Proceeding from the basis of simple, chromatically inflected tunes mastered in Book 1, An Introduction to Sight-Singing Book 2 extends the student's technique to encompass the performance of extensive, modulating melodies.

There is further work on minor keys and chromatic notes, and stress is laid on the value of learning to sing by interval as well as by sense of key in order to pitch notes in passages of rapid and frequently changing tonality.

Copiously furnished with examples and exercises, the book concludes with 50 sight-singing studies containing chromaticism and more extreme modulation, representing the most challenging standard of sight-singing technique required in the course of everyday practical musicianship.
