Ultimate Chordbook


What makes The Ultimate Chord Book unique is the algorithmic approach used to find the chords and scales. Instead of using a database of known chord fingerings, the Ultimate Chord Book generates chords on the fly by searching for them on a virtual fretboard. This means that you can find any chord spelling you want, on any instrument tuned with any tuning.

Because of this algorithmic approach we are free to experience with new tunings, new chords and new scales without worrying about the complexities of building chord and scale fingerings.

The Ultimate Chord book is based on the algorithms first used in the Macintosh application Fret Navigator. Fret Navigator is available on this site.
