I've recently been attempting to teach myself how to compose serially. I've found sufficient material on the internet to understand tone rows with x number of pitch classes and how to build matrices for permutations. I cannot, however, find enough material to help me understand how to apply contour to a tone row (is this only applied to integral serialism?). I've ran across short number sequences for contour to which one may apply permutations (ie. A B A') but I still do not understand the number sequences, and if I did I wouldn't understand how to use multiple parameters.

Could somebody explain how to go about writing integral serialism? Or direct me to the right resources?

thanks
