ABSTRACT:
BACKGROUND
1. Field of the Invention
This invention belongs to the family of training apparatus, more precisely the ones for music instruments with keyboards, such as a piano, a synthesizer, a harpsichord or an organ.
BACKGROUND
2. Description of the Prior Art
Some patents have drawn our attention:
U.S. Pat. No. 5,753,840, De Albuquerque, May 19, 1998 is a support for the arms and hands of a user of a keyboard, for drawing, or for knitting. It can slide horizontally along a frame and swivel. But it does not allow for quick vertical movements of the hands. A pianist does not have the freedom necessary to interpret a musical piece.
U.S. Pat. No. 5,465,931, Macdouald, Nov. 14, 1995 has a mechanism for relieving stress on the hands of a person operating a computer keyboard. It comprises an adjustable support bar fixed on both sides of a sliding panel on which rests the keyboard. The support bar is in the same plane as two horizontal arms but does not comprise two vertical arms, nor a double adjustment pivot that would allow the removal of the bar. This apparatus cannot support the keyboard of a piano nor be installed under one without modifications.
U.S. Pat. No. 5,158,256, Gross, Oct. 27, 1992 illustrates a pad support for each wrist of a keyboard operator. Two pads slide along the keyboard. The support is constant but is not applicable to a technique where the user only touches the bar lightly.
OBJECTS AND ADVANTAGES
The first objective of this invention is to provide a training bar that helps a pianist take a good posture while playing. To help beginners to always keep the same rectilinear posture guided by the bar. To reduce the tension on the fingers caused by the superior members, by providing a base on which the wrists are placed, thus avoiding tendinitis. An apparatus which is to help building the muscular strength of the fingers, by alternating the support of the wrists on the bar with the non-support, that is the weight of the arms on the fingers. A bar which can be adjusted to different users, giving them a distant position, allowing them to play longer and more quickly with a better control of their fingers, without getting tired. A bar which is to serve as a guide for the blind.
Another objective is to provide a bar made of smooth wood or any to other smooth material, mounted to the ends of a keyboard, a bar which is to comprise means of adjusting the bar vertically and horizontally, means for locking it at the desired position, under a keyboard support structure, and a fast system that allows lowering or adjusting the bar by one stroke of a handle.
Another objective is to develop a method for beginners and pianists at any level. A method which may comprise a series of exercises to do with the training bar.
