Watch the Jumping the Moon online guitar lesson by Freekbass from 50 Freekbass Licks You MUST Know
Both good as a line to use in a song, and as a good warm-up exercise. This lick is based aorund the key of Eb minor. The idea is to keep your index finger on the root note (Eb on the 6th fret of the A string) while moving back and forth to different notes in the minor scale.
Unlike the last lick, Easy Bounce, where the idea was to keep all of the notes short, with this one, you will want the notes to be more legato which will create more of a haunting feel. Also, be aware of the string jumps with the Eb on the D string, and the Db on the G string, using the index for all of those too by a nice even rocking of the finger back and forth.
