chord in scale

[sugizo]

can help harmonization guitarist (rhythm) to assist the melodic guitarist, or melodic guitarist to play arpeggio (broken chord) e.g. when song start to play in major pentatonic scale, the user know what suitable chord to match with the scale
the logic is on the interval that match between the scale and chord e.g.
major pentatonic scale degree = 12356
major chord degree = 135

so when melodic guitarist using major pentatonic scale, the rhythm guitarist can play it with major chord or another chord that match with major pentatonic degree, semitone or interval
