Watch the The Stairway Down online guitar lesson by Sheryl Bailey from 50 Essential Bebop Licks You MUST Know
I bet every guitarist watching this course has at one time played the opening lick to "Stairway to Heaven." If you weren't aware of it, that hook is a very old idea that is often referred to as "the Min7 Line Cliché." The line is this: root down to the major7, down to the minor7, then landing on the 6th. It's a great line to use for II-7 V7 as well, and works great for comping in swing and latin music.
