New Charango Chord Patterns for Android devices. [for Android 4.0.3, API 15, or newer]

12 keys, 18 chord patterns per key, 3 fretboard ranges, for a total of 648 chord patterns.

This application does not use a database; it computes all chord patterns based on interval theory.

Includes the following chord patterns in all 12 keys: major, minor, 7, m7, maj7, 6, m6, 6/9, 9, m9, maj9, augmented, diminished, diminished 7th, 7+5, 7-5, sus4, 7sus4.

Chord patterns go further than chords: they display intervals, so you can deduce all of the chord positions along the fretboard.

Straight-forward Charango chord pattern selections for all sorts of players (beginners, amateurs, and professionals).
Easy-to-use interface, with all options on one screen. No hidden options, no nasty ads, what you see is what you get (WYSIWYG).

Displays chord notes and intervals.

The application displays in landscape mode, and feels comfortable in 800x480 pixels (4.3 in, or bigger) screens.

NOTE: The application does not produce any sounds, and does not support alternative Charango tunings.
