-@cindex Relative
-@cindex Relative octave specification
-@funindex \relative
-
-Octaves are specified by adding @code{'} and @code{,} to pitch names.
-When you copy existing music, it is easy to accidentally put a pitch
-in the wrong octave and hard to find such an error. The relative
-octave mode prevents these errors by making the mistakes much
-larger: a single error puts the rest of the piece off by one octave
-
-@example
-\relative @var{startpitch} @var{musicexpr}
-@end example
-
-@noindent
-or
-
-@example
-\relative @var{musicexpr}
-@end example
-
-@noindent
-@code{c'} is used as the default if no starting pitch is defined.
-
-The octave of notes that appear in @var{musicexpr} are calculated as
-follows: if no octave changing marks are used, the basic interval
-between this and the last note is always taken to be a fourth or
-less. This distance is determined without regarding alterations; a
-@code{fisis} following a @code{ceses} will be put above the
-@code{ceses}. In other words, a doubly-augmented fourth is considered
-a smaller interval than a diminished fifth, even though the
-doubly-augmented fourth spans seven semitones while the diminished
-fifth only spans six semitones.
-
-The octave changing marks @code{'} and @code{,} can be added to raise
-or lower the pitch by an extra octave. Upon entering relative mode,
-an absolute starting pitch can be specified that will act as the
-predecessor of the first note of @var{musicexpr}. If no starting pitch
-is specified, then middle C is used as a start.
-
-Here is the relative mode shown in action
-@lilypond[quote,fragment,ragged-right,verbatim]
-\relative c'' {
- b c d c b c bes a
-}
-@end lilypond
-
-Octave changing marks are used for intervals greater than a fourth
-
-@lilypond[quote,ragged-right,fragment,verbatim]
-\relative c'' {
- c g c f, c' a, e''
-}
-@end lilypond
-
-If the preceding item is a chord, the first note of the chord is used
-to determine the first note of the next chord
-
-@lilypond[quote,ragged-right,fragment,verbatim]
-\relative c' {
- c <c e g>
- <c' e g>
- <c, e' g>
-}
-@end lilypond
-
-The pitch after @code{\relative} contains a note name.
-
-The relative conversion will not affect @code{\transpose},
-@code{\chordmode} or @code{\relative} sections in its argument. To use
-relative within transposed music, an additional @code{\relative} must
-be placed inside @code{\transpose}.
-
-
-@anchor{Octave check}
-@unnumberedsubsubsec Octave check
-
-@cindex Octave check
-
-Octave checks make octave errors easier to correct: a note may be
-followed by @code{=}@var{quotes} which indicates what its absolute
-octave should be. In the following example,
-
-@example
-\relative c'' @{ c='' b=' d,='' @}
-@end example
-
-@noindent
-the @code{d} will generate a warning, because a @code{d''} is expected
-(because @code{b'} to @code{d''} is only a third), but a @code{d'} is
-found. In the output, the octave is corrected to be a @code{d''} and
-the next note is calculated relative to @code{d''} instead of @code{d'}.
-
-There is also an octave check that produces no visible output. The syntax
-
-@example
-\octave @var{pitch}
-@end example
-
-This checks that @var{pitch} (without quotes) yields @var{pitch} (with
-quotes) in @code{\relative} mode compared to the note given in the
-@code{\relative} command. If not, a warning is printed, and the
-octave is corrected. The @var{pitch} is not printed as a note.
-
-In the example below, the first check passes without incident, since
-the @code{e} (in @code{relative} mode) is within a fifth of
-@code{a'}. However,
-the second check produces a warning, since the @code{e} is not within
-a fifth of @code{b'}. The warning message is printed, and the octave
-is adjusted so that the following notes are in the correct octave
-once again.
-
-@example
-\relative c' @{
- e
- \octave a'
- \octave b'
-@}
-@end example
-
-
-The octave of a note following an octave check is determined with
-respect to the note preceding it. In the next fragment, the last note
-is an @code{a'}, above middle C. That means that the @code{\octave}
-check passes successfully, so the check could be deleted without changing
-the output of the piece.

