Systems, devices, media, and methods are described for presenting a tutorial in augmented reality on the display of a smart eyewear device. The system includes a marker registration utility for setting a marker on a musical instrument, a localization utility for locating the eyewear device relative to the marker location and the instrument, a virtual object rendering utility for presenting a series of virtual tutorial objects on the display near one or more actuators on the instrument, and a hand tracking utility for tracking the performer's finger locations in real time during playback of a song file. A high-definition video camera captures sequences of frames of video data. The series of virtual tutorial objects, in one example, includes graphical elements presented on a virtual scroll that appears to move toward the instrument at a speed correlated with the song tempo. The hand tracking utility calculates a set of expected fingertip coordinates based on a detected hand shape and a library of hand poses and landmarks.

There is provided an information processing device, an information processing method and a program that provide, as feedback to a user, information based on a level of collaboration of multiple movement elements in a performance provided by collaborative or non-collaborative moves of multiple parts of a body of the user and that are usable to support mastering a performance. The information processing device includes a sensing data acquisition unit configured to acquire multiple sets of sensing data from at least one sensors configured to sense a condition of multiple movement elements in a performance that is performed because multiple parts of a body of a user move; a calculator configured to calculate collaboration information representing move collaborativeness of the movement elements from the acquired multiple sets of sensing data; and a notification unit configured to notify the user of feedback information based on the calculated collaboration information is provided.

A chord and/or note assist assembly includes a chord and/or note forming aid having a plurality of multi-position string engaging assemblies that engage strings of a guitar in a controlled manner so as to define chords associated with playing a guitar and an extension device having a plurality of multi-position string engaging assemblies that engage strings of a guitar in a controlled manner so as to define chords associated with playing a guitar. An electronic microprocessor circuit board is electrically linked to a solid-state memory to control the plurality of multi-position string engaging assemblies of both the chord and/or note forming aid and the extension device.

A smart training accessory connected to musical instrument for aiding users in learning and collaboration is disclosed. The accessory includes a plurality of sensors for collecting data pertaining to the musical instrument. A microcontroller processes the data collected by the plurality of sensors to: (a) determine a type of musical instrument to which the smart training accessory is connected and (b) generate an alert for encouraging an individual to play the musical instrument when the user enters a monitoring area within the vicinity of the smart training accessory. Furthermore, when the user plays the musical instrument, the plurality of sensors captures data including audio recordings and transmits the data to a training and synchronization system. The training and synchronization system processes the received data to generate real-time feedback for the user and further aids collaboration with other users.

A recommend apparatus includes: a communication device; and at least one processor. The at least one processor is configured to: receive performance information generated based on a performance of a first user, through the communication device; determine a second user from a plurality of other users based on the received performance information of the first user, the second user being at least one of other users similar to the first user in music use tendencies, other users similar to the first user in function use tendencies shown during playing, and other users similar to the first user in music mastering characteristics determined from distributions of scores each of which is calculated for each play; determine recommendation information to be provided to the first user, based on performance information of the determined second user; and send the determined recommendation information from the communication device.

System, methods and devices are developed for the improvement in the dynamic performance of music players in relation to the musical instruments with the DAMONN music notation system. The DAMONN music notation system creates a simple and efficient environment revolving around alphanumericals on the music staves to enable people of all ages of any race to learn a sheet music of any musical instrument easily. The system, methods and devices of the DAMONN music notation system had been adapted for keyboard, string, brass, woodwind, and percussion instruments for ease of reading, writing, teaching and learning music intuitively.

The present invention relates to a music chords conversion device. The device is used for providing instant representation showing conversion or correlation of major chords to minor chords and vice versa. The device can come in two variants (1) a physical device (2) a digital device. The physical device has a chords conversion component and a minor chords component wherein the minor chords component is configured to slide into the chords conversion component through a cut-out opening. The minor chords can be correlated to the major chords and displayed in a viewing region of the chords conversion component. The digital device includes a memory for storing the chords conversion and also includes a digital display for displaying the converted minor and major chords.

In one aspect, provided herein is a device for notating a musical composition. The device, in various implementations, is structured so as to be less laborious to notate, easier to read, and more simple to employ in notating, reading, and/or playing the music of a given composition to be composed and/or played. Accordingly, in its most basic form, the device herein disclosed includes a template, upon which template one or more symbols may be notated, where such notation is configured in a manner that more closely relates the note to be played with the mechanical action needed to be performed so as to play that note, such as on an instrument to be or being played.
