“Comprehensive Aural Skills lives up to its name; together, the book and the companion website contain all the materials needed for an aural-skills curriculum. … Comprehensive Aural Skills effectively combines singing and dictation activities in rhythm, melody, and harmony into a single book, and the high quality of the recordings makes Merritt and Castro’s print-plus-digital package far more attractive than many automated dictation programs with low-quality MIDI. The inclusion of answer keys at the back of the book also makes this a viable resource for supplemental practice or even independent study … nearly everything else needed for a four-semester curriculum is provided.” — Samantha M. Inman, Music Theory Online, vol. 23, no. 3
