An electronic musical instrument includes: a plurality of performance elements that specify pitch data; a sound source that produces musical sounds; and a processor configured to perform the following: when a user performance of the plurality of performance elements satisfies a prescribed condition, instructing the sound source to produce a sound of a first timbre and a sound of a second timbre, both corresponding to a pitch data specified by the user performance; and when the user performance of the plurality of performance elements does not satisfy the prescribed condition, instructing the sound source to produce the sound of the first timbre corresponding to the pitch data specified by the user performance and not instructing the sound source to produce the sound of the second timbre.

Systems and methods for mapping parts in a digital sheet music file for a harmony. The method may include receiving a selection of a music segment for part mapping, receiving a digital sheet music representation of the selected music segment, and determining a plurality of plausible part mapping for the digital sheet music representation. A part mapping identifies one or more distinct musical parts in the digital sheet music representation, each of said one or more distinct musical parts corresponding to a performer of the harmony. The method may also include analyzing one or more features of the plurality of plausible part mapping to identify a highest probability part mapping based on previously stored information, and outputting the highest probability part mapping.

There is provided an information processing device, an information processing method, and a program that can provide an information processing device, an information processing method, and a program that can effectively assist in learning performance. The information processing device includes a sensing data obtaining section configured to obtain sensing data regarding at least one of a motion pattern, a motion speed, a motion accuracy, and a motion amount of a motion element of a user in a practice in performance performed by movement of at least a part of a body of the user and a state of a result produced by the performance, an analyzing section configured to analyze the obtained sensing data and estimate information regarding the practice in the performance of the user on a basis of a result of the analysis, and an output section configured to output a result of the estimation to the user.

In some embodiments, a method of combining two or more songs to present one or more campaigns to a plurality of audience members is provided. The method can include combining a first music selection, a second music selection, and one or more videos into a campaign video. The method can further comprise providing the campaign video for playback to the plurality of audience members and receiving a vote from the plurality of audience members, the vote reflecting a preference for the first selection or the second selection.

A method of distribution of digital musical scores for performance by a plurality of musicians. The method includes: receiving a musical score request from a user device; obtaining, via a musical score source, a set of musical score components of a musical part for a piece of music associated with the musical score request; obtaining a transmission delay value associated with a communication path; providing, from the musical score source and using the processor, at least one of the set of musical score components to the user device using a first distribution timing based on the obtained transmission delay value; and providing a set of corresponding musical score components of a different musical part for the piece of music to a different user device based on a different transmission delay value associated with the different user device, such as to enable coordinated playback by users without a conductor.

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for training a musical work adaptation quality evaluation model. One of the methods includes: obtaining a plurality of adapted musical work samples; separating audio tracks of each of the plurality of adapted musical work samples; determining instrument information identifying instruments played in each of the audio tracks; performing originality analysis on each of the audio tracks to obtain an originality value corresponding to each audio track; for each of the audio tracks, using a combination of the instrument information and the originality value corresponding to the particular audio track of the adapted musical work samples as a sample feature; and training a musical work adaptation quality evaluation model by using sample features of corresponding adapted musical work samples as input, and a predetermined evaluation score of the corresponding adapted musical work sample as output.

Aspects of embodiments pertain to a method for determining an Input/Output (I/O) device configuration for a music teaching system. The method may comprise receiving a plurality of I/O device configurations of a music teaching system; receiving, for a given I/O device of the music teaching system, an initial I/O device configuration; and determining an updated I/O device configuration for the given I/O Device, based on the initial I/O device configuration of the given I/O Device and at least one of the plurality of received I/O device configurations. The determining is performed such that the updated I/O device configuration has improved device performance compared to the initial I/O device configuration.

An apparatus, method, and computer-readable storage medium that generate at least a cue point in a musical piece. The method includes generating a beat grid representing the musical piece, determining values for the beat grid, the values corresponding to an audio feature of the musical piece, and each value representing an entire duration of each beat in the beat grid of the musical piece, calculating a score for the audio feature at each of a plurality of positions in the beat grid of the musical piece, using some or all of the determined values, and generating the cue point at a particular position of the plurality of positions, based on the calculated scores.

A method for online music learning of playing a musical instrument, that may be a string instrument, a woodwind instrument, a brass instrument, a percussion instrument, or vocal (singing) is described. A client device, such as a smartphone or a tablet notifies a person, such as visually by a display or audibly by a sounder, of a sequence of musical symbols that may be part of a musical piece to be played on the musical instrument. The pace or tempo of the notified sequence is adapted according to a stored skill level value of the person and the pace or tempo associated with the musical piece. The client device, monitors, using a microphone(s) in the client device, the errors in the playing of the sequence, and using a predefined accordingly updates the stored skill level value, and accordingly changes the arrangement, pace and/or tempo of the next sequence of musical symbols.
