Summary: This free guitar lesson answers the question "What is the key of a song?" You learn about tonic pitches, relative major and minor, modes and key signatures. You see that the key of a song doesn't always reflect the true parent major scale and it's up to you to go beyond the basic details and sort out the other components at play. Several popular songs are used as examples. Taught by Desi Serna author of Fretboard Theory Volume II.
