Patent number: 7259311Abstract: A mobile communication terminal provided with a tuning function, which saves a player the trouble of carrying around a tuning meter or the like and facilitates the tuning of instruments. A user designates a reference pitch stored in a memory, and inputs the sound of an instrument or a voice into a microphone. A synthesizer generates a sound that most approximates the sound input through the microphone according to the reference pitch designated by the user. The sound generated by the synthesizer is compared with the sound input through the microphone, and the result of the comparison is displayed on a display.Type: GrantFiled: March 8, 2005Date of Patent: August 21, 2007Assignee: NEC CorporationInventor: Kazumasa Ashida

Patent number: 7212130Abstract: A sound intensity display system for use by performers. The invention is a system which displays indications of sound intensity on a display large enough to be viewed by performers distant from the display. This invention allows indication of a sufficient number of different sound intensity ranges to make the system useful for performers including, but not limited to, musical performers. In a particular embodiment of the invention, the display face is permanently marked with “ppp” and “fff.” In that embodiment, vertical variable display elements styled as line segments can be selectively illuminated by light emitting diodes based on the sound intensity. This embodiment includes a built in microphone and a female jack connection to allow the optional use of an external microphone. That embodiment can be battery powered or powered by an external power supply through a jack-connection, at the option of the user. Other embodiments include ones capable of receiving and displaying inputs from multiple channels.Type: GrantFiled: September 3, 2005Date of Patent: May 1, 2007Inventor: Carol Hawthorne Bullard

Patent number: 7115806Abstract: 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.Type: GrantFiled: October 12, 2004Date of Patent: October 3, 2006Inventor: Randy Holland

Patent number: 6924426Abstract: 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.Type: GrantFiled: September 30, 2002Date of Patent: August 2, 2005Assignee: Microsound International Ltd.Inventor: Manfred Clynes

Publication number: 20020124712Abstract: 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.Type: ApplicationFiled: March 4, 2002Publication date: September 12, 2002Applicant: Yamaha CorporationInventor: Ichiro Osuga

Patent number: 6437226Abstract: The present invention provides a method for automatically tuning a stringed instrument including the steps of inducing a signal on a string under tension to generate a resonance signal having an amplitude from the string and adjusting tension of the string in response to the amplitude of the resonance signal. The present invention also provides a system for automatically tuning a stringed instrument including a string, tensioning means operably attached to one end of the string for tensioning the string, and a processor for driving the tensioning means to induce a signal on the string and generate a resonance signal having an amplitude from the string and for adjusting tension of the string in response to the amplitude of the resonance signal.Type: GrantFiled: March 7, 2001Date of Patent: August 20, 2002Assignee: Viking Technologies, Inc.Inventors: Mark Oudshoorn, Jeff Moler, R. Glenn Akhavein

Patent number: 6323408Abstract: Templates are used in methods of improving the perceived intonation of musical notes by modifying each note to provide certain frequencies between adjacent pairs of notes. The template modifications provide, in a sequence of twelve notes per octave, or extended octave, that each note is separated from an adjacent note according to one of frequency ratios of 25/24 (h), 16/15 (m) and 27/25 (s). The templates can be used with keyboards and virtual keyboards and applied to recorded music, musical input signals, or data, as required.Type: GrantFiled: February 29, 2000Date of Patent: November 27, 2001Inventor: Chi Fai Liu

Patent number: 6294719Abstract: A string winding device for winding and unwinding the string on a peg of a stringed instrument has a generally cylindrical body with a slot extending inward from one end thereof. The slot has a plurality of sections, which are configured to engage different size and shape pegs on stringed instruments. The slot has a shallow and wide section, a deep and narrow section and a middle section of medium depth and width. A fourth section is located perpendicular to the other three sections and is configured for specialty tuning pegs. Extending from the top of the string winder body is a hexagonal shaft for engagement with a cordless screwdriver, drill or one of the hubs or cranks disclosed herein. A manual hub or crank with a handle may be used to turn the string winder body. The hub of the crank for the manual hub may utilize a flexible tab within the hub to interlock with a recess in the hexagonal shaft to hold the parts together during use.Type: GrantFiled: October 20, 1999Date of Patent: September 25, 2001Inventors: Thomas L. Palecki, David R. Jeffrey
