@node Basic percussion notation
@unnumberedsubsubsec Basic percussion notation

@cindex percussion
@cindex drums

Percussion notes may be entered in @code{\drummode} mode, which is
similar to the standard mode for entering notes.  The simplest way
to enter percussion notes is to use the @code{\drums} command,
which creates the correct context and entry mode for percussion:

@lilypond[quote,verbatim]
\drums {
  hihat4 hh bassdrum bd
}
@end lilypond

This is shorthand for:

@lilypond[quote,verbatim]
\new DrumStaff {
  \drummode {
    hihat4 hh bassdrum bd
  }
}
@end lilypond

Each piece of percussion has a full name and an abbreviated name,
and both can be used in input files.  The full list of percussion
note names may be found in @ref{Percussion notes}.

@cindex clef, percussion
@cindex percussion clef

Note that the normal notation of pitches (such as @code{cis4}) in a
@code{DrumStaff} context will cause an error message.  Percussion clefs
are added automatically to a @code{DrumStaff} context but they can also
be set explicitly.  Other clefs may be used as well.

@lilypond[quote,ragged-right,verbatim]
\drums {
  \clef percussion
  bd4 4 4 4
  \clef treble
  hh4 4 4 4
}
@end lilypond


There are a few issues concerning MIDI support for percussion
instruments; for details please see @ref{Percussion in MIDI}.

@node Drum rolls
@unnumberedsubsubsec Drum rolls

Drum rolls are indicated with three slashes across the stem.  For
quarter notes or longer the three slashes are shown explicitly,
eighth notes are shown with two slashes (the beam being the
third), and drum rolls shorter than eighths have one stem slash to
supplement the beams.  This is achieved with the tremolo notation,
as described in @ref{Tremolo repeats}.

@lilypond[quote,verbatim]
\drums {
  \time 2/4
  sn16 8 16 8 8:32 ~
  8 8 4:32 ~
  4 8 16 16
  4 r4
}
@end lilypond

Sticking can be indicated by placing a markup for @code{"R"}
or @code{"L"} above or below notes, as discussed in
@ref{Direction and placement}.  The @code{staff-padding} property
may be overridden to achieve a pleasing baseline.

@lilypond[quote,verbatim]
\drums {
  \repeat unfold 2 {
    sn16^"L" 16^"R" 16^"L" 16^"L" 16^"R" 16^"L" 16^"R" 16^"R"

@node Percussion staves
@unnumberedsubsubsec Percussion staves

@cindex percussion
@cindex drums

A percussion part for more than one instrument typically uses a
multiline staff where each position in the staff refers to one
piece of percussion.  To typeset the music, the notes must be
interpreted in @code{DrumStaff} and @code{DrumVoice} context.

@lilypond[quote,verbatim]
up = \drummode {
  crashcymbal4 hihat8 halfopenhihat hh hh hh openhihat
}
down = \drummode {
  bassdrum4 snare8 bd r bd sn4
}
\new DrumStaff <<
  \new DrumVoice { \voiceOne \up }
  \new DrumVoice { \voiceTwo \down }
>>
@end lilypond

The above example shows verbose polyphonic notation.  The short
polyphonic notation, described in @rlearning{I'm hearing Voices},
can also be used.
For example,

@lilypond[quote,verbatim]
\new DrumStaff <<
  \drummode {
    bd4 sn4 bd4 sn4
    << {
      \repeat unfold 16 hh16
    } \\ {
      bd4 sn4 bd4 sn4
    } >>
  }
>>
@end lilypond

There are also other layout possibilities.  To use these, set the
property @code{drumStyleTable} in context @code{DrumVoice}.  The
following variables have been predefined:

@c TODO: decide what to do about this table.  (ie verbatim or not)
@table @code

@item drums-style
This is the default.  It typesets a typical drum kit on a
five-line staff:

@lilypond[quote,line-width=10.0\cm]
nam = \lyricmode {
  cymc cyms cymr hh hhc hho hhho hhp
  cb hc bd sn ss tomh tommh tomml toml tomfh tomfl }
mus = \drummode {
  cymc cyms cymr hh hhc hho hhho hhp \break
  cb hc bd sn ss tomh tommh tomml toml tomfh tomfl s16 }
\score {
  << \new DrumStaff \with {
       \remove "Bar_engraver"
       \remove "Time_signature_engraver"
       \hide Stem
       \override Stem.Y-extent = ##f
     } \mus
     \new Lyrics \nam
  >>
  \layout {
    \context {
      \Score
      \override LyricText.font-family = #'typewriter
      \override BarNumber.transparent =##T
    }
  }
}
@end lilypond

The drum scheme supports six different toms.  When there are fewer
toms, simply select the toms that produce the desired result.  For
example, to get toms on the three middle lines you use
@code{tommh}, @code{tomml}, and @code{tomfh}.

@item agostini-drums-style
Invented by the French percussionist Dante Agostini in 1965, this notation is
commonly employed in France but also elsewhere.

@lilypond[quote,line-width=10.0\cm]

  cb hc bd sn ss tomh tommh tomml toml tomfh tomfl }

  cb hc bd sn ss tomh tommh tomml toml tomfh tomfl s16 }
\score {
  << \new DrumStaff \with {
       \remove "Bar_engraver"

Here are some examples:

Two Woodblocks, entered with wbh (high woodblock) and wbl (low woodblock)

@lilypond[quote,verbatim]
% These lines define the position of the woodblocks in the stave;
% if you like, you can change it or you can use special note heads
% for the woodblocks.
#(define mydrums '((hiwoodblock default #t  3)
                   (lowoodblock default #t -2)))

woodstaff = {
  % This defines a staff with only two lines.
  % It also defines the positions of the two lines.
  \override Staff.StaffSymbol.line-positions = #'(-2 3)

  % This is necessary; if not entered, the barline would be too short!
  \override Staff.BarLine.bar-extent = #'(-1.5 . 1.5)
}

\new DrumStaff {
  \set DrumStaff.drumStyleTable = #(alist->hash-table mydrums)

  % with this you load your new drum style table

    wbl8 16 16 8-> 8 |
    wbl8 16 16-> ~ 16 16 r8 |
  }
}
@end lilypond

Note that in this special case the length of the barline must
altered with @code{\override Staff.BarLine.bar-extent #'(from . to)}.
Otherwise it would be too short.  And you have also to define the
positions of the two stafflines.  For more information about these
delicate things have a look at @ref{Staff symbol}.

A tambourine, entered with @q{tamb}:

@lilypond[quote,verbatim]

  \override Staff.StaffSymbol.line-positions = #'( 0 )
  \override Staff.BarLine.bar-extent = #'(-1.5 . 1.5)
  \set DrumStaff.instrumentName = #"Tambourine"
}

\new DrumStaff {

    % the trick with the scaled duration and the shorter rest
