Abstract:
A music performance feedback tool is described herein that enables a musician to play freely and receive feedback in real-time. The tool tracks the musician as they progress through a piece and returns optimal feedback given an input sequence produced by the musician. The tool enables musicians to practice in a fashion that is most natural and pedagogically correct. The tool provides musicians with annotations indicating what notes in the score they failed to play, erroneously added notes, and the like. The tool further provides the musician with tempo and rhythmic feedback.
Abstract:
A system 100, for determining the velocity of a hammer 120 of a keyboard instrument, with a light transceiver 140 and processing circuitry 160. The light transceiver 140 being configured to transmit a light signal to a hammer 120 to measure a hammer velocity, receive a reflected light signal from the hammer 120 indicative of the velocity of the hammer 120 and send an electrical signal to the processing circuitry 160, where the electrical signal is based on the reflected light signal from the hammer 120. The processing circuitry 160 being configured to receive and process the electrical signal so that a time interval between the electrical signal passing through a first trigger point and a second trigger point and the velocity of the hammer 120 can be determined.
Abstract:
A vibration detection mechanism includes: a first sensor section that detects vibration of a vibrating member of a musical instrument in a first direction being a main vibration direction; a second sensor section that detects vibration of the vibrating member in a second direction being approximately perpendicular to the first direction; and a third sensor section that detects vibration of the vibrating member in a third direction being approximately perpendicular to both the first direction and the second direction. Sensitivity of the second sensor section is greater than sensitivity of the first sensor section. Sensitivity of the third sensor section is greater than the sensitivity of the first sensor section.
Abstract:
In at least one embodiment, a method of performing automatic transcription of musical content included in an audio signal received by a computing device is provided. The method includes processing, using the computing device, the received audio signal to extract musical information characterizing at least a portion of the musical content and generating, using the computing device, a plurality of musical notations representing alternative musical interpretations of the extracted musical information. The method further includes applying a selected one of the plurality of musical notations for transcribing the musical content of the received audio signal.
Abstract:
A method for transcoding music, according to various aspects of the present invention, includes in any practical order: (a) reading pitches and respective durations; (b) reading indicia of a quantity of beats per measure; (c) determining a word for each beat wherein: each word has one or more syllables, each syllable is associated with each pitch having duration that is within the duration of the beat; each syllable for a pitch, when preceded by a rest, comprises an initial consonant selected from the set consisting of ‘d’ and ‘t’; and each syllable comprises a vowel corresponding to an ordinal of the beat, wherein the vowel is selected from a set of vowels in accordance with the respective duration of the pitch associated with the syllable; and (d) outputting, for use by a music engraving engine, indicia of the pitches and words, in a manner that each syllable will be engraved in vertical alignment with the indicia of the associated pitch.
Abstract:
Embodiments generally relate to sensing key press activation. In one embodiment, a method includes providing a signal in an electronic device. The method further includes causing the signal to reflect off of a key of the electronic device. The method further includes determining a movement of the key based on a reflection of the signal.
Abstract:
An elongated lifting rail is displaceable to collectively pivot a plurality of damper levers. An actuator is provided beside or underneath the lifting rail for automatically displacing the lifting rail. The lifting rail is displaced, in response to driving of the actuator, to displace the damper levers so that the dampers are moved away from contact with sounding members. Further, a position sensor is provided for detecting a displaced position of the lifting rail, so that position data detected by the position sensor is used for operating position control and/or operating position recording of the dampers.
Abstract:
There are provided an image acquisition unit acquiring an image containing information of a paper-based musical score from an image reading-out unit, and a musical character recognition unit recognizing a musical character contained in the image acquired by the image acquisition unit by using a plurality of musical character recognition methods, and outputting a plurality of musical character recognition results.

Abstract:
A signal processing apparatus subjects an audio signal to musical pitch analysis using different analysis techniques for the higher and lower frequencies. When an audio signal is input, a first extractor extracts a high-frequency signal, and a second extractor extracts a low-frequency signal from the audio signal. A high-frequency processor extracts pitch components from the high-frequency signal by applying the short-time Fourier transform. A low-frequency processor extracts pitch components from the low-frequency signal by dividing the low-frequency signal into a plurality of octave components. A synthesizing unit then combines the pitch components thus extracted from the high-frequency signal and the low-frequency signal and outputs the analysis result.
