Worked first time.
That's unusual for me.
The ADDAC radio is not providing a very good signal: that needs fixing.
And the Thonk Radio Music kit arrived today.
[26 Aug] And the Erthenvar Fibonacci today. It is beautifully built.
"The reason this idea came to mind was a recent piece in The Times referring to a lecture by Marcus du Sautoy at the Royal Society available here entitled The secret mathematicians, it concerned the use of maths in art and starts with a piece by Messiaen, Quartet for the End of Time. It uses rhythms of 17 and 29 beats - as these are prime numbers, a sequence would not repeat (at least until you get to 17*29).
I think La Monte Young used primes too.
The lecture also refers to the Fibonacci series which I think is mentioned in a later post but I haven't got there yet.
Anyway, as I play with long automated noises, I thought prime-based rhythms would be fun.
A prime number is only divisible by one and itself (2, 3, 5, 7, 11, 13, 17 etc).
