source file: m1543.txt Date: Sat, 03 Oct 1998 14:57:34 PDT Subject: Just (about) Guitar Fretboard by Robin Perry From: "Robin Perry" I have designed and had my guitar re-fretted according to the system described here. I used a method that involves increments of +/- 15 cents to arrive at fret widths and tuning. The Frets: The standard fret width on the guitar is 100 cents. Mine has a repeating 7 fret pattern that goes like this: N} U} 70-115-85-115-115-85-115-70-115-85-115-115-85-115......to 24th fret T} * * Every seven frets is 700 cents due to the repetition. From any fret, you can move up the neck to create either a 1/2/5 or 1/4/5 type progression (in some cases, both.) Depending on how it's tuned, you can also use different fingering patterns to hit inversions and find other progressions. I have experimented with several tunings - starting with an open justabout 4,5,6,7,8,10 - but am currently tuned as follows: 1470 E F-- F#- G-- G#- A Bb- B C-- (successive 1200 C#++ D D#+ E E#+ F#++ G+ G#++ A frets are 885 A#+ B- B# C#- D D#+ E E#+ F#- 3/2(-2c) 700 G#++ A A#+ B B#+ C#++ D+ D#++ E of the fret 270 E F-- F#- G-- G#- A Bb- B C-- 7 frets back) 0 C#++ D D#+ E E#= F#++ G+ G#++ A ------------------------------------------------------------- 0 70 185 270 385 500 585 700 770 With the high string tuned to "E", the tuning is an inversion of an F#++ 9 chord (C#++ on bottom / root omitted). I have calculated fret factors for any scale length. I can also provide a fretboard pattern for any scale length. Let me know if I can help. I'm very interested in your comments, guitarist or not.
