+Accordions are often built with more than one set of reeds that may be
+in unison with, an octave above, or an octave below the written pitch.
+Each accordion maker has different names for the @notation{shifts} that
+select the various reed combinations, such as @notation{oboe},
+@notation{musette}, or @notation{bandonium}, so a system of symbols has
+come into use to simplify the performance instructions.
