ShiroKuro Ahh, interesting. Remind me, are you playing/uploading music by contemporary composers?

Yes. I have several pieces by contemporary composers uploaded on my channel. My current recital piece is from a contemporary composer (Jay Ungar) and I have other pieces from Angeline Bell and Andrea Dow uploaded as well.

The issue arises when you don't give the attribution. Without it the algo is set to challenge the upload because it might be an attempt to pass the upload off as an "original work" when it is not. When you name the composer in the title this issue is bypassed.

      A piece of music that is less than 100 years old is probably going to get a copyright warning. Some of the original composers / songwriters might still be alive. Even Classical pieces can generate a warning. Sometime ago I posted a Handel piece. It's more than 200 years old but someone posted a more recent soundtrack that sounded similar. I wasn't aware of the more recent recording so there was a copyright warning.

      Soundcloud also has copyright policies based on different criteria. Sometime ago I uploaded a Beethoven Sonatina to Soundcloud (over 100 yrs). The recording was flagged as copyright here but not on YouTube.

      Hmm, that's interesting because I have the title of the piece in the title of the video, and the title and composer in the description, given how searchable everything is and the fact that descriptions are part of what gets searched, you'd think that counts as attribution...

          I didn't write it in kanji. It's a mystery!

            I uploaded my arrangements for cello quartet of the 3 Preludes by Gershwin. Oddly, just one of them tripped the copyright wire, and they are (all) in the public domain:

              This is not my experience, and neither was it pseudonym58's and ShiroKuro's experience. I always have the name of the composer and the title of the piece in the title of the video, but I get quite a lot of copyright claims. Even when I play pieces composed in the 18th or 19th century! So far, every copyright claim I have contested was granted.

              But I think, Player1, you have just been lucky. 🙂

                      The whole copyright thing is a mess. Have known of really good musicians who have quit playing because of getting caught up in it.

                      YouTube, Facebook, and similar sites take musical performances to an unknown and potentially very large audience. Local performances can be a lot more relaxed but there are still things that can happen to drop the ol' fecal remnant in the punch bowl.

                      My recent upload is also marked as copyright but that I'm free to share it. It's the second time I uploaded a piece from this composer and both times it was marked copyright. When I looked a little deeper, it seems that the copyright was for a performer of the work and not actually related to the composer, at least if I was reading it correctly. In this case, the composer died in the 1980s, and so I'm aware that the music score is not in the public domain. Either way, I'm not concerned about it as long as I can still put it out there.

                          Pathbreaker For performance is ok as long as you're not making money off your video.

                          If someone recorded a soundtrack more recently that sounded like a Mozart or Betthoven piece, you still get a warning. Not because you're violating the copyright of a dead composer, but you produced something very similar to the work of a living musician.
