The musical text of the ap Huw Manuscript is sufficiently large at 86 pages - containing over 10,000 columns of symbols - to enable an assessment to be made of the ways in which the music contained there was organized along formal lines. This paper concentrates on the horizontal or linear dimension of the text, by detailing the ways in which formulae were used to repeat the transform segments of text which were duplicated and transformed between different pieces. The text contains evidence of extensive and heavy systemization of melody, and the paper proposes that this can be very useful in helping us to arrive at an understanding of the music.
