The LilyPond Snippet Repository ♪♫

If you want to add notes to the existing notes of a melody (to make chords), you generally have to copy your melody then add lots of <_ to="to" each="each" note="note" which="which" can="can" be="be" a="a" time-consuming.p="time-consuming.p"> The \addNote function here makes it faster and simpler.

The syntax is : \addNote \melody \newNotes

Here :

melody = \relative {c'4.-> d8-. c4(\p b8) r c4\f c c2}

newnotes = {e f e d e s e}



Note that with this function, you can easily create some other useful functions. For example, a function \doubleOctave is shown here. This doubles each note with the note an octave higher.

This shows one approach to simplify adding many orchestral cues to the piano reduction in a vocal score. The music function \cueWhile takes four arguments: the music from which the cue is to be taken, as defined by \addQuote, the name to be inserted before the cue notes, then either #UP or #DOWN to specify either \voiceOne with the name above the staff or \voiceTwo with the name below the staff, and finally the piano music in parallel with which the cue notes are to appear. The name of the cued instrument is positioned to the left of the cued notes. Many passages can be cued, but they cannot overlap each other in time.

The \parenthesize function is a special tweak that encloses objects in parentheses. The associated grob is ParenthesesItem.

Punctuation can be added to the end of an extender in melismata by overriding the default stencil for LyricExtender.

For convenience, this snippet applies the stencil override as a tweak to the extender event.

Rests are entered like notes, with the note name r, so just type r followed by the duration.

With a little Scheme code, the current date can easily be added to a score.

There are a couple ways to get the current date in your score - using Scheme and a header that suits you (as you may find in the Adding the current date to a score example), or placing the same Scheme code in a \markup block.

One more option is to place the date in the tagline. This places the date at the bottom of the last page and appears like this -

The format of the date can be changed according to these parameters:

• %a - is replaced by the locale's abbreviated weekday name.
• %A - is replaced by the locale's full weekday name.
• %b - is replaced by the locale's abbreviated month name.
• %B - is replaced by the locale's full month name.
• %c - is replaced by the locale's appropriate date and time representation.
• %d - is replaced by the day of the month as a decimal number [01,31].
• %I - is replaced by the hour (12-hour clock) as a decimal number [01,12].
• %j - is replaced by the day of the year as a decimal number [001,366].
• %m - is replaced by the month as a decimal number [01,12].
• %M - is replaced by the minute as a decimal number [00,59].
• %p - is replaced by the locale's equivalent of either a.m. or p.m.
• %U - is replaced by the week number of the year (Sunday as the first day of the week) as a decimal number [00,53].
• %w - is replaced by the weekday as a decimal number [0,6], with 0 representing Sunday.
• %W - is replaced by the week number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday are considered to be in week 0.
• %x - is replaced by the locale's appropriate date representation.
• %X - is replaced by the locale's appropriate time representation.
• %y - is replaced by the year without century as a decimal number [00,99].
• %Y - is replaced by the year with century as a decimal number.
• %Z - is replaced by the timezone name or abbreviation, or by no bytes if no timezone information exists.

Skipped beats in very long glissandi are sometimes indicated by timing marks, often consisting of stems without noteheads. Such stems can also be used to carry intermediate expression markings.

If the stems do not align well with the glissando, they may need to be repositioned slightly.

The Volta_engraver by default resides in the Score context, and brackets for the repeat are thus normally only printed over the topmost staff. This can be adjusted by adding the Volta_engraver to the Staff context where the brackets should appear; see also the Volta multi staff snippet.

In some instances of complex polyphonic music, additional voices are necessary to prevent collisions between notes. If more than four parallel voices are needed, additional voices can be added by defining a variable using the Scheme function context-spec-music.
