Title (EN) SPRING FOR COMPENSATING THE TORSION PHENOMENON OF THE KEY AND STRING MUSICAL INSTRUMENT CASING
(FR) RESSORT POUR LA COMPENSATION DU PHENOMENE DE TORSION DU BOITIER DES INSTRUMENTS DE MUSIQUE A TOUCHES ET CORDES
Abstract: front page image
(EN)The spring (1) is arranged, with a preset tension, at the bottom of the instrument or onto its supporting parts, so as to correct the deviation of the casing with respect to the horizontal plane, due to the tension of the strings. Hence the hammer, in the keyboard instruments, or the tangent, in the clavichord, strikes again the string at the theoritical excitation point. Furthermore, there is no deformation of the parts of the casing, of the bar and of the resonance table in the clavichord, the virginal, the spinet, the harpsichord, the square piano. Thus, the chord is very well kept in these musical instruments.
(FR)Le ressort (1) est dispose, sous une tension prealable, au fond de l"instrument ou aux parties etayees de celui-ci, de facon a corriger la deviation du boitier par rapport au plan horizontal, provoquee par la tension des cordes. Ainsi le marteau, dans l"instrument a clavier, ou la tangente, dans le clavicorde, frappe a nouveau la corde au point theorique d"excitation. En outre, il n"apparait aucune deformation des parties du boitier, de la barre et de la table de resonance dans le clavicorde, le virginal, l"epinette, le clavecin, le piano carre. On obtient ainsi un tres bon maintien de l"accord dans ces instruments de musique.
