1.1.1 Writing pitches
This section discusses how to input pitches. There are two different ways to place notes in octaves: absolute and relative mode. In most cases, relative mode will be more convenient.

Absolute octave entry
A pitch name is specified using lowercase letters a
through g
. The note names c
to b
are
engraved in the octave below middle C.
\clef bass c d e f g a b c d e f g
Other octaves may be specified with a single quote ('
)
or comma (,
) character. Each '
raises the
pitch by one octave; each ,
lowers the pitch by an
octave.
\clef treble c' c'' e' g d'' d' d c \clef bass c, c,, e, g d,, d, d c

Relative octave entry
When octaves are specified in absolute mode it is easy to accidentally put a pitch in the wrong octave. Relative octave mode reduces these errors since most of the time it is not necessary to indicate any octaves at all. Furthermore, in absolute mode a single mistake may be difficult to spot, while in relative mode a single error puts the rest of the piece off by one octave.
\relative startpitch musicexpr
In relative mode, each note is assumed to be as close to the previous note as possible. This means that the octave of each pitch inside musicexpr is calculated as follows:
- If no octave changing mark is used on a pitch, its octave is calculated so that the interval with the previous note is less than a fifth. This interval is determined without considering accidentals.
-
An octave changing mark
'
or,
can be added to respectively raise or lower a pitch by an extra octave, relative to the pitch calculated without an octave mark. -
Multiple octave changing marks can be used. For example,
''
and,,
will alter the pitch by two octaves. -
The pitch of the first note is relative to
startpitch
. startpitch is specified in absolute octave mode, and it is recommended that it be a octave ofc
.
Here is the relative mode shown in action:
\relative c { \clef bass c d e f g a b c d e f g }
Octave changing marks are used for intervals greater than a fourth:
\relative c'' { c g c f, c' a, e'' c }
A note sequence without a single octave mark can nevertheless span large intervals:
\relative c { c f b e a d g c }
If the preceding item is a chord, the first note of the chord is
used as the reference point for the octave placement of a
following note or chord. Inside chords, the next note is always
relative to the preceding one. Examine the next example
carefully, paying attention to the c
notes.
\relative c' { c <c e g> <c' e g'> <c, e, g''> }
As explained above, the octave of pitches is calculated only with the note names, regardless of any alterations. Therefore, an E-double-sharp following a B will be placed higher, while an F-double-flat will be placed lower. In other words, a double-augmented fourth is considered a smaller interval than a double-diminished fifth, regardless of the number of semitones that each interval contains.
\relative c'' { c2 fis c2 ges b2 eisis b2 feses }

Known issues and warnings
The relative conversion will not affect \transpose
,
\chordmode
or \relative
sections in its argument.
To use relative mode within transposed music, an additional
\relative
must be placed inside \transpose
.
If no startpitch is specified for \relative
,
then c'
is assumed. However, this is a deprecated
option and may disappear in future versions, so its use is
discouraged.

Accidentals
Note: New users are sometimes confused about accidentals and
key signatures. In LilyPond, note names are the raw input; key
signatures and clefs determine how this raw input is displayed.
An unaltered note like |
A sharp pitch is made by adding is
to the note
name, and a flat pitch by adding es
. As you
might expect, a double sharp or double flat
is made by adding isis
or eses
. This syntax is
derived from Dutch note naming conventions. To use other names
for accidentals, see Note names in other languages.
ais1 aes aisis aeses
A natural will cancel the effect of an accidental or key signature. However, naturals are not encoded into the note name syntax with a suffix; a natural pitch is shown as a simple note name:
a4 aes a2
Quarter tones may be added; the following is a series of Cs with increasing pitches:
ceseh1 ces ceh c cih cis cisih
Normally accidentals are printed automatically, but you may also
print them manually. A reminder accidental can be forced by
adding an exclamation mark !
after the pitch. A
cautionary accidental (i.e., an accidental within parentheses) can
be obtained by adding the question mark ?
after the
pitch. These extra accidentals can also be used to produce
natural signs.
cis cis cis! cis? c c c! c?
Accidentals on tied notes are only printed at the beginning of a new system:
cis1 ~ cis ~ \break cis
Selected Snippets
Preventing extra naturals from being automatically added
In accordance with standard typesetting rules, a natural sign is
printed before a sharp or flat if a previous accidental on the same
note needs to be canceled. To change this behavior, set the
extraNatural
property to "false" in the Staff
context.
\relative c'' { aeses4 aes ais a \set Staff.extraNatural = ##f aeses4 aes ais a }
Makam example
Makam is a type of melody from Turkey using 1/9th-tone
microtonal alterations. Consult the initialization file
makam.ly
(see the ‘Learning Manual 2.12.2,
4.6.3 Other sources of information’ for the location of this file)
for details of pitch names and alterations.
% Initialize makam settings \include "makam.ly" \relative c' { \set Staff.keySignature = #`((3 . ,BAKIYE) (6 . ,(- KOMA))) c4 cc db fk gbm4 gfc gfb efk fk4 db cc c }

Known issues and warnings
There are no generally accepted standards for denoting quarter-tone accidentals, so LilyPond’s symbol does not conform to any standard.

Note names in other languages
There are predefined sets of note and accidental names for various
other languages. To use them, include the language-specific init
file listed below. For example, to use English notes names, add
\include "english.ly"
to the top of the input file.
The available language files and the note names they define are:

In Dutch, aes
is contracted to as
, but both forms
are accepted in LilyPond. Similarly, both es
and
ees
are accepted. This also applies to
aeses
/ ases
and
eeses
/ eses
. Sometimes only these
contracted names are defined in the corresponding language files.
a2 as e es a ases e eses
Some music uses microtones whose alterations are fractions of a ‘normal’ sharp or flat. The note names for quarter-tones defined in the various language files are listed in the following table. Here the prefixes semi- and sesqui- mean ‘half’ and ‘one and a half’, respectively. For the other languages, no special names have been defined yet.
