The key signature indicates the tonality in which a piece is played. It is denoted by a set of alterations (flats or sharps) at the start of the staff.
Setting or changing the key signature is done with the \key
command
\key
pitch type
Here, type should be \major
or \minor
to get
pitch-major or pitch-minor, respectively.
The standard mode names \ionian
,
\locrian
, \aeolian
, \mixolydian
, \lydian
,
\phrygian
, and \dorian
are also defined.
This command sets the context property
Staff (lilypond-internals)
.keySignature
. Non-standard key signatures
can be specified by setting this property directly.
A natural sign is printed to cancel any previous accidentals. This
can be suppressed by setting the Staff.printKeyCancellation
property.
{ \key d \major a b cis d \key g \minor a bes c d \set Staff.printKeyCancellation = ##f \key d \major a b cis d \key g \minor a bes c d }
Accidentals and key signatures often confuse new users, because unaltered notes get natural signs depending on the key signature. For more information, see More about pitches.
