Watch the SECTION 8: Keys and Transposition online guitar lesson by Susan Mazer from Hands On Guitar: Beyond Beginner
Now go back and transpose some of your existing tunes. If you’ve been using the capo high up the neck for a song, try playing without the capo, using the new chords. If you’ve been avoiding playing a tune because of that one difficult chord, change the key and find other chords and a key that you prefer. If you've been straining to sing in a key that's just too low, instead of using the capo - transpose. Included in this lesson is a list call “Three and Four Chord Songs.” These are easy tunes that you can practice transposing with.
