I've been looking at the issue of copyright and BiaB, and it seems clear that I own whatever I create myself and no once can claim copyright on it, including the use of BiaB and the RealTracks. Is that correct?

I don't plan to make any money off this, but I also don't want to be messed with by the YouTube copyright gods. As a musician, part of me agrees that it's legit.

I want to post backing tracks for standards on YouTube created in BiaB. They will be for my own use and posting them on YouTube is just a convenient way to have them available on all my devices. But I may also share links to them on forums for others to use. My assumption is that the chord structures in most standards are not
unique enough to be copyrighted. For example, I believe [ Am D7 G7 Cmaj7 F D E7 Am A7 Dm7 G6 C Am Dm7 G7 C E ] is a chord sequence anyone can use. It happens to a be from a lyrics sheet for Fly Me To the Moon, but it could also be for my own composition. Is that correct?

In order to refer to the "inspiration" for the backing track, I'm considering using a "trick" I've seen in a few places, like the styles embedded in my keyboard, and change the title to distinguish my work from the original. Examples are "A trip to space" for "Fly me to the Moon" and "Simple Samba" for "One Note Samba". I don't think this is cheating. Is that correct? Failing that, I can just call it "Backing Track for Samba". Does that make sense? (In fact, I could have generic titles only I and those I tell would know what they match.)
