I haven’t really looked for obscure music before, and I’m not having any luck with my usual tv/movie/software sources. It’s “Scherzo No.1 in A Major from III trietti methodichie IlI sche… Jean-Pierre Rampal” (that’s what I could get out of Shazam. Obviously it’s cut off a bit)
Look under the “stats for nerds” for the YouTube video, note the codec used, and websearch from there what quality of audio that codec results in.
Hoping someone else has more than that; my audio interests do not carry me down the particular rabbit hole of defining quality levels. If it sounds good to me, it’s good.
