to make matters worse, i experienced a brain injury a few years ago. prior to my injury, playing the E♭ wasn't a problem, because i could transpose "on the fly". after my injury, that capability went away and i had to have all of my parts transposed, so that i could play the B♭ fingerings... much to the chagrin of those who were responsible for supplying me with said parts...
i maintain that the information is still in my brain, but i just lost the "connections" that gave me access to it. that has been affirmed by the fact that i have recently picked up a C tuba, and i'm playing concert-pitch parts with only minor mishaps now and then. i'm fairly confident that, given time, i will be able to return to my E♭ tuba, and even my B♭ tuba, without major confusion.
the brain is amazingly adaptable. i agree with the previous posts: start out with music you already know, so that you will know when you "mash the wrong button" and you'll be fine.
