John Valerio - Playing Keyboard Bass Lines (Left-Hand Technique)

This step-by-step approach to learning how to play left-hand bass lines at the keyboard includes examples and exercises covering the chord progressions and styles players will encounter. 

Focus on: walking bass lines, playing in a “two-feel,” waltz time, Latin styles, putting both hands together, and more. 
The exercises for each chapter are recorded on the accompanying audio. 

Audio is accessed online using the unique code inside the book and can be streamed or downloaded.
The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
