Now that you know the basics of reading accidentals, it's time to play the blues!

The Blues

During the late nineteenth century, African Americans living in the rural southern United States invented a unique musical style called the blues. The blues is also notable as an influence or foundation for jazz, R&B and rock styles.

Blues Form

The blues revolve around a pattern called the blues form: a repeating 12-measure chord progression. This structure is part and parcel of the blues, although the form eventually became ubiquitous in jazz, rhythm and blues and rock and roll.

The blues form is apparent when viewed as a diagram. Blues musicians vary and embellish this pattern, but the basic 12-bar pattern remains intact. Here's the blues form in the key of G major:

In the above graphic, rows are read from left to right. Boxes represent measures and letters stand for chords. This pattern is the road map for all blues pieces, including today's assignment.

Melody

The challenge of the melody is mostly about getting used to the new symbols and the sound of chromatic notes (notes out of the key). If you're reading TAB, there are no new symbols to read.

Begin by listening to the Frary Guitar Duo's tiny office performance of the Accidental Blues. As usual, Peter is free stylin' the chords, but they're the same chords as written, just jazzed up a little. We'll work on an easier chord pattern further down this page.

Practice the melody until smooth. Play along with the audio track or video to enhance your rhythmic accuracy.

Once the melody of the Accidental Blues is smooth, work on the chords.

Chords

The chords of the Accidental Blues are few and mechanically simple. Changing chords in the right place is the main challenge. For example, the first chord, G, is played for four measures—sixteen beats—before changing to C. How do you keep track of when to change? Simply count 1-2-3-4 four times and change to C.

The down 2X strum—strum on beats 1 and 3—is recommend for this piece.

The down 2X strum is a good choice because it leaves space for the melody to shine and brings out the metrical accents. The flat-four strum also works if you keep it soft enough to avoid drowning out the melody.
