Textbook choices are frequently part of those deliberations, as instructors strive to deliver the material efficiently, accurately, and musically. Even if one's department is not in the throes of reconsidering its approach to aural-skills instruction, current market forces might encourage such an exercise, for the year 2007 produced a wealth of sight-singing and aural-skills textbooks. Of the four texts under review here, two are new to the market, and two are revised editions of classic texts.
