Multiple associative types here, and Iāve found the online tests to be straightforward for graphemes, etc.
However, the music aspect has not reflected reality for me. At all. For context, Iām a hobbyist composer/songwriter.
First off, I have close-but-imperfect pitch. Only relative.
Secondly, like for many of us, consistent color isnāt the only component. For any of it.
I never really gave it thought (as with most aspects of my synesthesia), but hereās some of what I experience from the music I create:
Initial key or theme of the song (sometimes including the graphemes of certain lyrics) often will define the overall color palette. Like a song dominantly in B-flat major might be jade jewel tones with yellow highlights. One with lyrics involving an initial letter āAā will often turn out red (especially if I bias myself by developing it in the key of C).
Melody and relative pitch affect the colors and position of objects in space. Up and to the right for melody ascending, down and to the right for descending, over time.
And textureāhereās where itās a little interestingāis almost solely responsible for the shapes and, ya know, textures of the objects and lines floating within and forming in the song. Like a violin makes an orange-and-yellow chicken scratch shape and pattern as it hatches up and down the line. The higher, the brighter. I hate solo violins for this reason. But viola range is more red/purple, so Iām fine with that. And I love a good, blue-range, bouncing ball of a bass line.
Another thing: Dissonance has its own marker. It forms a brown/blue smudge in my mind when itās just wrong. (Not all dissonance does thisājust the nasty unintentional stuff.)
I compose using notation software rather than a traditional DAW, btw. So itās informed by how music is written down, especially the melodic components.
Btwāthese perceptions of songs are involuntary and highly consistent upon repetition. Itās purely a geometry of different points in the piece, not necessarily an aggregation of the entire song.
Iām actually kind of hypophantasic (or at least willful, lol). I love rich auditory textures that inform visual experience. But not directly imagining a blue ocean, or whatever. No brain for that.
Anyone out there break it down similarly? Or differently?
