Abstract
A chair specifically engineered for performing musicians is disclosed. Extensive research and design has produced a vocal or instrumental musician's chair which permits proper diaphragmatic breathing and on which a musician can sit comfortably for long periods of practice or performance. This result is achieved by contouring the seat both for correct performing posture and for comfort. The orientation of the back-rest of the chair to the seat also enhances the posture of the performer and this, in conjunction with the positioning of the body relative to the floor, contributes to the ability of the performer to breathe properly while seated comfortably, thus reducing fatigue and greatly enhancing the tonal quality of the performance.
Claims15
A chair for a performing musician having a chair seat, a backrest and means for supporting the chair seat in a fixed position above the floor establishing a height of the chair seat, the improvement comprising:
- a chair formed with a plurality of general support planes including two laterally spaced coincidental general support planes for the thighs of the performer and a central support area forming a general support plane for the pelvis of the performer;
- and wherein
- the height of the chair seat permits the musician to have both feet flat on the floor;
- the general support plane for the thighs is no more than three degrees above horizontal to ten degrees below horizontal from back to front and in combination with the height of the chair seat causes the thighs of the performer to slant forward toward the floor to open the angle between the abdomen and legs of the performer to enhance diaphragmatic breathing;
- the general support plane for the pelvis comprises an area lying along the longitudinal center line of the chair seat having a lateral dimension along the back of the chair seat of no more than six inches and a lateral dimension at the front edge of the chair seat of no more than two inches which is contoured to form a middle ridge along the center line of the chair seat;
- the general support plane of the pelvis is inclined at least three degrees above the general support plane for the thighs of the performer from back to front to cause the pelvis of the performer to be rotated forward to relax muscle tension caused by improper support of the upper body of the performer;
- and wherein
- the backrest is positioned so that the center line of the backrest intersects the general support plane for the thighs at an angle within the range of ninety-one to one hundred twenty-five and intersects the general plane for the pelvis at the back edge of the general support plane for the pelvis so that the back of the performer is precisely positioned relative to the general plane for the pelvis in a natural and relaxed sacrolumbar curve so that the organs and upper body weight supported by the spine of the performer are in balance.
