Watch the Flat Tire Groove online guitar lesson by Jasper Mortier from 50 Blues Bass Licks You Must Know
Although Flat Tire groove is relaxed, it's still cool to try to work with the dynamics. What really can change the pace is shifting your part from a standard I-III-V pattern to for example a lowering double note pattern e.g. VIII-VIII-VIIb-VIIb etc. Note that in the original version from1955 B.B’s drummer switches from a so called flat tire to a straight shuffle in the guitar solo. Feel how this interacts with your playing. B.B. King almost used it as a trademark to speed up in a slow blues for instance. This strongly emphasizes the excitement. For a while he even played with 2 drummers: one was pushing and providing this urgent feel while the other one was keeping the tempo straight. But in his particular song the beat stays steady the whole way through! Another great - bit faster - example of this groove is The Hustle by T-bone Walker and you could also listen to James Harman's Time will Tell.
