Joseph Carrillo composed this peice to test GPO when he first received it. He writes: \"I wanted to write something which allowed me to test out a lot of the instruments at once to see how they work individually and together; and also allowed me to see how GPO handled a variety of emotional textures.\"
I think by monophonic you mean homophonic (please correct me if I\'m wrong), and yes there are moments when the strings are playing chords to support what the winds and brass are doing. And visa-versa. There are also a couple of moments of divisi in the 1st Violin and 2nd Violin sections.
I actually composed the score in Finale, and then ported it over to Digital Performer (v.4.11 for those who are interested) to program in everything.
Hopefully I\'m on the right track on answering your question, here... I didn\'t really go to school to learn composition, I just started writing. Looking back, I wish I had; I\'d probably have a better handle on harmony and a better sense of structure. Although my intention with this demo was to better aquaint myself with GPO, I always write with the idea that living breathing musicians will perform whatever I\'m writing. Also, understanding how the instruments work individually, and in the context of an orchestra is also important.
