I can "hear" a song at will. I can "hear" it well enough to think about the instrumentation, etc.
I can't "visualize" a pretzel. I go into an analytical mode and a gut-level physical mode, thinking about pretzels and their different aspects with momentary "pops" of "visualizing", but they aren't stable and continuous, the way I can imagine a song or any sound.
Oddly, I started life as a visual artist before computers. I've met both total aphantasia-suffering artists and artists who can visually project onto a blank page and trace what they are seeing. People are somewhere on this spectrum.
How do you solve geometry problems. For lots of them I visualize / rotate things im my head.
Have you ever seen a pretzel (or anything) in a dream?
can you draw a pretzel though? Like, if I handed you a pad and pen and said just draw one from memory?
Greetings fellow music-hearer.
My s/o will sometimes get irritated when I'm silent for a while on a car trip or at dinner. I'm not trying to be rude, I just get caught up in a song, just as if it were playing in the room. Vocals, drums, instrumentation and effects, the whole thing is just right there.
I can visualize things, usually scenes and favorite places, but they are more abstract than the music is.
