“The history of musical analysis is full of expressions like “a kind of sonata form” , “a sort of rondo” which reveals the desperation of the writer to fit any and every piece into a predetermined form. But in any decent work of art, form is a by-product of material, subject-matter and workmanship, not a process of filling a template, like a dot-to-dot drawing or a do-it-yourself tapistry”.
