Como funciona o piano?<\/p>\n
<\/p>\n
A maioria dos pianos tem 88 teclas, 52 brancas e 36 negras.<\/p>\n
Cada tecla do piano est\u00e1 ligada a um martelo, que \u00e9 de madeira e est\u00e1 coberto de feltro. Ao tocar uma tecla, o martelo bate num grupo de cordas que s\u00e3o no total 230.<\/p>\n
O tom (o agudo ou grave que \u00e9 o som) de cada corda depende do comprimento desta e se esta est\u00e1 mais ou menos tensa. As cordas curtas e delgadas d\u00e3o um tom mais alto que as longas e grossas.<\/p>\n
Quanto mais tensa estiver a corda, mais alto ser\u00e1 o seu som. Algumas cordas est\u00e3o cobertas de arame, para que vibrem mais lentamente.<\/p>\n","protected":false},"excerpt":{"rendered":"
