A systematic instructional manual that presents the principles and practice of species counterpoint alongside freer, more compositional applications, guiding students through the rules for melodic motion, consonance and dissonance treatment, voice‑leading, and the progression from strict two‑voice exercises to multi‑voice, florid, and fugal writing. It explains the rationale behind prohibitions and allowances in intervallic motion, offers exercises and illustrative examples, and shows how to apply strict contrapuntal techniques to real musical forms so that learners can develop secure part‑writing, contrapuntal invention, and analytical understanding of tonal counterpoint.
