Ornette Coleman has developed a framework for his ideas called Harmolodics. It is somewhat hard to understand what this constitutes though. It is stated that melody, harmony and rhythm are equally important in this framework, but that is still quite undefined.
Coleman has written an article called "Prime Time for Harmolodics", which I haven't been able to track down. There's also been rumours about a book in the subject since the '70s. Other artists are reported to have used this theory, so it should exist.
There is sheet music included in the "Body Meta" record, which has both a G clef, an F clef and a "harmolodic clef" for each line, but the melody seems to be the usual notes. So there is some specific notation even. (Granted, he could just be messing with us.)
So, any info on what this theory actually implies would be appreciated.
