I decided to write this book since, almost always, in the ones I bought over the years, let's say on the same "style," I never found the explanation of what was being offered. I could limit myself, therefore, to learning bass phrases, fills, grooves, without really understanding the meaning. Why were certain notes being played? Why were certain rhythmic elements working beautifully? On what chords were the bass lines "thought"? What scales or arpeggios, or substitutions, were being used and why? These, each time, were just a few of the many questions I asked myself after "parroting" the various examples offered. Another thing, in my opinion instead fundamental, in all the books I bought, there were audio examples, but no backing tracks without bass to be able to play and study in the best way. As with almost all my other instructional books then I thought, "Why not write one, exactly as I wished the ones I purchased years ago had been?" The title is a bit generic, because in reality not only Funk is covered, but also many similar styles of music from various different eras, and, in addition, many bass lines take inspiration from the greatest bass players in the history of these musical genres. Some examples: Francis "Rocco" Prestia, Louis Johnson, Jerry Jemmot, Bernard Edwards, Paul Jackson, Chuck Rainey, Flea, James Jamerson, Pino Palladino, Jaco Pastorius, Alain Caron and many others! Each proposed groove is then analyzed rhythmically and harmonically, and, indeed, I have tried to make it clear why I use certain scales, arpeggios, substitutions, "out" notes and "in" notes, etc., etc.
