This is the first in a collection of videos including improvised phrases by jazz guitar player, John Abercrombie. This 1st video's phrase was transcribed from the tune "Autumn Leaves" off Abercrombie's German CD release, "Classic Standards".
About the Jazz Guitarist's Signature Series: Each lesson checks out the improvisational style of a prominent artist within the history of jazz guitar. This is done through a brief transcribed riff, most likely played over a reoccurring harmonic cadence (eg. II-V-I).
