Title (EN) TWINPIANO
(FR) PIANOS JUMELES
Abstract:
(EN) Two grand pianos are 'twinned' by the COMBI-CHASSIS {D} assemblage which conveys the sympathetic vibrations from one piano to the other; resonance of the second Piano is captured totally, without any perpendicular loss and accurately reflected by the TWINLID {A}; unimpaired reverberation is attained while the potential sonority is intensified to more than twofold; a homogeneous balance is established pertaining to the resonances of both pianos; indigenous disadvantages of halls or studios are converted into advantages with the versatile functions of a tractable JACKING SYSTEM {C} and a multi-purposed, variable ACOUSTICAL FLAP {B}, both of which induce precisely desired reflections of sonorities which are compiled and resonated via the 'shell principle'.
(FR) Deux pianos à queue 'jumelés' au moyen d'un ensemble formant châssis combiné (D) transmettant les vibrations de résonance d'un piano à l'autre. La totalité de la résonance du second piano est captée sans pertes perpendiculaires, et réfléchie avec précision par un couvercle commun (A). On obtient une réverbération inaltérée et la sonorité potentielle est plus que doublée. Un équilibre homogène est établi entre les résonances des deux pianos. Les défauts inhérents aux salles ou studios deviennent des avantages grâce aux fonctions multiples d'un système à vérin extensible (C) et d'un volet acoustique variable polyvalent (B) qui induisent tous les deux des réflexions précises voulues des sonorités dont l'association et la résonance se font selon le principe dit des coquillages.
