Johan - that's basically how the code is already implemented. I'm mainly asking in this case if I should just handle lowercase chord letters the same way I handle uppercase. I can just convert the letters to uppercase before looking for a valid chord letter and the code should allow those letters in the same way (although when transposing I guess I would have to modify the code to leave the letter as a lowercase letter instead of converting to an uppercase letter). I was just hoping to get some guidance on whether that is the right thing to do or if it could potentially cause unusual behavior for users that might have put non-chord words inside brackets in lowercase letters to avoid having them handled as actual chords. Your last sentence makes me think you believe I should just allow the lowercase letters and handle them like any other chord definition. If so, I'll move forward with making the necessary changes.

Thanks,
Mike
