This project makes and plays different types of chords! Use the left and right arrows to select the root note of the chord. Use the up and down arrows to select the type of chord (major, minor, diminished, major 7th, minor 7th, dominant 7th, suspended, or augmented). Then press space to play the chord. Press R to generate a random chord. Press I to select a new instrument. (In general, voices and winds sound a little more interesting than percussive instruments.)
