If I post videos of me practicing certain pieces and/or etudes and offering commentary on where I am with the piece, would that be considered fair use?

  1. It is primarily educational
  2. There is sufficient transformative content; I wouldn’t simply be putting a performance up, and I use the term generously as it is.
  3. It certainly wouldn’t discourage people from buying the real product 🙂 – that is it will likely be noticeably flawed.`

If all else fails,I could always just post excerpts.
