Example 22 shows two typical ways to represent a triple pulse:
Under A, a dot has been added to the quarter note that now divides into the three eighths of the triple pulse. Under B, the normal duple division of the quarter note must be overridden by a slur and the number three to show the triple pulse. If the latter notation is used throughout a piece, it may be that only the first few triplets are notated as in B. The term simile may then be used to substitute for the triplet notation. At times the beam alone suffices to indicate an eighth note triplet if it is heard with a series of quarter notes consistently. See Burkhart, 5th ed., p. 207 (Mozart), p. 301 (Schubert), p. 327 (Chopin), p. 385 (Brahms), p. 390 (Fauré), and p. 529 (Crumb) for a variety of examples.
