  • Patent number: 7115806
    Abstract: A teaching aid for instructing proper finger position on a “fret-less” stringed instrument (for example, violin, viola, cello, bass) comprises a template that is positioned along the fingerboard at the proper finger position location (i.e., “first position”) for the first four half-steps associated with each string. A set of raised, “Braille-like” features is formed as a grid pattern on the surface of the template, with each row of features associated with each tone half step. Each “row” contains a set of three raised features—a separate feature located between an adjacent pair of strings. Once the template is properly positioned, the raised features are pressed out of the template and transferred to adhere to the fingerboard. By locating the raised features between the strings, the teaching aid does not interfere with sound quality or the ability to induce vibrato to the playing, while still providing a tactile clue for the proper note location for intonation purposes.

  • Patent number: 6924426
    Abstract: A method for the algorithmic expressive intonation tuning (EIT) and performance of electronic, computer and MIDI musical works relies on melodic intervals, rather than on chordal harmony, and acts by desirably modifying the pitch of a note slightly (compared to equal temperament tuning), depending on the next melodic note. This dynamic, non static, melodic tuning emulates, and can even possibly augment, aspects of outstanding live human musical performance achieved with regard to pitch subtleties, as it enhances the living sounding, real aspects of the performance of electronic, computer and MIDI music, by sensibly causing a slightly different pitch of particular notes, depending on the size of an interval and on whether an interval is ascending or descending, with the same note subtly having more than one pitch often, depending on melodic context.

  • Patent number: 6473723
    Abstract: A mimic filter which can be implemented in analog or digital circuitry, and which removes dc offset or other noise from an input signal using a pseudo-differentiation technique. The input signal is adjusted by a feedback value, and the adjusted signal is amplified by a proportional gain factor to generate an output signal. The feedback value is determined by integrating the output signal and multiplying the integration by an integration gain factor. The mimic filter avoids the generation of false signal spikes.

  • Publication number: 20020124712
    Abstract: An operation apparatus is responsive to a physical action for inputting a control parameter of a musical sound into an electronic musical instrument. The operation apparatus is provided with a plurality of movable members individually responsive to the physical action to undergo a reciprocal movement. A frame mounts the plurality of the movable members in aligned manner. A tension member having a length is supported at both ends thereof by the frame to extend along the movable members such that each movable member may come into contact with the tension member during the course of the reciprocal movement of each movable member. A detector is connected to the tension member for detecting a deflection of the tension member caused by the contact of the movable member, and generates a signal corresponding to the detected deflection as the control parameter.
