Watch the Blues in F: online guitar lesson by Andy Aledort from Slow Blues Power
This next example of slow blues soloing is based on an eight-bar form, as opposed to the more prevalent 12-bar form utilized in the previous example. This chord progression is interesting also because it strays from the tried-and-true I-IV-V (one-four-five), three-chord type of progression that is the most commonly used blues progression. Here, two bars on the I chord, F7, are followed by one bar on the IV chord, Bb7, and then one bar on the “flat-five-diminished” chord, which in this case is Bdim7. Bar five features a I-VI (one-six) chordal movement, from F7 to D7, and bar 7 features a II-V (two-five) chordal movement, from G7 to C7. The progression then wraps up in the standard I-IV-I-V (one-four-one-V) chord movement of F7-Bb7-F7-C7. You’ll hear similar eight-bar chord progressions on songs like “Someday After a While” by Freddie King, “It Hurts Me Too” by Elmore James and “Sitting on Top of the World” by Howlin’ Wolf.
