A keyboard apparatus according to an embodiment includes a keyboard and a mutual capacitance proximity sensor. The keyboard includes a first key and a second key arranged in an array direction with respect to the first key. The proximity sensor includes a first electrode having a portion extending from at least a first area below the first key to a second area below the second key, a second electrode arranged in the first area, and a third electrode arranged in the second area. The proximity sensor is a mutual capacitance type sensor and is configured to use a change in capacitance between the first electrode and the second electrode and a change in capacitance between the first electrode and the third electrode.

Keyboard apparatus and proximity sensor

The information providing method includes: sequentially identifying a performance speed at which a user performs a piece of music; identifying, in the piece of music, a performance position that is performed by the user; setting an adjustment amount in accordance with a temporal variation in the identified performance speed; and providing the user with music information corresponding to a time point that is later, by the adjustment amount, than a time point that corresponds to the performance position identified in the piece of music.

Information providing method and information providing device

A chord detection apparatus retrieves musical performance data indicative of musical performance played by a user, retrieves musical piece information indicative of a musical piece played by the user, retrieves chord tendency information indicative of degrees of likelihood or unlikelihood of chords appearing in the musical piece, and detects a chord on the basis of the retrieved musical performance data and the retrieved chord tendency information.

Apparatus and method for detecting chord

An electronic musical instrument and a portable terminal are connected to a wireless LAN. The wireless LAN is connected to an Internet via a router. A distribution server residing on the Internet is a server which provides Internet services. A pairing between the electronic musical instrument and the portable terminal is established to conduct Internet communications in a pair. Processes from accessing the distribution server to specifying a desired service are performed by use of the portable terminal. The distribution server distributes data corresponding to the service specified by the portable terminal to the electronic musical instrument. A user is thus allowed to use the desired service on the electronic musical instrument. ,

Service provision system for electronic musical apparatus

In an electronic musical instrument, an interface part obtains user information from a dedicated accessory device logically connected to the electronic musical instrument. An access part accesses a server using the user information obtained through the interface part. A character information acquisition part obtains character information which represents a character and which corresponds to the user information, from the server or the dedicated accessory device. A lesson information acquisition part obtains, from the server, lesson information which represents a lesson work to be practiced. A control part performs control operation to display the character created based on the character information obtained by the character information acquisition part while the electronic musical instrument is logically connected to the dedicated accessory device through the interface part, and to display the lesson information when the lesson information has been obtained by the lesson information acquisition part.

Accessory device, electronic musical instrument and teaching apparatus

A musical interaction assisting apparatus is to enhance friendliness between an electronic musical instrument and the player. The player's actions are detected acoustically, visually or physically, and the interaction assisting apparatus interprets the detected player's actions and generates interactive responses thereto. The interactive responses are outputted acoustically, visually or physically for the player, and electronically to control the electronic musical instrument. The interaction assisting apparatus also has a learning function to provide proper responses to the player.

Musical interaction assisting apparatus

As a player inputs a performance of a music piece by playing a musical instrument or singing a song, an add-on apparatus automatically starts an add-on progression such as an accompaniment to the music piece, a score and word display of the music piece and a picture display for the music piece. The apparatus stores a plurality of accompaniment or score-and-word or picture data files each corresponding to each of a plurality of music pieces. The apparatus recognizes the music piece under the performance inputted by the player, selects the accompaniment or score-and-word or picture date file which corresponds to the recognized music piece, and causes the accompaniment progression or score-and-word display or picture display to start automatically and run along with the progression of the music piece automatically.

Apparatus for automatically starting add-on progression to run with inputted music, and computer program therefor

A connection setting apparatus having a connection information acquiring unit for acquiring first connection information from a plurality of apparatus connected to a network, each apparatus having at least one line, and a generating unit for generating second connection information in accordance with the acquired first connection information.

Connection setting apparatus

A communication control apparatus is provided for setting a plurality of node apparatuses to either of a transmitter and a receiver of synchronization information to synchronize the node apparatuses with each other. A storage device memorizes capability information representing either of an active capability to transmit the synchronization information and a passive capability to receive the synchronization information, owned by each of the node apparatuses. An indicating device indicates the active capabilities and the passive capabilities owned by the node apparatuses. A specifying device is operated in association with the indicated active capabilities and the passive capabilities for outputting status information effective to specify each node apparatus to a transmitter or a receiver. A plurality of memory blocks are provided in correspondence to the plurality of the node apparatuses to memorize status information. A registering device registers each of the outputted status information into each memory block to set the corresponding node apparatus to a transmitter of the synchronization information when the status information specifies the transmitter, and to set the corresponding node apparatus to a receiver of the synchronization information when the status information specifies the receiver.
