RE: multiple tempi in a single piece

[Trevor Daniels]

Hi Kieran

The following shows how I change the Midi tempi - you can
easily adapt this example to do what you want:

TempiA= {
 \override Score.MetronomeMark #'padding = #3.0
 %Page 1 System 1 Bar 1
 \tempo 2=80 s1 | s | s | s | s | s | s |
 %Page 1 System 2 Bar 8
 % the following tempo changes implement the fermata in bar
9
 \override Score.MetronomeMark #'transparent = ##t % hide
the marks
 s1 | \tempo 2=50 s | \tempo 2=80 s | s1 | s | s | s | s | s
|
 %Page 1 System 3 Bar 17
 % the following tempo changes implement the fermata in bar
18
 s1 | \tempo 2=50 s | \tempo 2=80 s | s | s | s | s | s |
}

I simply insert this in parallel with the music.

Hi everyone,

I am sure there is a way to do this, but maybe someone here
has already faced this challenge and can help show me how it
can be done.

My example is the Bach Sinfonia from Partita #2. It has a
Grave, Andante, and Allegro, but the MIDI file plays all the
sections at the same speed, 120bpm. I am looking for a way
to modify the .ly file so that it generats a MIDI file that
plays the Grave at say 40bpm, the Andante at 80bpm, and only
the Allegro at 120bpm.

I would greatly appreciate any help to discover how to do
this!

Thanks,

Kieran Coulter
