Mental note: To extend good mood, wear it on when going out from home.
Xul believed that the pianos were uncomfortable to play, as it forced to extend the arms too much: “it would be better to have a piano with several levels making it easy to play the instrument”. And that was how he made it: he divided his wife’s piano into three ranks and colored the keys red according to their vibration, so it could be easier to study. Each note corresponded to a color range, allowing to execute a movement according to the chromatic palette. Would a Pantone help him to refine it?
