Composition 2020.19 (Untitled) is forty-two minutes and forty seconds in duration - and was produced digitally using FM and physical modelling synthesis. The components of the composition were produced by two digital instruments - and with eight tonal sounds from each. The tones occur simultaneously to produce dyads. These sounds are sixteen bars long - and repeat every thirty-two bars. The eight tones for instrument one (sinewave-based) are C3 - C#3 - C3 - C3 - C3 - C3 - C3 - B2. And the eight notes for instrument two (electric piano) are C2 - C2- C2 - B1 - C2 - C#2 - C2 - C2. These two eight-note sequences - which are two-hundred-and-fifty-six bars long - are repeated five times throughout the composition. In addition - there is a low-frequency sound - pitched at C1 - that continues throughout the duration of the composition.
