Is anyone able to explain the concept of a harmony lead? I am not strong in theory and do a lot by ear and feel but two musicians in our new band are well schooled in music and asked if I could come up with a harmony for one of the lead lines in a song. It is only 8 notes and it descends down the neck....so it is more a melody under a chord progression as a bridge section of the song. What exactly is it technically to play the harmony? I want to write a harmony with the keyboardist and other guitarist. Thanks!
