This bassline transcription is a request from Dwayne Dixon. He’s a fellow church minister and low note player and sent me a message asking if I’d do a version of Maybe It’ll Rub Off by Tower of Power, so here it is Dwayne!.
The bassline is typically Rocco; punchy, percussive, funky and at times follows the unison riff in the rest of the band. The main A section riff uses a kind of bee bop blues scale (that’s what I shall call it, I don’t know if anyone else does!). The F, E, Eb are like the top of a bee bop scale (in F) with the following C, B, Bb, Ab part of the blues scale (in F) so to my mind that’s a bee bop blues scale or possibly a blues bee bop scale, depending on which way you look at it!
In the hammond organ solo section the bass guitar drops out and bass duties are picked up by Chester Thompson on bass pedals! This section is probably the most difficult to play on the tuba as there’s no where to breathe!
On the whole I found myself playing the bass part on this track with quite a lot of hard tongue attack to get the same sound and style as the bass and bari sax.
