So for now I will use this workaround :
\version "2.25.8"
tempoChange =
#(define-music-function (interval endscale thenscale music)
(ly:duration? scale? (scale? 1) ly:music?)
"Make a gradual tempo change over @var{music}, essentially changing
speed after
every duration of @var{interval},
M(core dumped)WE pretty please :
tempoChange =
#(define-music-function (interval endscale thenscale music)
(ly:duration? scale? (scale? 1) ly:music?)
"Make a gradual tempo change over @var{music}, essentially changing
speed after
every duration of @var{interval}, approaching a factor of
Well, I think my code structure is the problem.
The way I create parts is with this part generator this way :
#(typicalPart 'piccolo piccolo structure)
And for *every* part (instrument) it merges my \structure variable
(\mark, \tempo, i.e. what every body in the orchestra needs) with the
music
Not quite there yet.
Now I get :
warning: the property 'tempoWholesPerMinute' must be of type 'positive
moment with no grace part', ignoring invalid value '#'

And what do you know :
git diff to the rescue.

I tried different avenues and \articulate seems to have creeped its

Silly me :-)

I'm not quite sure how to use it correctly yet but I suppose a typical
usage would be :
\time 6/8 % btw
\tempoChange 8 1/2 0 {
\skip 2.*4 |
}
^ I.e. : To slow down every 8th during 2.*4 to reach (and keep (0)) a
tempo half the speed it was.
I get inconsistent results either :

No, it has worked for at least a year or so here. Probably the usage
example is less
Thank you David. Your code is well above my level for now, but it'll be
great study material. Is it for 2.25.x? I haven't quite got it working yet,
but that's probably my fault.

Thank you Valentin. This is great. Works perfectly and also instructive for
a relative newbie to Scheme.

Hello Adam,
Using #{ ... #} does not magically register the music or something. A scheme
expression such as (begin ...) will evaluate to the last statement. So
(begin #{ ... #} (enact-tempo-decrease ...))
will simply evaluate to the second part, thus always to #{#}.
What you do in fact need
Hello Adam,
your problem is that you are feeding the whole list of tempi into each \tempo
command. Instead you should do something like
myRall =
#(define-music-function
(steps duration)
(integer? ly:duration?)
(let* ((tempi-list (iota steps 100 -1))
(tempi-mus (map (lambda (t) #{
I've given it some more work. The \repeat construct is gone, and the

Hello list,
I'm trying to create a Scheme function that will automatically calculate
and enact a *rall*. as a sequence of \tempo assignments. I am aware of the
basic *rall*., *rit*., and *accel*. functions in "articulate.ly" but I
wanted something I have a little more control over.
I need help,
