Watch the Step 1: Identify the Prevailing Chord online guitar lesson by Frank Vignola from 1-2-3 Jazz Chord Melody

In step 1, we're going to look at the sheet music and identify the prevailing chords. For example, in Take Me Out to the Ballgame, in the first two measures the prevailing chord is a Cmaj, in the 3rd and 4th measures the prevailing chord is a Gdom7. In measures 5 and 6, the prevailing chord is a Cmaj once again, and in 7 and 8, it's Gdom7.
