Hello

Heya,

I'm new to this forum, so I'd like to introduce myself. My real name is Jacob Collstrup and I live in Denmark. I registered on these forums, because I like maths and I'm hoping to learn more, much more.

So a good hello to you all! =oD

Best regards,

Jacob Collstrup

Re: Hello

Welcome! I saw your post about music and math, good stuff. It's a topic that often comes up at the OEIS, albeit not one we're quite figured out, aside from adding the option to 'play' our sequences. Some have a surreal sort of beauty to them, but most just don't work well in that format.

Re: Hello

Well, the trick I used to make the Fibonacci sequence "ear-worthy" is to set it mod 5 and play it on a pentatonic scale. Note sequences almost can't sound bad if you keep things pentatonic, which is why lots of popular songs use them, they are used in early music education and novice improv artists (like me!) try to pick one appropriate for a given piece and stay on it with just the occasional "passing note" off the scale, after which you hop right back on. When I compose, I like to use more notes, including lots of half tones. But when you gotta "compose on your feet", you can end up with a lot of nasty clangers if you get too adventurous too soon. Same with formula driven music. Give it too many "landing spots" and you'll end up with musical phrases from hell or, worse, something that sounds like John Cage wrote it. Popular pentatonic scales are Do-Re-Mi-So-La and Do-Re-Fa-So-La, ie skip either Fa or Mi and Ti is RIGHT OUT. You can of course set these to any key.

Re: Hello

Good idea, in general, but since the Fibonacci numbers are periodic mod 5, the tune might get a bit old. (Of course it's periodic to any modulus!)

Which is why I made it a simple bagpipe call (using the bagpipe mode on my keyboard and simulating a drone by holding down the Gs one and two octaves below the G-based pentatonic scale I was using).
