Watch the Harmony Lead: 13 online guitar lesson by Robbie Calvo from SoloCraft
This is the harmony a 5th above the melody. You are listening to the 3rd and the melody underneath me playing the 5th. So, we now have a three part harmony. Think about this - the 3rd is a 3rd above the melody and the 5th is a 3rd above the 3rd. Thought that would send you into a tailspin. Don't worry, be happy!
