ChordCalc is a calculator-like utility for chords. It includes an interactive guitar fretboard to enter and find fingerings, plus 3 other interfaces to build chords and perform common chord operations like adding extensions, transposing to other keys, and harmonizing within scales.

ChordCalc puts chords in perspective by presenting them in the context of the keys and scales. In the Scale Screen you can just drag a chord up and down through keys to transpose it, or drag it across to move through the scale harmonies. The Circle Screen provides an alternative means to transpose and harmonize within the current key and scale, plus a view of the chord on a scrolling piano keyboard.

The Guitar Screen features an intelligent fretboard that can identify and play any chord you throw at it. While some guitar apps may include a pre-defined chord library and set of fingerings, ChordCalc emphasizes complete freedom, allowing you to toggle notes and choose fingerings at any position. An adjustable bracket eases the process by letting you simply choose a range of frets. A fingering for the current chord is automatically generated, then you can modify it from there.

Chord notation provides a convenient shorthand for the notes of a chord, but doesn't necessarily designate their precise harmonic function in every milieu. The notations b6 and #5 both indicate the same note, so they are somewhat interchangeable, but how these notes actually function in a given musical context may differ. In some cases, a note's function might even be totally ambiguous!

The mode names in ChordCalc include major, minor, and diminished designations. These refer to the root triad of each mode (the "point of resolution") taking a cue from sources like "The Complete Guitarist" by Richard Chapman.
