Books on composition as insightful as Goeschius?

Question

I've been a magpie for books on composition/orchestration, and it seems to me that the books written by Percy Goeschius are the best, most insightful and well-written that I've come across. Hia *Exercises in Melody Writing* contains heaps of insights about melody that subsume even Schoenberg's writings on the topic, and taught in a progressive way. Another similar golden nugget I've found over the years are translated writings on Partimento Are there any similar such books on composition or orchestration?

Answer 1

Two books which I use a lot in teaching are Leon Dallin's "Twentieth Century Composition"

and Vincent Percichetti's "Twentieth Century Harmony," both of which cover many topics

of melodic writing, chordal resources, and practical application.
