Watch the On The Bebop Stairway online guitar lesson by Fareed Haque from 30 Beginner Jazz Licks You MUST Know
Once again we are connecting "Stairway to Swing" (Lick #16) to the ending of our "A Basic ii-V-I" lick (Lick #21). There are many ways to play the "turn", some players will play all three notes, Ab-Bb-Ab with one pick stroke. This creates a smooth mellow sound. Others will pick the first two notes of the group, thus accenting the Bb note.
Think or sing "Boo-EE-WOO" for the first version and 'Boo-De-Laa" for the second one. Get used to finding different syllables to sing. When the syllables swing, then play like you sing.
