source file: mills2.txt Date: Thu, 24 Apr 1997 15:45:10 -0700 Subject: Guitar fretting From: clucy@cix.compulink.co.uk (Charles Lucy) As the tuning discussion seems to have turned to guitar fretting, you may be interested to see how I tackled this question. My intention was to make converting from 12tET as easy as possible for experienced guitarists. (Hence the dots etc.) I propose that newbies first fret their instrument with 19, and later (when ready) add another 12 to give a total of 31 frets per octave. The second octave works better using mandolin fretting wire. The close frets are activated by playing ON the pair, to sound the sharper note; and BELOW the pair for the flatter. You'll notice that the sharper of the pair is always a sharp, and the flatter of the pair always a flat. Fret positions for LucyTuned 19 & 31 frets per octave instruments.
