(Instructional). Chord Bingo is a game-like method for learning how
chords are constructed and how to form them yourself on any chord
instrument guitar, banjo, ukulele, mandolin, keyboard, and others. It's
a novel way of blending theory with application: first you learn a few
easy rules of how chords are made, then you put them to use. That's
where the fun begins. Placing ordinary pocket coins or other small
objects on keyboard or fretboard diagrams, you select the proper tones
for the chord you want, arranging the coins and the tones they represent
in various possible positions. It's that simple. Bingo!
