Re: "note equals note" or durational equivalent

[Paul Scott]

Here is my version which I keep in an include file of common definitions I use:

#(define-markup-command (eqBeat layout props notetypeL notetypeR)
  (ly:duration? ly:duration?)
  (interpret-markup layout props
   (markup
    #:tiny #:raise 0.4 (#:note notetypeL up)
    #:tiny "="
    #:tiny #:raise 0.4 (#:note notetypeR up)
  )))

used as

\markup{ \eqBeat {4} {8} }

textMark \markup{ \eqBeat {4} {8} }

I can give you a similar definition which includes a tempo number if you want.

HTH,

Paul

Dear Lilypond

I am trying to add a "note value equals note value" in the middle of a piece.  

I would call this a "durational equivalent" or a "beat unit equivalent".  

Lilypond must have a different name for it, however, because I can not find this by searching.  

The closest I can find is Lilypond's "Music Notation inside Markup",  which is what i want, but i can not get the code to work.  Cutting and pasting the following from the Lilypond Notation Reference will work: 

^\markup {  

\note {4} #1 

=  

\note-by-number #1 #1 #1.5 

}

but i do not understand the syntax.  This results in "quarter-note = dotted-half-note with a long stem".

What do the various # signs control? I get errors whenever i try to change any of them. 

FYI, I am trying to write "half note = half note", and scale it to about 75% size.  

Again, this is to go in the middle of the piece, not in the tempo / metronome field at the beginning of the piece.

Dirck,

A tempo/ metronome doesn’t have to appear at the beginning of a piece, it can be perfectly positioned in the middle of a piece like so are you sure what you’re after is not a tempo marking?

\version "2.24.0"

{

    c' c' c' c'

    \tempo \markup {

    \rhythm { c4 } = \rhythm { c4 }

    }

    c' c' c' c'

}

Note: I had to add an explicit pitch as lilypond didn’t interpret a plain 4 as music yielding

error: wrong type for argument 1.  Expecting music, found (ly:make-duration 2)

    \rhythm 

            { 4 } = \rhythm { 4 }

without it
