Boomwhackers' Color-coded Chords Posters
Here are Boomwhacker's color-code posters of all major and minor chords. You can also create any chord using the individual circles.
These posters can be used for performance or creation, in large groups or workshops, with any instrument that follows the same color code, for instance, by identifying the bars of a xylophone or some keys on the piano with color stickers.
No time or desire to print, cut, etc.? Build a digital score by taking screenshots of the right chords and project it in the classroom. Ta-da!
You're welcome ;)
