The I-IV-V Blues Progression
Get inside the most important chord sequence of all as we look at the I-IV-V blues progression
Each note of the major scale can also be played as a chord; the most important of these are the first, fourth and fifth steps. Songs based on these three chords are referred to as a ‘one-four-five’ (aka I-IV-V) progression, regardless of the order they are played in – and this chord sequence can be heard extensively in blues. Learning the I-IV-V chords in as many keys as possible will help you to identify these chords by ear and plot them out on your guitar. Start by jamming around the essential chords in the keys of A and E. We’ve recorded a basic I-IV-V progression: hear it on your TG CD.
