## Description

ChordCalculus is a tool for players of fretted instruments. ChordCalculus will allow the user to choose from a large number of pre-defined fretted instruments in a variety of tunings.   Additionally, the user can define new instruments and/or tunings.    Single or multiple capos can be added.  The user then picks from one of four operating modes using the segmented selectors at the center top of the display:

* (C)hord Calculator:

   Show all fingerings for chords for a given instrument/tuning, filters, capos, and fret span.

* Chord (I)dentifer:

   For a given instrument/tuning and fingering, display all possible names for a chord

* (S)cale Display: 

   For an instrument/tuning, key and scale type, display the scale, and play a two-octave scale 

* (P)rogression Player: 

   Derived from chord mode, display fingerings for a chord progression.  Also plays chords in sequence.

In all cases, the chords can be played as a chord or arpeggio and the scale played back.

As of version 2.0, an instrument tuner is accessed by long touching the tuning button.
