On the Subject of Guitar Chords
You hum it, I’ll play it.
- The module consists of a guitar fretboard, three level displays and a play button.
- To defuse the module, you must enter the finger positions of the given chords at the capo position.
- Entering a wrong or invalid chord will cause a strike.
- Use the chord chart to determine the position of each chord.
- Press a fret to select it. Press it again to deselect it.
- At each stage, the capo positions are determined by the tables below. Use the first condition that applies.
- The capo position relocates the chord on the fretboard.
- For example, capo 3 will move any fingers on the first fret to the fourth fret. Capo 8 will move any fingers on the third fret to the eleventh fret etc. Any empty strings are unaffected by the capo, and remain empty.
