Wodnesdaeg

Wōdnesdæg is sixty-four sine waves tuned to one chord and left to ring. Nothing is triggered, nothing decays. The instrument is the chord itself, and what you hear is the beating between waves. Two banks of sixty-four sliders run across the screen. The upper bank is how loud each wave is. The lower bank is how far each wave sits off its own note. Sitting exactly on the note, sixty-four waves have nothing to beat against and the chord is flat. Move one and a slow pulse appears. Move twenty and the chord starts to breathe. TEMPER sets the tuning system, so the same chord can be equal-tempered, just, or anything between — and the difference is audible immediately, because sustained sine waves show a tuning system more plainly than any other sound. Choose key, scale and how the chord is stacked. Set the spread of each band. PLAY steps the music through a sequence; the microphone can step it…
