Abstract

A hybrid acoustic piano, specifically a piano the wires whereof are struck, of the type including a grouped wires, where of each group of three or of four wires associated with a key, one of these is tuned at a pitch different from the other two or three, which are tuned identically; and where the mechanism is such that when the pedal is in a resting state, that is, without depressing the pedal, on pressing the keys, the hammers strike at least two wires of the three or of the four wires of each group with the same tuning, and when the pedal is depressed, the mechanism displaces the hammers to the right and, on pressing the keys, three wires are struck, one of which is the wire tuned at a different pitch from the others.

Description

OBJECT OF THE INVENTION The invention, as stated in the title of the present specification, relates to a hybrid acoustic piano which contributes, to its intended use, advantages and features, which are described in detail further on and which imply a novelty for the current state of the art. The object of the present invention relates to a piano, specifically a traditional piano the wires whereof are struck, and preferably a grand piano, but without ruling out that it could be an upright piano, which is distinguished by having a mechanism for displacing the hammers associated with a pedal, usually the left pedal, which is modified in such a way that, on pressing said pedal, instead of causing the attenuation of the sound of the key or keys being played, it causes a change in the timbre of their sound, for example an accordion tuning, thanks to the fact that, in turn, one of the three or four wires associated with each key, at least in some of them, is tuned at a different pitch from the others. FIELD OF APPLICATION OF THE INVENTION The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of musical instruments, focusing particularly on the field of pianos. BACKGROUND OF THE INVENTION As is well known, one of the pedals of traditional pianos, the wires whereof are struck, usually the left pedal on grand pianos, also called “single wire pedal”, performs a sound attenuating function. To do this, the hammer mechanism of the piano works in a way that it is displaced a few millimeters to the right, whereby, when said pedal is pressed, the hammers touch fewer wires and therefore the piano's sound is less. It must be borne in mind that most piano keys correspond to three wires grouped together struck by the hammer corresponding to their key. This pedal is often used to make pianos (soft) although it is also used as a nuance of color and sonority. In addition, there are also some traditional piano models that comprise groups of four wires associated with one key, usually in the highest-pitched keys. In such a case, however, the hammer mechanism strikes only two or three of the wires in each group, depending on whether or not the attenuation pedal is pressed, while the fourth wire, in addition to being fastened to a different element from the one that keeps the other three wires attached together located at a different height, its sound is only due to a sympathetic vibration effect, since the hammer never strikes it. The objective of the present invention is to provide a new type of piano in which, taking advantage of the same pedal system and associated mechanism to cause the displacement of the hammers, said attenuating function is replaced with an innovative function that allows a traditional piano sound to be transformed into an acoustic sound, so that the piano becomes a hybrid instrument that allows being played in both modes interchangeably. Today there are countless musicians looking for new timbres to vary the sounds and harmonies of their works. The present invention is, therefore, an interesting proposal for composers of any genre, but especially for composers and musicians of jazz, contemporary music and all those who work with improvisation, since it increases the diversity of piano sounds by adding new harmonies. Moreover, as a reference to the current state of the art, although innumerable types and models of pianos are known, at least the applicant is unaware of the existence of any other piano which has technical features equal or similar to those had by the one claimed herein. DESCRIPTION OF THE INVENTION The hybrid acoustic piano proposed by the invention is configured as the ideal solution to the aforementioned objective, the characterizing details that make it possible and that distinguish it being conveniently included in the final claims that accompany this description. Specifically, as noted above, the invention proposes a piano the wires whereof are struck, preferably a grand piano, which is distinguished by having a mechanism for displacing the hammers associated with one of its pedals, usually the left pedal, which is designed in such a way that, on pressing said pedal, instead of causing the attenuation of the sound of the keys being played, it causes a change in the timbre of the sound, for example an accordion tuning, since, in turn, one of the three or four wires associated with each key, at least in some of them, is tuned at a different pitch from the others. This invention is generally carried out on the piano part where each note has 3 or 4 wires, that is, from key 30 to key 88, more or less. The low keys, from key 12 to key 30 or so, can also be tuned as the invention proposes, although the new timbre in the low keys is not as pleasant as in the high keys. Normally, in traditional pianos existing until now, when the pedal is depressed, the mechanism with which it is associated causes the hammers to be displaced a few mill
