A piano system is provided. A system including a keyboard including a plurality of keys; a plurality of sensors connected to the plurality of keys; a screen; at least one processor, and a non-transitory computer readable medium comprising instructions, the instructions, when executed by the at least one processor, causing the system to effectuate a method comprising: dividing the plurality of sensors into a first group and a second group; receiving a first sensor signal from the first group and a second sensor signal from the second group; generating a first parameter for the first group and a second parameter for the second group; generating a first sound control signal for the first group and a second sound control signal for the second group; generating visual information related to the first and the second sensor signal; and displaying the visual information on the screen.

A video game includes an audio-video stream combined with game graphics and game sounds. The game graphics are overlaid on the video stream and updated in synchronization with the stream. Update of the game graphics and sounds depends on inputs received from a game player. The game player may provide input using a game controller coupled to the video game by an adapter. The video game may play on a Blu-ray player.

An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

The intelligent accompaniment generating system includes an input module, an analysis module, a generation module and a musical equipment. The input module is configured to receive a musical pattern signal derived from a raw signal. The analysis module is configured to analyze the musical pattern signal to extract a set of audio features, wherein the input module is configured to transmit the musical pattern signal to the analysis module. The generation module is configured to obtain a playing assistance information having an accompaniment pattern from the analysis module, wherein the accompaniment pattern has at least two parts having different onsets therebetween, and each onsets of the at least two parts is generated by an algorithm according to the set of audio features. The musical equipment includes a digital amplifier configured to output an accompaniment signal according to the accompaniment pattern.

A frequency detection and display device includes a body having a vibratory portion configured for vibrating at a predetermined frequency. In this manner, the vibratory portion provides a visible indication corresponding to the predetermined frequency in response to vibration of an object, such as a stringed musical instrument, to which the frequency detection and display device is attached.

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.

A switch device (4, 5) includes: a cap (7) including, on a top surface (711), a first region (71a) and a second region (71b) corresponding to a position where an internal light (133) is disposed and being thinner than the first region (71a); and a switch (61, 62) to which the cap (7) is mounted.

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.

Playback, recording, and analysis of music scales via software configuration. In an embodiment, a graphical user interface is generated with staff and keyboard canvases, visually representing a music staff and keyboard, respectively, a scale input, parameter input(s), and a play input. In response to selection of a scale, the staff canvas is updated to visually represent the notes in the scale. In response to the selection of a musical parameter, the staff canvas and/or keyboard canvas are updated to reflect the musical parameter. In response to selection of the play input, a soundtrack of the scale is output, while simultaneously highlighting the note, being played, on the staff canvas and the key, associated with the note being played, on the keyboard canvas.
