First we prove that chunk sizes can't differ by 2 or more. | First we prove that chunk sizes can't differ by 2 or more. | ||
By | say you have some intvl class (k steps) with 3 variants in X's and Q's: | ||
* S1 = a1X + b1Q, represented by the word s1 in the MV3 scale | |||
* S2 = a2X + b2Q, word s2 | |||
* S3 + a3X + b3Q, word s3 | |||
(si to be chosen later) | |||
Say that the mos formed by the Ys and Zs is rY sZ, wolog r > s. | |||
The # of chunks in rY sZ is s. The min chunk size is floor(r/s). | |||
The idea is to keep extending si to the right until the chunk size in the MOS guarantees an extra variety. | |||
By manually eliminating finitely many cases, we can assume that the scale is at least 5 notes and we have at least three Qs. | |||
have some length (say that of max chunk) word with no q's,one q and 2 q's. | have some length (say that of max chunk) word with no q's,one q and 2 q's. |
