Watch the Half Step Hits online guitar lesson by David Hamburger from 30 Blues Intros, Turnarounds, & Endings You MUST Know
Notice the melody formed by the top notes of the voicings in bars 1 and 2. Like some of our other licks, this one is aiming for the sound of horn hits, in this case, the kind you'd hear on a jump blues record. From this intro, you'd go right into the top of the blues form. Alternatively, you could replace that F7#9 in bar 4 with a big fat Bb7 or Bb7b13 and roll right into bar 5 of the form (Righteous hepcat swing soloing not obligatory, but highly recommended).
