The Tenori-On and maths

  1. I saw Bill Bailey playing one of these a few weeks ago and found this online version

    The prime numbers make a rather nice tune, as do various graphs.
    Is there anyone out there who could program one with different sized grids? I'm not clever enough to do so but I thought that it would be a nice distraction to investigate different number patterns with different bases.

    Thanks for this - I just spent 4 hours playing with it! fiddling around with primes, squares, times tables etc. This sequence is the 7*table 2064,16512,1032,8256,66052,4128,33026,2064,16512,1032,8256,66052,4128,33026,2064,16512 Just copy & paste into the flash utility.
    Not sure I really understand the different-sized grid question though. The notes available in the grid are the notes of the D Major Pentatonic scale (I think). Wouldn't a 10x10 grid (say) require some strange scale. Dunno i'm scratching my head now.[​IMG]
     
  3. I guess that it could be done by splitting the octaves into different ratios. I'm not sure if it would work musically or not though.
