through eighth notes, sixteenth notes, thirty-second notes, and beyond. This system allows for a wide range of rhythmic diversity in music composition and performance.
