Abstract
Abstract A fingerboard construction for a stringed instrument such as a guitar employs a fret placement resulting in a sound characterized by perfect pitch octaves, fifths and fourths. According to the first fret placement, which begins by placing the twelfth fret, high E, exactly at half the distance between the nut and bridge of the fingerboard, perfect fourths can be found at exactly half the distance between their respective fifths.

Claim 1
Independent Claim
193 words
A fingerboard construction for a stringed instrument such as a guitar, said guitar having a nut, a bridge, a neck connecting said nut and said bridge, and a fingerboard mounted on said neck and extending from said nut to said bridge, said fingerboard comprising a plurality of frets sequentially mounted transversely on said fingerboard such that 1) twelve frets comprising a first fret through a twelfth fret correspond to an octave of half-tones and said twelfth fret is mounted equidistant between an inside face of said nut and an inside face of said bridge as measured along a symmetric center line on said fingerboard extending from the inside face of said nut to the inside face of said bridge, 2) each fret corresponding to an interval of a fourth degree is mounted equidistant between frets corresponding to respective intervals of fifth degrees as measured along said symmetric center line, and 3) each of said first fret through said twelfth fret corresponding to a given half-tone is mounted at a distance from said nut equal to twice the distance from said twelfth fret to a fret corresponding to the given half-tone up one octave.

A fingerboard construction for a stringed instrument such as a guitar, said guitar having a nut, a bridge, a neck connecting said nut and said bridge, and a fingerboard mounted on said neck and extending from said nut to said bridge, said fingerboard comprising a plurality of frets sequentially mounted transversely on said fingerboard such that 1) twelve frets comprising a first fret through a twelfth fret correspond to an octave of half-tones and said twelfth fret is mounted equidistant between an inside face of said nut and an inside face of said bridge as measured along a symmetric center line on said fingerboard extending from the inside face of said nut to the inside face of said bridge, 2) each fret corresponding to an interval of a fourth degree is mounted equidistant between frets corresponding to respective intervals of fifth degrees as measured along said symmetric center line, and 3) each of said first fret through said twelfth fret corresponding to a given half-tone is mounted at a distance from said nut equal to twice the distance from said twelfth fret to a fret corresponding to the given half-tone up one octave.
Claim 3
Independent Claim
193 words
A method for making a fingerboard for a stringed instrument such as a guitar having a nut, a bridge, a neck connecting said nut and said bridge, and a fingerboard mounted on said neck and extending from said nut to said bridge, comprising mounting a plurality of frets sequentially and transversely on said fingerboard such that 1) twelve frets comprising a first fret through a twelfth fret correspond to an octave of half-tones and said twelfth fret is mounted equidistant between an inside face of said nut and an inside face of said bridge as measured along a symmetric center line on said fingerboard extending from the inside face of said nut to the inside face of said bridge, 2) each fret corresponding to an interval of a fourth degree is mounted equidistant between frets corresponding to respective intervals of fifth degrees as measured along said symmetric center line, and 3) each of said first fret through said twelfth fret corresponding to a given half-tone is mounted at a distance from said nut equal to twice the distance from said twelfth fret to a fret corresponding to the given halftone up one octave.
