Abstract: A method, computer program product, and system for automatically tuning a stringed instrument. An initial height of a first string of an instrument having a plurality of strings and a floating bridge is determined. The height of the plurality of strings is determined using a bridge sensor. The floating bridge is locked. A frequency of the first string is analyzed. In response to determining the frequency of the first string does not match a predetermined frequency, a tuning peg servo motor to adjust a tuning peg, thereby adjusting a string tension of the first string. The one or more bridge servo motors adjusts a spring tension until the spring tension of the one or more springs equals the string tension of the first string. In response to determining the first string is tuned, the floating bridge is unlocked.

Abstract: A musical instrument support strap is integrated with a tuning sensor having of a body configured at one end for attachment to the musical instrument. The body carries the pitch of a musical note struck on the musical instrument and is detected by a pickup. A printed circuit board converts the detected pitch for display on a liquid crystal display module, preferably having a needle indicator and a color indicator. The sensor may be provided independently for attachment to an existing strap. The method of using the strap for tuning a musical instrument includes attaching the musical instrument support strap to a musical instrument; striking a note on the musical instrument; reading the measurement of the frequency of vibration on the liquid crystal display module; and, adjusting the musical instrument to change the frequency of vibration.

Abstract: A music practice supporting appliance has an input unit that inputs a musical sound of a musical instrument and/or vocal music, converts the musical sound into an electric signal, and outputs the electric signal as an input signal. An amplifying unit amplifies the input signal outputted from the input unit. A processing unit processes the amplified input signal to obtain input signal data. A first memory unit stores the input signal data. A second memory unit stores input signal data stored in the first memory unit when the input signal data stored in the first memory unit exceeds a preselected storage capacity of the first memory unit. A control unit controls the first memory unit and the second memory unit so that while the first memory unit is receiving for storage thereinto new input signal data which causes the first memory unit to exceed the preselected storage capacity, portions of input signal data previously stored in the first memory unit are deleted from the first memory unit and are stored in the second memory unit, and the new input signal data is stored in the first memory unit. A display unit displays the input signal data stored in the first and second memory units.

Abstract: A musical instrument includes a two-dimension array of note producing elements wherein the elements along one dimension of the array have three-quarter steps or increasing fundamental frequencies F.sub.n according to the equationF.sub.n =F.sub.0 *2.sup.n/8wherein F.sub.0 is the fundamental frequency of the first note producing element in the one dimension and n is the number of the note producing element in the one direction from the first note producing element. The note producing elements along a second dimension of the array have fundamental frequencies which differ by frequency differences (such as perfect fourth intervals) greater than the frequency differences between adjacent note producing elements along the one dimension of the array.

Abstract: Disclosed is an electronic musical instrument comprised of operators organized in repeating patterns of seven. The operators are electronically interpreted to correspond only to the valid notes of a selected scale. The repeating patterns of seven notes directly corresponds to the vast majority of mucis theory and thus constitutes an enormous simplification in the art of learning, performing and composing music. The present invention enables users of the electronic musical instrument to master chord and note progressions in any scale and mode by learning only a single set of note patterns, in contrast to the myriad scales, chord and note patterns which must be learned on traditional keyboard and pedal devices.

Abstract: An electronic musical instrument preferably contains a microprocessor-based MIDI controller which receives signals from a standard IBM-compatible computer keyboard as input and processes the signals to reproduce music. A simple but powerful calculation, wherein keypresses indicate diatonic interval changes in pitch value rather than absolute pitch values, converts the signals generated by the sequence of keystrokes into musical tones on an external synthesizer via the MIDI protocol. Relative key signature changes and changes of the base scale (including non-Western scales) are accomplished with the touch of a button or foot pedal. Tone rows can be created and played back, and harmonic configurations ("chords") selected while playing. The keys on the keyboard are initially assigned functions for optimal ergonomic efficiency, but provision is made for the user to custom-design his or her own keyboard layout and scale configurations.

Abstract: Basic frequency data is preliminarily stored in a ROM. Tuning data obtained from a tuning counter according to manual operation of a rotary switch, and basic frequency data out from the ROM are processed in a CPU to form modified frequency data, which is stored in a RAM. The modified frequency data stored in the RAM is selectively read out according to the operation of the keyboard, so that a tuned note sound is produced from a loudspeaker.
