Yesterday I tried playing Kaddish supine while using the black thermoplastic brace that my hand therapist made me. Tonight, I tried again with the thicker, stiffer white brace she also made.
This is the first Kaddish recorded supine but using a hand support—the thinner black one. It helped a lot—the horn was still slipping downward, but it didn’t pull my finger out of position when it did so. This is progress.
