Re: Anchor points of Slurs / Phrasing slurs

[Valentin Petzel]

Thank you, Valentin. I stumbled upon this snipped a while before, and it’s 
really useful for shaping more complex slurs. Still, it’s not what I’m after, 
I’m trying to experiment, if Lilypond can find some of the more complex slur 
shapes. But for this, I have to work around the limitation that lilypond’s 
spanner-design imposes on slurs.

I’m planning to do some documentation on how you can actually use this for 
nice slurs, but for now I’ve created an example demonstrating why this does 
matter. Please take a look at the last page, it’s a comparisation of the 
shapeII-placed example from your linked post and an automatically placed one 
with two little overrides. This page demonstrates that good manual placement 
requires lots of knowledge and work, and should therefore be avoided if 
possible. If you print it out, you will see that the manually placed slurs 
actually have too uneven and too much distance from the note heads, thereby 
distracting from the actual music.

Best regards,
Valentin
