Guitar chord
The guitar is very capable and useful for playing chords; but it does have some differences with other instruments. Most guitars only have six strings. This means that for the very largest of chord-voicings it is often necessary to not use one or more tones from the chord. The layout of notes on the fretboard sometimes means that the notes in a chord are not played in tonal order, or make possible a chord that is composed of more than one note of the same pitch. Many chords can be played with the same notes in more than one place on the fretboard.
