So I'm doing a Rumba solo for jazz band (at least that's how spell check spells it), and I can't come up with anything Rumba'ish. It's not very often that I can't come up with a solo for something, but I always do something too swingish like the rest of the song is. What scales should I work on?

Chords are: C9, G7, F9, Gb7 and the song is: Mary Ann.

god placed the fossils in earth to confuse the humans into thinking that earth is older than it actually is, therefore, making men try and think outside the box....

just kidding, there is no god
