YouTube SEO Tags, no unweighted bad tags at all?

Hey folks,
I have a piano blues tutorial channel.
The more general tags have been taken a lot , and so are bad unweighted ( lots of competition despite search volume) like "piano tutorials"
So leave them out completely or does YT still need them as "orientation" what my channel and video is about?
Long-tail terms would otherwise be the majority in my tags. Is that OK?
Thanks very much from Berlin
