The summary says that the timbre plays an important role in recognizing the notes. I partially agree with this observation, but on the piano, there might be something else than the timbre. Some years ago, I played the "perfect pitch" flash game (http://www.detrave.net/nblume/perfect-pitch/perfect-pitch.swf http://www.detrave.net/nblume/perfect-pitch/perfect-pitch.sw... , still playable if you download the swf and then submit it to https://ruffle.rs/demo/ https://ruffle.rs/demo/ as a local file). Even though I am not a musician, I quickly learned to identify the notes on the medium difficulty level, and often guessed the first note in the session correctly. BUT, I did not only use the pitch to guess the note. In that particular game, the pre-recorded sounds of the piano notes show some non-even volume envelope, or some other way they change their sound over time, unique for each note. So I learned that a "meow-meow-meow" must be an E, and a note that acquires some rattle at the end must be a D. I even reported that as a bug - only to get an email that a piano does sound like that. Of course this knowledge is useless for pure tones, or short-enough notes that are not given a chance to "meow" or to rattle, or, in fact, for anything else than this game.
