+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

+@code{c'} is used as the default if no starting pitch is defined.
-Whole bar rests, centered in middle of the bar,
-must be done with multi-measure rests. They can be used for a
-single bar as well as many bars, and are discussed in
-@ref{Multi measure rests}.
+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.
-To explicitly specify a rest's vertical position, write a note
-followed by @code{\rest}. A rest will be placed in the position
-where the note would appear,
+The octave changing marks @code{'} and @code{,} can be added to raise

+@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

+\new Staff {
+ \clef "F" \mus
+ \clef "G"
+ \transpose c g' \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{} @} @}

-@cindex polyphony
-
-The easiest way to enter fragments with more than one voice on a staff
-is to enter each voice as a sequence (with @code{@{...@}}), and combine
-them simultaneously, separating the voices with @code{\\}
-
-@cindex @code{\\}

-
-The separator causes @internalsref{Voice} contexts@footnote{Polyphonic
-voices are sometimes called ``layers'' in other notation packages}
-@cindex layers
-to be instantiated. They bear the names @code{"1"}, @code{"2"}, etc. In
-each of these contexts, vertical direction of slurs, stems, etc., is set
-appropriately.
-
-These voices are all separate from the voice that contains the notes just
-outside the @code{<< \\ >>} construct. This should be noted when making
-changes at the voice level. This also means that slurs and ties cannot go
-into or out of a @code{<< \\ >>} construct. Conversely, parallel voices
-from separate @code{<< \\ >>} constructs on the same staff are the the
-same voice. Here is the same example, with different noteheads for each
-voice. Note that the change to the note-head style in the main voice does not affect
-the inside of the @code{<< \\ >>} constructs. Also, the change to the second
-voice in the first @code{<< \\ >>} construct is effective in the second
-@code{<< \\ >>}, and the voice is tied across the two constructs.

-Polyphony does not change the relationship of notes within a

-to the note immediately preceding it.
-
-@example

-@end example
-
-@code{noteC} is relative to @code{noteB}, not @code{noteA};

-@node Explicitly instantiating voices
-@subsection Explicitly instantiating voices
-
-@internalsref{Voice} contexts can also be instantiated manually
-inside a @code{<< >>} block to create polyphonic music, using
-@code{\voiceOne}, up to @code{\voiceFour} to assign stem directions
-and a horizontal shift for each part.
-
-Specifically,
-@example
-<< \upper \\ \lower >>
-@end example
-
-@noindent
-is equivalent to
-
-@example
-<<
- \new Voice = "1" @{ \voiceOne \upper @}
- \new Voice = "2" @{ \voiceTwo \lower @}
->>
-@end example
-
-The @code{\voiceXXX} commands set the direction of stems, slurs, ties,
-articulations, text annotations, augmentation dots of dotted
-notes, and fingerings. @code{\voiceOne} and @code{\voiceThree} make
-these objects point upwards, while @code{\voiceTwo} and @code{\voiceFour}
-make them point downwards.
-The command @code{\oneVoice} will revert back to the normal setting.
-
-An expression that appears directly inside a @code{<< >>} belongs to
-the main voice. This is useful when extra voices appear while the main
-voice is playing. Here is a more correct rendition of the example from
-the previous section. The crossed noteheads demonstrate that the main
-melody is now in a single voice context.

bracket only lasts one measure, which is a duration of 3/4.
