Re: fingering

[Gianmaria Lari]

I found some solution that I post here to get some feedback and/or other suggestions.

Here they are 4 different ways to add fingering to a musical _expression_:

1 Standard:

\version "2.21.0"

\fixed c' {a-1 c' f'-\finger\markup\circle 3 a'-4}

2 Different context (thanks Pierre Perol-Schneider for your help!):

\version "2.21.0"

<<

  \new Dynamics \with { \consists Fingering_engraver } {s-1 s s-\finger\markup\circle 3 s-4}

  \new Staff \fixed c' {a c' f' a'}

>>

3 Multiple voices (please correct me if my terminology is not correct!):

\version "2.21.0"

\new Voice {

  <<

    { s-1 s s-\finger\markup\circle 3 s-4}

    \fixed c'{ a c' f' a' }

  >>

}

4 addFingering

\version "2.21.0"  

\include "addFingering.ly"

\addStringNumber \addFingering \fixed c'{a c' f' a'} "1xx4" "xx3x"

The engraved results are the same except for example 2 where the output is less pleasant because fingering doesn't follow the flow of the notes.

The solution 4 is a bit special because I used the addFingering external function (thanks Gilles Thibault!).

Let me discuss a bit about solution 3. 

Here it is:

\version "2.21.0"

\new Voice {

  <<

    { s-1 s s-\finger\markup\circle 3 s-4}

    \fixed c'{ a c' f' a' }

  >>

}

I rewrite it using variables:

\version "2.21.0"

myMusic = \fixed c'{ a c' f' a' }

myFing = { s-1 s s-\finger\markup\circle 3 s-4}

\new Voice << \myMusic \myFing  >>

Now lets me compare it with the standard solution:

\fixed c' {a-1 c' f'-\finger\markup\circle 3 a'-4} 

If I'm not wrong to generate the two variables (myMusic and myFing) from the previous code should not be that difficult.

1 I duplicate the music _expression_

2 In the variable where I want to put the music I remove the fingering

3 In the variable where I want to put the fingering I remove all the articulations and I substitute each note occurrence with their octave with s.

In frescobaldi there is already a snippet to remove fingering and remove many type of articulations. And to substitute each note occurrence with 's' a regex _expression_ should do it pretty easily.

Any comments?

Thank you, g.
