@saved I generally would not think of this piece as yellow. My Audio-Visual Synesthesia is mostly timbral, though it is also affected a little bit by register and pitch classes/keys. So timbrally strings tend to be warm browns, and the harp tends to be glistening white but more dot-like in shape, rather than the ribbon of sound of the strings. In terms of key, it tends to be focusing on F and D I beleive (I do not actually have perfect pitch). F tends to give a warmish orange color where D tends to be brown, but oftentimes a sparkly brown, though the section in D iis minor and I think the sparklyness comes from the major chord, which the melody tends to end on. Its really quite complex and hard to explain because there is a lot going on when I see music.
Yellow tends to be associated with Brass Instruments, especially cylindrical instruments like the Trumpet and Trombone, (Conical Instruments like the Horn, Euphonium, and Tuba tend to be a bit more colorful and expressive). That being said, a lot of trumpet/bugle calls tend to be yellow. Also keys centering around E tend to be yellow. Oddly, due to Orchestration and other factors Dvorak's 9th Symphony in E Minor is much darker and warmer in color scheme with a lot of oranges and browns. Tchaikovsky's 5th is pretty Yellow, especially the ending of the last movement. There is also quite a bit of yellow in pieces like Also Sprach Zarathustra and Aaron's Copland's Fanfare for the Common Man, however there is a lot of open spacing in the chords of those works
which gives it a very powerful, wide and big, but almost empty sort of feel.
I think I will post the finale to Tchaikovsky's 5th, at the end of the 4th movement.
While it isn't Perfect this yellow gets pretty close to the primary color scheme at the beggining and end of the movement (though the trumpets are a little bit buzzing in this verson making it fuzzier than most versions I have heard).
That's a lot to take in. You are clearly far more technically knowledgeable about music than I will ever be so some of it is sadly beyond my understanding. 🙂
I am quite surprised by the complexity and detail in what you see. I'm also surprised, although I don't understand why, that you see any yellow at all in Also Spoke Zarathustra and Fanfare For The Common Man. As regards your Tchaikovsky example - I feel (not see, of course) mid blue with splashes of yellow.
Then I remember that you have a hard-wired response to the sounds, not simply a "feel" for them.
There are many more questions I would like to ask, but I am wary of hijacking this thread.
I find all of this fascinating. Thanks so much for taking the time to reply.
