This programmed version of a classic introduction to the basic essentials of music shows the relationship between theory and "real" music. Presenting information in a step-by-step programmed format, this book covers the most elementary aspects of music --including music notation, time, scales, keys, intervals and basic concepts of chords. The information is introduced in small increments, followed by questions with answers for reinforcement. This edition makes liberal use of examples from music of recognized composers and from familiar folk-song sources to illustrate technical information. A book designed specifically for beginners in music theory, or those with varying backgrounds in music.
