In previous posts I’ve discussed improvisation.
“Licks” are certain note patterns which can be played over chord changes. Learning certain licks and patterns is important so that you can recreate cool sounds on the bandstand which you worked on in the practice room.
This site (http://bopland.org/) is great for learning and practicing licks which you can then put into your solos.
Have fun, it’s a great database of some of the coolest licks around!
