The note values just discussed are adequate for the purposes of expressing virtually any possible rhythm. On occasion, you’ll find the use of various in-between beats. Examples include triplets, shuffle rhythms, and cross-rhythms. Another common type of in-between beat is the dotted note, which extends the value of a note category by another half. Therefore, a dotted half note (see Figure 4.10) is equivalent to a three-quarter note.
And a dotted quarter note (see Figure 4.11) is equivalent to a three-eighths note.
