Vexations

This piece was written by Erik Satie. the title is Vexations, meaning literally "harassment".. Because this piece is consists of a short chordal passage, and is intended to be repeated 840 times. On the score, it's written that
"Pour se jouer 840 fois de suite ce motif, il sera bon de se préparer au préalable, et dans le plus grand silence, par des immobilités sérieuses":
"In order to play this motif 840 times consecutively to oneself, it will be useful to prepare oneself beforehand, and in utter silence, by grave immobilities."
Wow.., it must be the original of the minimal music. the sound is so simple and I like it.
