Watch the Transposing Chord Progressions online guitar lesson by Susan Mazer from Hands On Guitar: Beyond Beginner
In every key, there are certain chords that contain only the notes of the key. I’ll teach you what chords are in every key and how to change the song from one key to another. This is called transposing, and with these skills you can raise or lower the key to match your voice. You can also switch from a key that has awkward fingering to a key that has easier chords.