-@anchor{Transpose}
-@unnumberedsubsubsec Transpose
-
-@cindex Transpose
-@cindex Transposition of pitches
-@funindex \transpose
-
-A music expression can be transposed with @code{\transpose}. The
-syntax is
-@example
-\transpose @var{from} @var{to} @var{musicexpr}
-@end example
-
-This means that @var{musicexpr} is transposed by the interval between
-the pitches @var{from} and @var{to}: any note with pitch @code{from}
-is changed to @code{to}.
-
-For example, consider a piece written in the key of D-major. If
-this piece is a little too low for its performer, it can be
-transposed up to E-major with
-@example
-\transpose d e @dots{}
-@end example
-
-Consider a part written for violin (a C instrument). If
-this part is to be played on the A clarinet (for which an
-A is notated as a C, and which sounds a minor third lower
-than notated), the following
-transposition will produce the appropriate part
-
-@example
-\transpose a c @dots{}
-@end example
-
-@code{\transpose} distinguishes between enharmonic pitches: both
-@code{\transpose c cis} or @code{\transpose c des} will transpose up
-half a tone. The first version will print sharps and the second
-version will print flats
-
-@lilypond[quote,ragged-right,verbatim]
-mus = { \key d \major cis d fis g }
-\new Staff {
- \clef "F" \mus
- \clef "G"
- \transpose c g' \mus
- \transpose c f' \mus
-}
-@end lilypond
-
-@code{\transpose} may also be used to input written notes for a
-transposing instrument. Pitches are normally entered into LilyPond
-in C (or @q{concert pitch}), but they may be entered in another
-key. For example, when entering music for a B-flat trumpet which
-begins on concert D, one would write
-
-@example
-\transpose c bes @{ e4 @dots{} @}
-@end example
-
-To print this music in B-flat again (i.e., producing a trumpet part,
-instead of a concert pitch conductor's score) you would wrap the
-existing music with another @code{transpose}
-
-@example
-\transpose bes c @{ \transpose c bes @{ e4 @dots{} @} @}
-@end example
-

-@seealso
-
-Program reference: @internalsref{TransposedMusic}.
-
-Example: @lsr{scheme,transpose-pitches-with-minimum-accidentals.ly}.
-
-
-@refbugs
-
-If you want to use both @code{\transpose} and @code{\relative},
-you must put @code{\transpose} outside of @code{\relative}, since
-@code{\relative} will have no effect on music that appears inside a
-@code{\transpose}.

-@cindex transposition, MIDI
-@cindex transposition, instrument
-
-The key of a transposing instrument can also be specified. This
-applies to many wind instruments, for example, clarinets (B-flat, A, and
-E-flat), horn (F) and trumpet (B-flat, C, D, and E-flat).
-
-The transposition is entered after the keyword @code{\transposition}
-
-@example
-\transposition bes %% B-flat clarinet
-@end example
-
-@noindent
-This command sets the property @code{instrumentTransposition}. The value of
-this property is used for MIDI output and quotations. It does not
-affect how notes are printed in the current staff. To change the printed
-output, see @ref{Transpose}.
-
-The pitch to use for @code{\transposition} should correspond to the
-real sound heard when a @code{c'} written on the staff is played by the
-transposing instrument. For example, when entering a score in
-concert pitch, typically all voices are entered in C, so
-they should be entered as
-
-@example
-clarinet = @{
- \transposition c'
- ...
-@}
-saxophone = @{
- \transposition c'
- ...
-@}
-@end example
-
-The command @code{\transposition} should be used when the music is
-entered from a (transposed) orchestral part. For example, in
-classical horn parts, the tuning of the instrument is often changed
-during a piece. When copying the notes from the part, use
-@code{\transposition}, e.g.,
-
-@example
-\transposition d'
-c'4^"in D"
-...
-\transposition g'
-c'4^"in G"
-...
