More about pitches

A sharp (#) pitch is made by adding is to the name, a flat (b) pitch by adding es. As you might expect, a double sharp or double flat is made by adding isis or eses:1

     cis1 ees fisis aeses

The key signature is set with the command "\key", followed by a pitch and \major or \minor:

          \key d \major
          g1
          \key c \minor
          g

Key signatures together with the pitch (including alterations) are used together to determine when to print accidentals. This is a feature that often causes confusion to newcomers, so let us explain it in more detail:

LilyPond has a sharp distinction between musical content and layout. The alteration (flat, natural or sharp) of a note is part of the pitch, and is therefore musical content. Whether an accidental (a flat, natural or sharp sign) is a printed in front of the corresponding note is a question of layout. Layout is something that follows rules, so accidentals are printed automatically according to those rules. The pitches in your music are works of art, so they will not be added automatically, and you must enter what you want to hear.

For example, in this example:

[picture of music]

no note gets an explicit accidental, but still you enter

     \key d \major
     d cis fis
     

The code d does not mean "print a black dot just below the staff." Rather, it means: "a note with pitch D-natural." In the key of A-flat, it gets an accidental:

[picture of music]

     \key as \major
     d
     

Adding all alterations explicitly might require some more effort when typing, but the advantage is that transposing is easier, and music can be printed according to different conventions. See Accidentals for some examples how accidentals can be printed according to different rules.

A tie is created by adding a tilde "~" to the first note being tied:

          g4~ g a2~ a4

This example shows the key signature, accidentals and ties in action:

          \score {
            \notes {
              \time 4/4
              \key g \minor
              \clef violin
              r4 r8 a8 gis4 b
              g8 d4.~ d e'8
              fis4 fis8 fis8 eis4  a8 gis~
              gis2 r2
            }
            \paper { }
          }

There are some interesting points to note in this example. Bar lines and beams are drawn automatically. Line breaks are calculated automatically; it does not matter where the lines breaks are in the source file. Finally, the order of time, key and clef changes is not relevant: in the printout, these are ordered according to standard notation conventions.

Beams are drawn automatically, but if you do not like where they are put, they can be entered by hand. Mark the first note to be beamed with [ and the last one with ]:

          a8[ ais] d[ es r d]
