Re: Odd output

[Phil Holmes]

As I replied in my direct reply - because it's not right.  I asked a friend who teaches music about the Mikado problem I had and he said:

 

"Key- C major

Bass note pedals - C-G C-G etc.

Chord in Bar 1 G7 (G B D Fnat = dominant 7th); Chord in Bar 2 C major (CEG)

Each bar has a melody which uses AGF# G with the F# as a chromatical altered
note (lower auxiliary between the 2 Gs) and therefore clashes (to create
interest) with both chords.

Each sounds fine on their own but looks illogical as a whole.

If you can convince LilyPond that the accidentals are in different voices in
the piano part then I would hope it would work.   You could but shouldn't
use a Gb not a F# as the first chordsis a G chord."

Note his final comment - could use a Gb but shouldn't.

Why not set one of the notes to a different enharmonic pitch?  It's certainly much kinder to the musician who's trying to play the composition.

 \include "english.ly"

{

\clef treble

\time 4/4

<<

{ fs'4 }

\\

{ es'4 }

>>

}        

Cheers,
Mike

As is often pointed out, it's free software and the fixes depend on who is working for nothing on the code.

I wouldn't think it would crop up frequently.

I made a workaround with a combination of forcing the accidentals to be displayed, and then using force-hshift and extra-offset and a few other tweaks to make it work.

My example is pretty complicated, because I also autogenerate the code, but you're welcome to a copy if you want.

Thanks!

I can't believe that this is seen as a low priority enhancement...! This
completely renders lilypond unusable for the task I need it, which is to serve
as a printer for computer generated music. The output is not ugly - it is
plain wrong!

Why doesn't the accidental_engraver looks into other voices as well?

Maybe I can workaround it by doing an extra pass before writing the lilypond
code to check if this kind of problem may occur... But now I wonder what other
kind of potential problems may occur with this accidental_engraver
algorithm...

Anyway, I just wanted to say that I think this problem deserves more
consideration.

Thank you!
Marco

This was one of the first issues I raised, in June this year.  I think it
was my first bug report:
