The study of Harmony generally consists of writing notes, mathematically calculated from a figured bass, without hearing their sound or understanding their use and bearing upon playing or singing. A musician must be able to read and hear written music as readily as he reads his mother tongue. The purpose of this book is to show the pupil how to study and apply Har mony, to develop the ability to hear what is written and to furnish exercises for study. Each Lesson is divided into three Sections: Section A contains the exercises for written work, applying Harmony to Melodic Construction and Harmoniza tion, and the study of Form; Section B, the exercises for Harmonic, Interval and Melodic Dictation; Section C, the exercises in Singing Intervals, Rhythms, Chords and sight-reading.
