The purpose of this study is to acquaint the reader with certain scales, not merely as they are used to provide the theoretical "building stones" of all music, but as they have been used as actual scale passages in the piano music of two twentieth century composers. This is a study of the use of various scales in the piano music of Debussy and Ravel. A list of the piano music of these composers which was available for the present investigation is given in the Bibliography. A careful analysis of the music has been necessary in order to determine: First, the types of scales the composer uses; second, the interpretation of the scale in its context; third, the ways in which some scale passages are employed to help project musical thought in the composition; and fourth, the frequency of occurrence of types of scale passages.
