Heu sentit com sona el nombre pi? A partir d’un treball conjunt entre Tecnologia, Matem\u00e0tiques i M\u00fasica, els alumnes de 1r A l’han fet sonar.
\nDespr\u00e9s de con\u00e8ixer el nombre PI i les seves xifres decimals infinites\u00a0des de Matem\u00e0tiques, M\u00fasica va recollir-ho per estudiar les escales musicals. A cada xifra de pi, se li pot assignar una nota de l’escala de Do major (i en reservem una pels silencis). Per la durada, la soluci\u00f3 m\u00e9s senzilla: fer-la aleat\u00f2ria (negra, rodona o corxera).<\/p>\n

A partir d’aqu\u00ed, i aprofitant que a Tecnologia estem treballant la programaci\u00f3 inform\u00e0tica amb Scratch, els alumnes han creat el programa que fa tot el proc\u00e9s i produeixi els sons.<\/p>\n

L\u00f2gicament, la melodia que obtenim no \u00e9s especialment bonica, ja que no segueix cap harmonia. Per\u00f2 si que ens introdueix a la m\u00fasica aleat\u00f2ria.<\/p>\n

Podeu escoltar-ne un parell d’exemples a continuaci\u00f3:<\/p>\n\n\n\n\n
