Reflecting on structure and orchestration and the exercise done, the instruments applied in every section of the work are different to provide variety. An example would be in section A, the flute is used for the melody, and in the following section, the oboe is used instead. In some longer sections, an alternation of both instruments exists. Also, there is a blend of both instruments, and the composer also applies solo instruments for what seems to be a different colour blend. In the diagram, the colours mirror every section of the orchestra. Analysing the diagram will show that the string section is continuously engaged along with one or more instruments. The melodic line is light in texture at the beginning and thick as the work progresses. This melody transitions from flute to oboe back and forth and, in later sections, is performed by the strings and sung by the choir. The harmony is shared by the horns, bassoons, and strings. There are episodes of tutti performance, reflected at the end in the J section, where the orchestra’s power is established. Completing the structure and orchestration of the piece has shed light on the variety of sounds and colours achievable by adding or subtracting instruments from the orchestra. Many elements, of course, would have been considered, for example, the power of the horns in loud dynamics, the blending of strings and flutes as an example and the thickness and harmonic progression. By exploring the piece and orchestration, I have gained an incredible insight into how two simple parts (melody and harmony) can be transformed and exploited by the extra components, dynamics, and techniques, to create more expressive statements.
