+Percussion instruments are generally notated in a @code{DrumStaff}
+context and when notated in this way they are outputted correctly
+to MIDI channel@tie{}10, but some pitched percussion instruments,
+like the xylophone, marimba, vibraphone, timpani, etc., are
+treated like @qq{normal} instruments and music for these instruments
+should be entered in a normal @code{Staff} context, not a
+@code{DrumStaff} context, to obtain the correct MIDI output.
+
+Some non-pitched percussion sounds included in the general MIDI
+standard, like melodic tom, taiko drum, synth drum, etc., cannot
+be reached via MIDI channel@tie{}10, so the notation for such
+instruments should also be entered in a normal @code{Staff}
+context, using suitable normal pitches.
+
+Many percussion instruments are not included in the general MIDI
+standard, e.g. castanets.  The easiest, although unsatisfactory,
+method of producing some MIDI output when writing for such
+instruments is to substitute the nearest sound from the standard
+set.

+Because the general MIDI standard does not contain rim shots, the
