play (“8CDEFGAB>C”) – plays one octave of 8th
notes from middle C
play(“<BAGFEDC”) – plays scale in reverse in 8th
notes if it follows previous line
play (“>4CDEFGAB”) – plays one octave of
quarter notes one octave up from middle C
play (">6CpC+pC-") – plays one octave up from
middle C, a C 16th note, a rest, C sharp, a rest,
and a C flat
play(“1C2C4C6C”) – plays whole, half, quarter,
and 16th C note
