Considering that Miles was firmly in a modal music phase at that point, I don't see Jimi's lack of formal training as a hindrance at all. I think he'd be able to hang just fine with Mile's band. Even if Jimi couldn't read changes on a chart, I'm sure he'd have no problem working it out by ear.

In terms of communication, I am thinking of something like the musical equivalent to software design patterns, etc. I.e. imagine two devs are pair coding, one of whom has a CS degree from 2002 and one is skilled but self-taught. While working together, the first starts talking about observer or singleton patterns, which the 2nd has never heard of but has coded something 90% of the way there on intuition. There could be some friction as they establish a common language. (Yes, this is based on experience, with myself more or less on both sides of the exchange at one point or another).
