I am fully aphant, but when i played the trombone it absolutely helped me to rehearse purely mentally during the day before a test. There wasn't anything visual about it, though. I just went through the motions mentally, over and over. Outside of that, the whole visualization to practice idea rarely does anything for me. (I still use the term visualization even now that I've discovered it doesn't mean for most others what it did for me!)
