The equivalence between the different note values is arranged proportionally. A constant duple relationship applies to all note values, where each note value corresponds to half the value of the next larger and twice the value of the next smaller (figure 2).
Observing this principle, the quarter note, for example, has twice the value of one eighth note (the next smaller) and half the value of one half note (next larger); the eighth note, has twice the value of one 16th note (the next smaller) and half of one quarter note (next larger); and so on.
Figure 2 shows the equivalence between all note values in relation to the whole note, the largest note value: one whole note equals to two half notes, four quarter-notes, eight eighth notes, sixteen 16th notes, thirty-two 32th notes, and sixty-four 64th notes.
