intended for the use of teachers and students of Music Conservatories and Musical Institutes Preliminary remarks and indications for using the method The electric bass first appeared on the international music scene in the early 1950s, and for almost twenty years, it maintained a marginal role in the jazz world, when compared to the double bass. With the arrival on the scene of bassists such as Steve Swallow, Jaco Pastorius, Stanley Clarke, Bob Cranshaw, Anthony Jackson, and several others, the electric bass started becoming more and more relevant in the groups and recordings of Miles Davis, Sonny Rollins, Gary Burton, Herbie Hancock, and a lot of other prominent figures in the jazz community. This method, through several examples and exercises, and a series of technical and expressive elements strictly connected to the electric bass, aims to aid beginning, intermediate or advanced bass players to improve or perfect their knowledge of the jazz language.
