You're right, Rainer - but just in case there's any misunderstanding: In a meantone temperament you don't expect all the apparent octaves to be pure, for example the Gb on the first fret (high position) of the 4th course with the F# on the fourth fret (low position) of the 2nd course - this is just a consequence of having frets which are straight and cannot be in different positions on different courses. You still expect the proper octaves to be pure, such as 2nd fret 4th course with open 1st course. Anyone using meantone fretting has to be aware of the limitations and test only some octaves and not others (and move frets according to the notes required by the piece).

[LUTE] Re: Temperament wondering...
Just so Martin. The principal problem with meantone on fretted instruments has often been raised before but it's always as well to repeat it for those new to the issue: If the diatonic and chromatic sequence between frets as one ascends the fingerboard were the same on each string then meantone fretting could indeed by applied, but since this is not the case then, as you say, a number of significant compromises have to be made. These compromises are, of course, less if one stays in certain positions and and the music does not modulate very far from the tonic.

[LUTE] Re: Temperament wondering...
You're right - it's not a circular process if the fretting system has been worked out properly. As I said, I've been using David van Ooijen's instructions for tuning in 1/6 comma and it's a straight- forward process. But I was referring to the historical instructions found on the LSA Fret Placement Chart, which (no disrespect to the Ancients) haven't been passed down to us 100% accurately. So there's some to-ing and fro-ing between frets and open strings to figure out that Gerle, for instance, was aiming at approx. 1/6 comma. Obviously, having established this, I don't need to repeat the process - I can just tune straight to 1/6 comma...

[LUTE] Re: Temperament wondering...
Ah...I see what you mean Andrew! In reply to Rainer, Martin and Martyn: perhaps I'm being incredibly naive, but I've always managed to tune octaves and unisons on my theorbo with no beating, whether or not I set the frets equal or to some variety of meantone. Of course I don't count, for example, g-sharp to a-flat as an octave or unison. I simply stick on tastino if I need a different note, or use alternate fingerings if I'm playing continuo. Do you really suggest that one should tune, for example, the 6th course so that it beats with the 1st and 13th when using temperaments other than equal? Perhaps we misunderstood each other?

The LSA file works on my mac - but I found those historical instructions for placing frets weren't really that useful - I think some are inaccurate (Dowland's doesn't seem to make much sense). And there's no instructions on how to tune the open strings - so if you don't know what temperament you're aiming for, it makes the process a bit circular - tweak the frets, tweak the open strings, tweak the frets etc My basic understanding is that 16th c lute players would have used some kind of meantone - ranging from 1/4 to 1/8 - but of course wouldn't have used that terminology as the fine maths weren't worked out until later when meantone was on the point of becoming obsolete.

[LUTE] Re: Temperament wondering...
Actually, Dowland's tuning is quite sensible. The rule of 18 sets a lute (in theory, neglecting string stretch caused by sideways displacement at the finger and fret) to very-nearly equal temperament. Apparently, the stretch added by actually fingering the strings brings it very very close. This isn't too hard to understand if you look at the math. ET12 is based on each higher semitone frequency being in a ratio of the 12th root of 2 to the previous frequency. From A=440, this is about 440*1.0594631 =466.163761 (using 20 digits for the multiplication and throwing away the seventh decimal on: even still, with 7 decimals, the answer to six decimals is .03 higher!) The rule of 18 uses a ratio of 1+1/18 =.055keep repeating 5's forever, and the result of multiplying this times 440 is 464.4repeating 4's. The percentage of error here is on the order of -.36%. It is not hard to raise the pitch of a string by 1/300th of its current frequency with sidestretching. The error is cumulative, because each subsequent fret is set to (1+1/18)^fret#, but the string is not parallel to the frets (unless you are very lucky) which probably adds stretch, but also the side-stretch caused frequency increase decreases as you approach the middle of the string, which probably nullifies the effect, so the highest frets will be off by as much as 7*-.36, or about 2.4%. This is worth a bit of fudging, but the fifths are already flat from pure, and this amount of difference may not be significant. The rule-of-18 ratio for the fifth is 1.45005 (rounded to five decimals) while the ET12 fifth ratio is 1.49831 (again, to rounded to five decimals.) The just intonated fifth is 1/5. This makes rule-of-18 fifths over A=220, before figuring string stretch modifications, 321.211Hz, ET12 is 329.62Hz, and just is 330Hz. Does anyone have good data on frequency deviation caused by string stretch on a Dowland-era 8-course (for instance) lute? As I have mentioned before, at least to my ear, Dowland's and Holborne's music sounds very good with rule-of-18 fret placement, even without modification. (Then again, the lutes I have been able to play have all had the action a bit too high.) It doesn't seem to work so well for other composers, though.

[LUTE] Re: Temperament wondering...
That does sound sensible - and ingenious - but from recollection, the measurements given by the LSA chart for Dowland's lute gave a narrow distance between the second and third frets, which didn't sound much like ET to me - and generally didn't seem to produce a pattern of proportionally reduced distances between the frets that I imagine you would get from such a system.

[LUTE] Re: Temperament wondering...
OK, I'm stupid this week. Sorry. Rule of 18 is from Vincenzo Galilei and predates the Varietie of Lute lessons. I'll check dowland's tuning when I get home and see if I can make sense of it as well. Interestingly, Doctor Oakroot remarked on possible inaccuracies in Dowland's tuning instructions in this list in April of 2006: it might be instructive to pursue that thread, in the mean time!
