ChordBook provides the ability to look up guitar chords in standard tuning.
It also supplies additional chord processing for 70 non-standard guitar tunings.
ChordBook's purpose is simple: to provide a way to create your own, customized chord listings in the order and with the voicing that you choose.
For starters, the Chord Library for standard tuning has 23 chord types in each key, and it has three to six different voices and fingerings each.
Simply select the key of the chord and its type. You preview it in the Chord Library window, and when you find the correct voicing/fingering, you draw it in the Diagram Editor.
For more information, including on later updates, please read the documentation or visit the home page.
While this version will run on Mac OS 9 with CarbonLib, it's recommended that you get the regular verison unless you are running Mac OS X.
