If you know a song in standard tuning you can quickly and easily change the key of it by simply applying the capo, using it as your new nut, and playing the same chord shapes you already know. Another excellent way to use the capo is during recording, where rather than having two guitars play the same position, you can use a capo to change the voicing of the chords.
