摘要

The inventors found that after the appropriate Feiten Rule of Compensation was applied, accurate intonation could then be achieved by slight adjustment called tempering. Accurate intonation is hereby defined as intonation which is pleasing regardless of where a player's fingers are on the fret board. The process of tempering is normally restricted to adjusting pianos, and entails adjusting strings by ear until all notes sound pleasing to the ear, in any key, anywhere on the keyboard. As past attempts to temper the guitar have been haphazard, unsystematic, and thus ultimately unsucessful (resulting in poor intonation), the method of using a set of constant tempering offsets is a revolutionary concept in guitar intonation. The tempering process incorporated by the inventors does not consist of random adjustment. Rather, the inventors derived a combination of constant, open-string (unfretted) tuning offsets and intonation offsets (at the 12th fret). The inventors have identified multiple embodiments of constants which serve to intonate any stringed fretted instrument, hereby titled Feiten Temper Tuning Tables.
