Electronic Etude No. 1 synthesizes sine tones and processes the sounds of a trumpet during a live performance. The processed sounds include the harmonization of the trumpet. This harmonization takes the trumpet’s sound and bends it to create harmonies of 2nds, 3rds, 5ths and octaves above and below the sounding trumpet pitches. The harmonization appears in a number of ways ranging from simple imitation to high-speed, randomized counterpoint. The sine tones create an atmosphere of reflection, while the live trumpet and harmonizations steadily increase in tension to a climactic moment that ends suddenly with a low sine tone. This tone creates a wall that the frantic trumpet and harmonizations run into, stopping the frenzied momentum in its tracks. The closing material is somber in nature with a gloomy reflective sine tone progression ending the work.
