Watch the Let's Rock: Rhythm online guitar lesson by Joe Deloro from Blues Rock Road Trip
This lesson features two of the most powerful elements in early guitar-based Blues-Rock: swinging eighth note (triplet based) background riffs and "rhythmic" solos. That is, Boogie-Woogie style riffs are used for the rhythm parts, while the leads are created primarily from strumming, arpeggiating, and/or tremeloing two or three strings from the chord of the moment, instead drawing from licks and/or scales. Typically, both riffs and leads are derived from Dominant Seventh chords and 12 bar blues related chord progressions.
One of the best examples of this approach is found in Elvis Presley's, Jailhouse Rock (1957). Although recorded in Hollywood, it features the classic Memphis sound of Scotty Moore. Jailhouse Rock's Chorus solo is based on the last 8 bars of a typical 12 bar blues progression and is the inspiration for this lesson. Also, the tempo is brisk, and whether you call it a shuffle or swing, it needs to bounce, so don't play it straight (even eighths). For other examples of this style listen to more of Scotty's work, as well as Carl Perkin's and the classic solos of Chuck Berry.
