Abstract
A device for continous pitch variation has rotary support means which connect the extension piece of the neck flexibly with the body of the instrument. A string holder is mounted on one rotary support lever and has adjustable holding elements for each string. A system of levers transmits the tension of the strings over an adjustable point of force transmission to a tension spring. The tension spring has an adjustable seat.
Claims6
A stringed musical instrument comprising:
- a neck, a body, and a plurality of tuned strings extending over said neck and body, said neck having an extension extending into said body;
- rotary support including at least one support lever pivotally connected both to said body and said neck extension to rotate about a body rotation axis and a neck extension rotation axis, respectively, said rotary support means being so arranged that said neck extension may move longitudinally relative to said body to rotate said support lever;
- string holder means firmly mounted on said support lever for holding one end of said strings, said string holder means rotating with said support lever about said neck extension rotation axis to vary the tension of said strings;
- and
- compensating means connected to said neck extension and said support lever for zeroing the torque on said support lever created by the tension of said tuned strings.
