Descripción del instrumento
El piano es un instrumento de cuerda con un teclado derivado del clavicémbalo y martillos y cuerdas derivados del dulcémele. Difiere de sus predecesores sobre todo en la utilización del sistema del martillo impulsado hacia las cuerdas por la tecla, que permite al intérprete modificar el volumen mediante la pulsación fuerte o débil de los dedos.
La extensión del piano primitivo era, como la del clavicémbalo, de cuatro o cinco octavas. De forma gradual se fue aumentando a más de siete. Para ello se realizaron cambios estructurales como el incremento de la tensión de la cuerdas para producir ciertas notas.
