Ensemble SCALA: the Night of the Microtone
composition ‘i m p r o s p e c t r u m’

“It is an honor to introduce the last piece of this concert, of this festival. It’s a collective improvisation in Just Intonation based on the addition chords of Adriaan Fokker. For the mathematicians and numberphiles – and I know you are here – it is in 433-limit Just Intonation. And that is a significant number. 4’33 is the name of the bar downstairs and I hope to see you all there after the concert!”
