DESCRIPTION:
Chordal Jam - A Closer Walk (Blues Version) for 'harmonica lung therapy' using the 'medical harmonica' invented by J. P. Schaman, M.D. uses visual "box" cues to help with the chord changes. New with this video is the "preview" smaller sized box cue showing up one barr (measure) before the actual chord change (the small box cue becomes full size when the chord actually changes). These cues are of three types: positional, colour, and hole layout on the harmonica.

Positional cues:
1) F chord is left upper quadrant requiring blowing on the left side of the harmonica
2) C chord is left lower quadrant requiring drawing on the left side of the harmonica
3) G chord is right upper quadrant requiring blowing on the right side of the harmonica
3) D chord is right lower quadrant requiring drawing on the right side of the harmonica

Colour cues:
1) F chord is red
2) C chord is blue
3) G chord is yellow
3) D chord is green

Hole Layout:
1) The holes to be played are coloured in the designated colour
2) Blow or draw is designated by "b" or 'd" respectively
