When Alberto Ginastera's oeuvre is viewed as a whole, an essential continuity between compositional ideas often appears in different works. This is especially apparent in the three piano sonatas, where each sonata represents an evolution and a condensation of ideas occurring in the previous one. The evolution of ideas throughout the three sonatas takes place through two primary processes. The first is a shift in cultural focus from reliance on Ibero-American material in the first sonata (1952) to Amerindian in the second (1981), to a synthesis of the two cultural elements in the third (1982). The second means of evolution from sonata to sonata is through a process of symmetrization. Along with constructions using symmetrical scales, material in each of the three sonatas is subjected to various symmetrical procedures which correspond musically to basic geometric symmetry types or operations (bilateral, rotational, and translatory, for instance). The decreasing number of movements evidences a negative dilatation of material, moving from four movements in the first sonata to three in the second, to one in the third. In each case, corresponding material from the previous sonata is integrated into the following sonata. Both independently and as a group the three piano sonatas exhibit "invariance under a transformation."

The purpose of this study was to develop and apply an experimental grading system to sonatas written by American-born composers from 1950 to 1975. Although several authors have addressed the problem of grading or classifying piano music, there are generally no precise criteria provided to substantiate the validity of their systems. The present author discovered some significant and innovative yet generally neglected piano sonatas.The grading system in this research was based on the physiological factors effecting the pianist's development. These factors include: 1) Equality of Fingers (finger independence and mobility); 2) Passage of the Thumb (scales and arpeggios); 3) Double-Note and Polyphonic Playing; 4) Extensions (stretches between the fingers); and 5) Arm Rotation (execution of chords and octaves). In addition, since factors such as retuning of the instrument., polyrhythms, and improvisation can make a moderate or intermediate piece into a difficult one, a Special Problem category was added.Each of the six physiological divisions are assigned a numerical. difficulty level from one to ten. The divisions are then averaged and assigned a final "grade" as follows:Easy 1 (E-1)=1.0-1.9; Easy 2 (E--2)=2.0-2.9; Moderate 1 (M-1)--3.0--3.9; Moderate 2 (M-2)=4.0-4.9; Intermediate 1 (I-1)=5.0--5.9; Intermediate 2 (I-2)=6.0-6.9; Difficult. 1 (D-1)=7.0--7.9; Difficult 2 (D-2)=8.0-8.9; Virtuoso (V)=9.0.Eighty--six sonatas were reviewed and graded. These compositions represent a broad selection of works of various degrees of difficulty. By knowing the student's abilities and needs, the piano instructor may use this study to select sonatas that correspond to the appropriate level of attainment.Of the works reviewed, the majority fall into the Moderate category. This was not an unusual finding in that certain pianistic development is required before being able to play the scores. The grading system differs from previous systems in that it provides criteria for the placement of the works into a difficulty rating based on the physiological factors affecting the pianist's development.
