This book explains thoroughly how to write and improvise walking bass line accompaniments on guitar, as in the style of Joe Pass, Tuck Andress, Martin Taylor and others.
It systematically breaks down the elements — choice of notes, chord voicings and rhythms etc and includes examples & pieces which are similar to jazz standards and typical jazz chord sequences.
Together these should give you an overview, ideas and an approach to build on and create your own lines.
You will develop the mobility to play around common chord sequences easily and at speed.
The pdf loads crisply onto any device, Acrobat reader or Apple Books etc.
