Adapting Literary Ideas to Music: Paraphrase No. 1 for Piccolo and Trombone

At some point in my late adolescence, I watched a presentation on a Brazilian composer who would take literary ideas, such as metaphor, simile or anaphora, and apply them to music. I don't remember the composer or his work; I was more captivated by the concept.

The idea of applying literary procedures to music wasn't completely new to me; I had been experimenting with Surrealist techniques around this time as well, many of which were developed for writing and which I wanted to apply to music, such as automatic writing and exquisite cadaver. But it was that presentation which reinforced its artistic validity in some way for me and inspired me to continue with these types of experiments. Paraphrase No. 1 was one such experiment.

The ideas was to take the idea of paraphrase, which is to say the same thing with different words, (hm....the definition of paraphrase is itself a paraphrase of paraphrase...), and apply it to music. I chose two instruments. The idea would be to have both of them use the same melody, with the same pitch structure, dynamics and articulation, but varying the rhythm, perhaps the key, and other possible parameters. I chose a piccolo, which has the highest register, and the trombone, which has one of the lowest (I don't recall why I didn't choose the tuba). They are both metallic instruments, but at opposite ends of the register, which I found amusing and good for contrast.

My friend Mariaceli Navarro performed this piece with Alonso Olvera on her Piccolegio Youtube channel. Here is the result:
