The Concierto Romántico for Piano and Orchestra is one of Manuel M. Ponce's outstanding compositional accomplishments from his Romantic period, reflecting both the state of Mexican music at the turn of the 20th century, and his early nationalist tendencies. However, it remains the only concerto in Ponce's output in need of a more comprehensive analysis. This treatise focuses on a global investigative that examines descriptive and analytic references to the work, as well as a comparison and clarification of the existing score sources. An analytical and stylistic musical study using conventional theoretical techniques leads to a musicological interpretation of the work's extra-musical meaning, based on close assessments of Ponce's compositional practice and social principles.

The Piano Sonatas of Rodolfo Halffter (b. 1900, Madrid, Spain) represent an important body of literature not widely known nor understood for their historical importance and Spanish heritage. The entire development of Halffter's compositional style, which embraces three periods of composition, may be traced through these sonatas. The modes of composition may be seen not to be separate and distinct but as having inter—relationships which therefore affect the outcome of Halffter's final dodecaphonic technique. The culmination of his serial method is found in the Tercera Sonata, op. 30. At first glance, this work appears to be a radical departure from the former styles. However, a more in-depth study reveals this sonata to be the logical outgrowth of earlier compositional techniques, thereby blending diverse, eclectic elements into a unique and homogenous application, all Halffter's own. Forced to flee his native country in 1939, Halffter became the first composer in Mexico to use twelve-tone techniques. Together with Carlos Chavez, he exerted great influence on the present generation's group of Mexican composers. Halffter today remains a crucial link in the continuation of the Spanish tradition as exemplified by his former mentor, Manuel de Falla. A brief explanation of Falla s theory of resonance …
