(Guitar). Know only 20 guitar solo licks? How about 50? 100? 200? If that's all, then you need this book, designed to help you improvise bluegrass style guitar solos. These 400 licks are played over standard chord progressions; the use of licks sometimes will take precedent over stating the melody. The progressions used are based primarily on common vocal numbers. Some of the licks included are: two-measure G & D licks, blue note licks, pentatonic scales, licks with slurs, boogie licks, moveable licks, embellishing a fiddle tune, practice loops of "Salt Creek" and "Billy in the Lowground" and many more.
