In any tempered fretting system that's been worked out properly you
need to first set the frets, then tune the strings to each other in
perfect octaves or unisons, since these intervals must be pure in all schemes.

If you insist on all unisons and all octaves being pure you have no choice - 
you must use equal temperament.

This is a straight forward calculation in linear algebra.

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).

2008-10-04 Thread Martyn Hodgson

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.

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...

2008-10-04 Thread Sam Chapman
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?

All the best,

Sam

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.
This is my basic understanding - I'm sure someone on this list will
know better/more...

2008-10-03 Thread William Brohinsky
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.

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. Any ideas where I went wrong?

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!
