IRC Channel, visual representations & iPhone apps
- Hello everyone!I just got introduced to this group by Dante
firstly, can I point out that there is a really friendly IRC channel #music-theory on irc.freenode.net which would welcome related discussion. (http://webchat.freenode.net/)secondly, may I introduce what I'm doing? I am currently developing iPhone applications to teach musical fluency. my motivation is that I am striving for this fluency myself.so far I have released one app:and my second is going to be a perfect pitch training game, but this has led me into deep and new waters; ie looking at tuning systems notably just intonation, and going backwards even further looking at pure ratios, and the fundamental mathematical nature of music.Already I have a problem. I have got it working by positioning the 12 equal ratio semitone pitch classes at the 12 points of a clock face, and have a needle point in the direction currently being sung. but this is really unsuitable. I have no desire to sing in this tuning system. It sounds all wrong to me. it is not natural for my voice. I need to represent these tones using ratios. Fair enough, I can use just intonation. but now I have a problem. let's say the tone at 12 o'clock is always the keynote, and the remaining 11 get positioned using just intonation. The attached picture gives an idea of this. but what if I want to change key? let's say I modulate from C to D. if I simply use the previous 'D', and recalculate everything around that, that is surely the best option. But this would mean that after some adventurous modulating I might never get back to the original C. and maybe that wouldn't matter?!I can't see any other viable alternative... what are my options?- - - - -on a related note, I started looking at new representations for music last summer, putting up research at www.toneme.org, but my understanding has come a long way since writing those pages. while I still think there is merit in the system I propose, my focus has shifted...I have been trying to come up with a musical system of representation that is as aesthetically pleasing to the eye and logic centre as is to the ears the music it represents.it seems that some compromise had to be reached to represent the infinitude of harmonious sounds that generate from a root pitch using a finite number of physical notes/keys/bells etc.and appears that contemporary musical theory is based not on the underlying mathematics of harmony but upon this representation.this seems analagous to a flatlander observing the shadow of a three-dimensional object, and attempting to model around the shadow.or trying to explain planetary motion from a geocentric standpointso I'm currently trying to get my head around what is at the core.this is my most recent understanding:the third post...so I am looking at possible systems of representation that can illustrate this graphically.I'm guessing this path has been walked before, and I don't really want to waste my remaining life energy reinventing the wheel. can anyone see what I'm trying to get at and give me some pointers?Also, I am very open to new concepts to code up on iPhone/iPad, so any creative input is very much appreciated! if there is something you would like to see out there, I may be able to get it done!Pi
- Hey Gene,
Not sure you read correctly--I wrote that I *do* think it sounds like a decent 7/4; it least it strongly implies it.
