Hello!
After some time I had a look to Solfege again and tried out some csound based
intonation exercises. It is a ver-very important issue and really great that
the exercises are there!
I wrote it also to bug-repports (not really a bug though) but i write it also
to the mailing-list, if anybody is busy writing new lesson files:
I recommend to use a waveform (f-statement) with more harmonics in csound
lessonfiles for intonation, especially in case of harmonic intervals:
Instead of:
f1 0 4096 10 1 ; use GEN10 to compute a sine wave
use
f1 0 4096 10 1 1.25 0.95 0.8 0.6 0.4 0.2 ; sine wave with 6 overtones
or similar. You can experiment with the ratio and number of the harmonics.
Why? - Two simultanously sounding notes are in tune when their harmonics
coinside as much as possible. Otherwise you will hear the so called beating or
pulsation. So it makes actually very little sense if the signal is just sine
waves with no harmonics (as it is now). In reality, of course, there is no TRUE
sine tone because all loudspeakers and also our ears add harmonics so we can
still decide. But if we add the harmonics to the waveform (and it is so easy
with csound!), making difference is so much easier!
Have a look at http://code.google.com/p/solfege/issues/detail?id=137&q=csound
for some examples.
greetings!

PS maybe the waveform I suggested is not the most beautiful one. It is
something like flute but I did not take much care.. If yoy want me, I can
experiment to find more musical one!
