whilst dicking about in the irc with ricemutt, we started talking about ratios for some stupid reason, and we gave me the stupid idea to make this patch-
it started with the blocky sounds of this:
link
which is four notes:
2/4,3/4,4/4,5/4
changing first to
3/4,4/4,5/4,6/4
and then to
3/5,4/5,5/5,6/5
and so on.
he gave me the idea to somehow find a way to do it smoothly, and these sounds were born:

notice how they merge towards a singular pitch each time. nuts
lol here's what #2 looks like in spear

and here's a quick sono that jdg made

now, what might be fun is to let all of us drop markers in those files where we feel that harmony is most pleasing, and compare our results.
And i thought it was really funny how close this gets to most pop music!
And I don't find it odd at all that you and ricemutt would have a discussion about ratios, lol.

I bet alot of us would have very similar results

i'm glad this struck people, too. after hearing it, i felt me and rice had stumbled across something pretty cool, like a kind of voice-leading skeleton key.

I still dont understand what the ratios mean. what are the units of measure? Does that not matter?

the ratios are absolute numbers, like if you were to divide 2ft by 1ft, you'd be able to get rid of the 'ft' and just say it's '2 times as long'.

so how is 2/4 one note? in the first two sequences, they are all 4s in the denominator, why 4? what is the comparison? if the 2,3,4,5 are all being weighed agaisnt 4? Do you see what Im saying? I dont think I know how to ask the right questions.

well I don't know if i'm being two obvious but the ratios are all just relative to an original frequency of whatever choosing. so the units of measure are going to be in hz, and but the ratios don't really interact with that, they just are relationships to the specified fundamental. so if roid's fundamental was 700 hz then 2/4 would just mean "frequency of 350" and so on.
the fact that astroid chose all fours to be in the denominators is pretty much just arbitrary--roid just liked the sound of a certain kind of manipulation on the ratios, so he took it and ran, and then devised a simple arithmetic sequenced and followed it to its logical conclusion. None of us really know exactly what's happening to the frequencies, though we could figure it out if we were a little smarter.

god my grammar and spelling were horrible there, I was kind of distracted...
yeah ratios are just another way of creating pitches. Sometimes I think using ratios as pitches is just as arbitrary as any of the other ways we define pitch--but just like the idea of a scale gives us a convenient way to mentally organize the pitch continuum ratios also give us a way we can think about pitches. but most of us just aren't used to thinking of pitches with numbers like that--and it's a lot more rich, than say, just having a list with 12 elements in it, like a tempered scale.

So Im thinking about it in terms of one notes relationship to another... like waves interacting with each other (example): in any one period of time, one notes frequency is such that there are 5 cycles in that time, and the other note has 4 cycles = a 5/4 relationship.
So if these ratios are one note, what is the relationship? a ratio is implicitly a comparison of two values, right?

Ok I was writing that as you were writing yours, ricey... I missed the arbitray fundamental pitch part.
