Wilfried Hou Je Bek recently asked us to transcribe this
ape call. We used our own
Do-Re-Midi system of text-based musical notation. The ape's call is rendered in 8/4 time (eight beats per measure) and lasts six measures. The ape's tones range from a low B to a high G (one octave plus six notes). For an explanation of the melody line and tone durations, see the
Do-Re-Midi specifications.
