b) dos placas laterales 5 y 6, de forma rectangular. Cada una presenta en su lado vertical delantero una parte rectangular saliente 7 en su altura media (correspondiente al teclado) y opcionalmente una parte rectangular 8 de reducida altura (corresponiente al suelo); dichas partes horizontales están opcionalmente relacionadas por las columnas 10;  b) two side plates 5 and 6, rectangular in shape. Each one has on its front vertical side a projecting rectangular part 7 at its average height (corresponding to the keyboard) and optionally a rectangular part 8 of reduced height (corresponding to the ground); said horizontal parts are optionally related by columns 10;
c) la base rectangular y horizontal 9 del teclado, desstinada a quedar sustentada por sus extremos por las caras laterales 2 y 3 mediante los elementos que se indicarán; frontalmente presenta la barra embellecedora 14;  c) the rectangular and horizontal base 9 of the keyboard, intended to be supported by its ends by the lateral faces 2 and 3 by means of the elements to be indicated; frontally it presents the trim bar 14;
d) la placa alargada inferior 11 sobre el suelo, provista de orificios 12 en su parte central para el paso de los pedales 13.  d) the lower elongated plate 11 on the floor, provided with holes 12 in its central part for the passage of the pedals 13.
Las placas laterales 5 y 6 se acoplan e inmovilizan respectoa las caras laterales 2 y 3, respectivamente.  The side plates 5 and 6 are coupled and immobilized with respect to the side faces 2 and 3, respectively.
Los extremos de la placa base 9 del teclado incorporan sendas guías horizontales 15, conjugadas de unos soportes 16 asimismo horizontales en las partes internas de las caras 2 y 3.
