This study seeks to discover the extent and manner of Debussy's use of the motive in thematic material. A total of 40 melodic examples were analyzed in order to show their relationship to a single motive, a three-note figure having a step-leap relationship. Using eighty-four series of examples, the study shows the melodies analyzed to be 85% motive-derived. The study concludes, therefore, that Images I is a remarkably economical work, using a single three-note motive as a unifying and developmental basis.

The problem is to relate four parameters, thematic development, chord tension, tonality, and rhythm to musical Growth in Karel Husa's Music for Prague 1968. The analytical technique consists of determining a typology and relating that to Growth and is applied in small dimensions to the "Introduction" and in large dimensions to the whole composition. Movement in the composition is goal oriented, and each parameter contributes in different ways, one providing contrast, another continuity, and another variety. Shapes are delineated by cadences characterized by a decrease followed by an increase in Movement. Growth is characterized by Shapes in which Movement starts at a low level, moves to a climax three quarters through, and relaxes for the end of the Shape.
