Quote: Originally posted by fernandraynaud | ...I have been tuning my ouds using my Korg OT-120 set to Vallotti, since I use that preset for harpsichord. For the notes we care about, C, D, G, A
and in my case a low E instead of an F, Vallotti is the same as meantone, i.e. these are perfect 3:2 intervals. With the A being the same 440, the C
strings in particular are markedly different from ET, like almost 15 cents sharper, but D and G are different too, and with the open strings tuned
this way I DO get the perfect fourths/fifths I might get by nulling out beats if I could hear them, and the oud sounds much better to me than using ET
intervals. Of course that's just on open strings, but it also affects sympathetic resonance, and I don't think it's insignificant.

Since strings are in fourths, they should be pure 4:3 intervals.
I'm confused somewhat by your statements, because with pure fourths, the C should be flatter , not sharper, than ET. An ET P5 is 2 cents
flatter than a pure 3:2 5th, thus an ET 4th is 2 cents sharper than a pure 4:3 4th.
If A is the reference, then C should be 6 cents flat relative to ET. 15 cents sharper than ET is actually 21 cents sharper and the pure interval,
which is far more offensive than ET's being 6 cents sharp.
As I said before, the Arab standard is to use G as a reference, which makes the D and C each 2 cents off relative to ET, and the A 4 cents off.
