... Contrary to some statements here, there is no practical problem in
playing this in JI. The only practical problems concern my fingers, in
particular they somewhat give the game away about 2/3 the way through.

The ratios used will be posted later! I can though reveal that the C#
in the 4th bar (we are in F major now) and the Eb in the
second-to-last were tuned via septimal ratios.

I found it at:

I think there was a typo inTom's message.

Now I know why I used a sequencer to do this in midi;-)

Don't care about your fingers, Tom, the example is beautiful!

At a glance and without any detailed analysis, I seem to spot 2 if not 3
consecutive pure major thirds, and also 3 if not 4 consecutive diatonic pure
fifths: thus this is not 1/4 S.c. meantone neither any modification of it. I
guess it is a variant of just intonation like Ramos (1 flat fifth) or
Agricola's (3 flat fifths), but if indeed pure septimal ratios have been
used this would be a slightly different version.

Kind regards

Was the harpsichord itself JI tuned?

One thing I did notice was that you played a line out of tune, then caught yourself and
replayed it in tune, as if you had played the 7th of the chord with the regular Bb, then
replayed it with an alternate Bb tuned in septimal. Is this the give away you were talking
about?

Yes, of course. I put the ratios in the other GSTQ thread. There is a
G(10/9), and a G(9/8) played on the G# key. No septimal Bb though.

I must make one correction: it seems I got the direction of my
supposedly 'septimal' C# wrong. I must have tuned it as 17/12 above
G=(10/9) instead, i.e. 85/54. As the bass of a dim7 it doesn't have
anything to particularly recommend it.

If it had been 17/12 *below* G=(10/9), i.e. 40/51, then C#-G-Bb would
at least be 1/(10:12:17). But one shouldn't expect dim7s with a
5-limit framework to be consonant anyway.

Strict 5-limit JI with a limited number of keys seems only to start
getting weird or unwelcome sounding when one has mild passing
dissonances that 'ought' to be reasonably in tune with other sounding
tones, but actually involve wolves. E.g. if I wanted to play
bb'-c''-d'' above a chord f-d'-g'. Homophonic chord sequences are much
easier...
