In recent years, with advances in electronic keyboard technology and decreases in music performance budgets, the keyboardist has been called upon increasingly to play multiple roles. Among these roles is that of a bass player. This book provides a step-by-step approach to learning how to play left hand bass lines at the keyboard. It offers examples and exercises covering the chord progressions and styles that the player will encounter in the real world. Players of all levels will benefit from the focus on walking bass lines, playing in a two feel, waltz time, Latin styles, and putting both hands together.
