Ultimate Chordbook


Jack Herrington is a professional programmer living and working in the San Francisco Bay Area. He has a part time interest in guitars and Music Theory and a full time interest in making unique applications that are fun, easy to use and helpful.

Jack wrote both the Fret Navigator application and the Ultimate Chord Book. Fret Navigator is a fully featured Macintosh application written in Think C+- using the Think Class Libraries. Fret Navigator layered the chord and scale finding technology on top of a full featured tabulature editor.

The Ultimate Chord Book started as an experiment in Python and JavaScript. The first version was completed in less than a week with Python.
