It was conceived from my personal interest in creating a musical narrative that could create different moods, colors, contrast, agreement, tension, and resolution. I had a major influence from Ligeti’s Double Concerto regarding pitch, mood and form organization. I used his technique of interval signal to differentiate different sections of a movement as well as chromatic balance─the alternation of diatonic scales related chromatically. I also had influences from Mahler, Debussy, Nancarrow, and from my own work. The narrative of my Concerto is based on Ligeti’s notion of states, events and transformations. My Concerto presents states that are transformed into new states. The piece is divided in four movements: Lights, Convergences, Lights II, Convergences II. The Lights movements favor delicate texture, based on a major melodic line and a subtle accompaniment. They also give prominence to solo sections. Convergences favors the idea of dialogue, multitudinousness, contrast, and dense textures. Convergences II emphasizes the tutti versus solo and ritornello form from Baroque concertos.application/pdfengMusic compositionOrchestraConcertoAnalysisLigetiMusical narrativethesis2011-08-012152/ETD-UT-2011-05-2780
