Abstract

La présente invention a pour but de proposer un piano droit avec lequel un avantage est disponible, par une nouvelle configuration de marteau, sous la forme de la capacité du piano droit à être installé dans des emplacements étroits. Un autre but est de permettre l'amélioration des faiblesses du piano droit consistant en une expression pauvre du toucher et une capacité de performance insuffisante, par amélioration de la configuration par laquelle le centre de gravité des marteaux est établi, et améliorant ainsi la sensation après toucher et d'échappement, ce par quoi des changements délicats du volume tactile du piano sont ressentis. En plus de configurer les marteaux avec des queues et têtes de marteau, les queues sont formées à partir de queues verticales et de queues horizontales. Les queues verticales se dressent sur les extrémités arrière supérieures des queues horizontales situées orthogonalement à celles-ci, et les têtes de marteau sont disposées sur les extrémités supérieures des queues verticales.
