The two pentatonic scales we use in guitar solos are the major pentatonic and the minor pentatonic scale. The major pentatonic scale has five notes – the root note, the second note, the third, fifth and sixth. The minor pentatonic scale contains the root, flattened third, fourth, fifth and flattened seventh. In the key of C the major pentatonic scale is C D E G A and the minor pentatonic scale is C Eb F G Bb The minor pentatonic scale is commonly used to solo over guitar chords. Mastering the knack of soloing with the minor pentatonic scale will add unimagined excitement to your hitherto dreary guitar solos. So how do we best exploit this handy guitar player’s tool? We are going to learn to how to play solos guitar chords over major, minor and dominant chords. Let’s take a common chord progression using the root, fourth and fifth notes of the scale. If we are playing a song in the key of C major, the I, IV and V chords are C, F and G major. For every major chord there is a relative minor chord. You can best find the relative minor of a major chord on your guitar by finding the note that is three frets below the major chord’s root note. Let’s say we have a C major chord, the root note will be C. If you take the C note on the fifth string of the guitar which is at the third fret, three notes below that gives us the open fifth string which is the note A. So if you ask what the relative minor of C major is, the answer is A minor.
