The wearable device includes a plurality of finger sleeves, generates an indication signal on a corresponding finger sleeve according to each second electronic signal.

A device, system, and methods for indicating trombone slide positions is disclosed. Namely, a trombone slide position indicator is provided. In some embodiments, the trombone slide position indicator includes a slide position rod mounted in a fixed position in relation to the outer slide of the trombone. Further, a plurality (e.g., seven) slide position indicators are provided along the length of the slide position rod, wherein the positions of slide position indicators correspond to a certain pitch or note. A sensor guide is mounted to the outer slide, wherein the sensor guide moves with the outer slide and in relation to the fixed slide position rod. The sensor guide includes a mechanism for detecting and/or indicating close proximity to any one of the slide position indicators along the slide position rod. Further, a method of using the trombone slide position indicator is provided.

A tempo trainer includes a plurality of lights displayed on a front display surface of a housing in the form of at least one of a line or a circle and including a center light. A beat can be set for an electronic metronome. An attack from a musical instrument can be compared with the beat using a phase comparator. The difference in phase between the beat and the attack can be determined by the phase comparator. The difference in phase (time-difference) between a beat of an electronic metronome and an attack of a musical instrument can be displayed by the plurality of lights. The plurality of lights can visually display the difference with at least one or a portion of the plurality of lights becoming lit either ahead of, at, or after a center light to indicate whether a musician operating the musical instrument is playing ahead of, at, or after the beat of the electronic metronone.

A computer implemented method for providing feedback of harmonic content relating to a music track, includes receiving music track information; generating harmonic music track parameters based on the received music track information; displaying notation information for a user for performing the music track at a given time for the music track based on the harmonic music track parameters; receiving harmonic user content generated by an instrument performed by the user, using at least one capturing device; generating real-time performance feedback for the user based on comparison of the harmonic user content and the harmonic music track parameters according to predefined settings; receiving reference harmonic user content from a plurality of reference users over a public network; adjusting, based on the reference harmonic user content, at least one of the following: the predefined settings; and the harmonic music track parameters.

In the Play By Number Music Notation System a grand staff is placed on top with multiple keyboard images aligned underneath. Each keyboard image represents one CHUNK of the song (a melodic phrase) and is identified with a letter (A, B, C, . . . ) on the right side and numbers on the left (01, 02, 03 . . . ) to show the sequence each chunk is played. Numbers are placed on the white keys indicating the order the keys are pressed (i.e. 1-12 . . . ) and the duration by using the familiar plain, bold, bold-italic from printing to indicate short, long and longer. When numbers are placed on the line between two keys this indicates you move up the line and play the black key. No need to indicate sharp(#) or flat(b). One simple follows the numbers pressing each key in sequence until the chunk is done.

A computer implemented method for providing an augmented reality (AR) function, comprises receiving input information regarding a music track and an instrument; determining attribute information of the music track based on the received input information; receiving real time content of audiovisual (AV) input signals using at least one capturing device; generating visual information corresponding to visual data of the real time content, wherein the visual information corresponds to a view regarding at least one user limb and an instrument comprising a plurality of user operable elements; generating augmented reality (AR) instruction information based on the attribute information of the music track, the augmented reality (AR) instruction information comprising a plurality of layers; and generating augmented reality (AR) visual information by applying the augmented reality (AR) instruction information to the visual information so that a first layer of the augmented reality (AR) instruction information is applied above at least a portion of the visual information.

A piano co-pilot system for enhancing piano skills of a student, the system comprising: a co-pilot hardware, including: a LED strip having a plurality of LED lights and a listener/interface unit, the listener/interface unit including a processor unit and a touch screen/listener device; a cloud computing center having at least one application programing interface (API) and an artificial intelligence (AI) module, with the co-pilot hardware in communication with the cloud computing center; a piano, which is a keyboard having a plurality of arranged keys; wherein the LED strip is configured on the keyboard with the plurality of LED lights configured to correspond to the plurality of arranged keys; and wherein the listener/interface unit is configured upon the piano and the touch screen/listener device is accessible for visual and tactile interface by the student.

The present invention is a device and method for teaching note locations, fretboard patterns, scales, chords, and songs on the fingerboard of a fretted stringed instrument (fretboard), such as an electric or acoustic guitar, bass guitar, or other fretted instrument. The invention comprises a set of affixable fretboard strips (strips) that adhere to the surface of the stringed instrument, using a mild adhesive or other means of attachment, so as not to damage the instrument, and a number of electronic illuminable markings, such as LED lights, which indicate musical notes and concepts. Once applied to an instrument, an external controller illuminates the electronic illuminable markings in sequence in order to communicate the note positions of notes, scales, chords, playable patterns and songs in order to teach the same to would be students.
