Bétøn plays Terry Riley's "in C"
Electronic musicians collective Bétøn interprets Terry Riley's famous piece "in C"
In "In C", all performers play from the same page of 53 melodic patterns played in sequence.
Patterns are to be played consecutively with each performer having the freedom to determine how many times he or she will repeat each pattern before moving on to the next.
Each pattern can be played in unison or canonically in any alignment with itself or with its neighboring patterns.
One of the joys of IN C is the interaction of the players in polyrhythmic combinations that spontaneously arise between patterns.
Some quite fantastic shapes will arise and disintegrate as the group moves through the piece.
Terry Riley
As these guidelines are the basis of the performance, I wanted to translate them in the visuals. I wanted the audience to understand what was going on in front of them.

I took all the midi patterns from the sheet and made them pass by, as in mechanical pianos.

Each performer is represented by its own square, climbing along the score and showing the notes he or she is playing.
