Steve Prosser's "Intervallic Ear Training for Musicians" is the product of 35 years studying and teaching interval awareness in music. The text provides a step-by-step method for assimilation of, as well as graded exercises for, each interval.
Each Chapter concludes with Mastery Exercises and Etudes. After adequate study of the text, the student will be able to hear, recognize, read, and write music through the use of musical intervals.
This skill is particularly helpful in dealing with music that is extremely chromatic, tonally ambiguous or rapidly modulating.
