Arc of the Sky. (Original composition);
Martin, Lee Hall
Master of Music
This is a multi-sectional orchestra piece using melodic and harmonic material derived from a twelve-tone row (although serial techniques are not employed in a strict fashion). The opening oboe line contains the original row and is the germ from which all melodies develop; pyramiding brass clusters act as a reoccurring motive. The piece is written in a symmetrical arch form containing nine sections (ABCDED$\sp\prime$B$\sp\prime$C$\sp\prime$A$\sp\prime$). Section A is an exposition of the primary themes and motives; section B uses melodic variations accompanied by homophonic string chords; section C deals with texture; section D presents echoing motives accompanied by clusters in the strings and woodwinds; and section E leads to the climax by developing themes contrapuntally. Sections D, B, C and A are then recapitulated using variations.
