As I said in the previous post, trying to figure out which object was which by tossing them wasn’t quite working out. Later that day, I had my assistant assist. He’d flip a coin, and then set one or the other of the two clay shapes in front of me, and I would say which one it was. It was either a small cube, or a small tetrahedron. I made some mistakes at first, but by the time the session was done, the difference between the way one sounded and the other was obvious. The tetrahedron has a sound that almost comes in two parts, as I hear it angle up and back down. I could hear the sharp peak, the roughly 60-degree angle at the top.
I’m told by @seeingwithsound, that a tetrahedron and cube are possible for this exercise, but difficult, and that a cube and sphere would be easier. I might squish the tetrahedron into a sphere and give that a try. It’s easy now when it’s one object at a time, but it might become more confusing when I’m trying to figure out which one is which and they are side by side. Maybe I’ll try a sphere today, and go back to the tetrahedron the next.
After another couple of days, using sphere or tetrahedron with the cube, one object at a time, we’ll try having them next to one another. I’ll have him flip a coin to decide which shape goes on the left and which one on the right. After that, I’ll have to try having them in line, so that one is behind and a bit further away than the other one. Note that I’ll have to stand up for that part—otherwise, the object that’s further away can be blocked from view by the object in the foreground. Sighted readers and those who lost their vision later in life, like me, might find that obvious, but those who have never seen may not know that can happen.
It’s 3:13 in the morning, so it won’t happen until considerably later in the day.
