After a search on Sheet Music Plus, it seems BBb literature is lacking in general. Go figure, it's such a rare instrument. I own one but find it inconvenient that it gets out of adjustment very easily. And I lack the skills to make the appropriate adjustments. I don't want to fiddle around with it because I might make it worse. The key rods are very long and can bend easily if not handled properly. Whenever I press the low Eb key with my right pinkie, I have found that the low F key pad does not seal perfectly. It has been like this for a while. I brought the instrument to my local repair technician years ago, but even he did not resolve the issue. So I just kind of gave up on the instrument. I play it once in a rare while, despite the low F key pad not sealing perfectly. I kind of wish I had purchased a Leblanc Model 350 instead of the Model 340 years ago when I bought it. Perhaps the EEb would not have been such a potentially high-maintenance instrument. I own a Selmer Bundy EEb; my parents bought it for me when I was in High School. And I never had adjustment issues with this clarinet. The only problem I encountered was the fact that the case for it was too heavy for the case handle.
