Abstract

In a server apparatus, a storage section stores musical composition data representing a plurality of musical compositions. A transmission section transmits musical composition data which represents a first musical composition to an electronic musical apparatus via a communication network in a streaming manner, such that the electronic musical apparatus can reproduce the first musical composition in realtime basis. A reception section receives operation data from the electronic musical apparatus, the operation data representing a user operation of the electronic musical apparatus performed in response to realtime reproduction of the first musical composition. A control section selects musical composition data representing a second musical composition based on contents of the operation data, such that the second musical composition matches a skill of the user to operate the electronic musical apparatus, and controls the transmission section to transmit the selected musical composition data of the second musical composition to the electronic musical apparatus in-the streaming manner, whereby another user operation can be performed in response to the realtime reproduction of the second musical composition.

Claims

1. A server apparatus for providing musical composition data to an electronic musical apparatus, which is communicably connected to the server apparatus via a communication network, and which is operable by a user, the server apparatus comprising:

a storage section that stores the musical composition data representing a plurality of musical compositions;

a transmission section that transmits musical composition data which is stored in the storage section and which represents a first musical composition, to the electronic musical apparatus via the communication network in a streaming manner, such that the electronic musical apparatus can reproduce the first musical composition in realtime basis according to the transmitted musical composition data;

a reception section that receives operation data from the electronic musical apparatus via the communication network, the operation data representing a user operation of the electronic musical apparatus performed in response to realtime reproduction of the first musical composition; and

a control section that selects musical composition data representing a second musical composition from the storage section based on contents of the operation data received by the reception section, such that the second musical composition matches a skill of the user to operate the electronic musical apparatus, and that controls the transmission section to transmit the selected musical composition data of the second musical composition to the electronic musical apparatus in the streaming manner, whereby another user operation can be performed in response to the realtime reproduction of the second musical composition.

2. The server apparatus according to claim 1, wherein the transmission section transmits the musical composition data in the streaming manner together with control data which controls the electronic musical apparatus to store the transmitted musical composition data in a temporary memory of the electronic musical apparatus for the realtime reproduction of the musical composition, and which controls the electronic musical apparatus to delete the musical composition data from the temporary memory when the realtime reproduction of the musical composition terminates.

3. The server apparatus according to claim 1, wherein the control section selects the musical composition data representing a multiple of second musical compositions from the storage section based on contents of the operation data received by the reception section, and controls the transmission section to transmit a list of the multiple of the second musical compositions to the electronic musical apparatus for allowing the user to select a desired one of the second musical compositions.

4. The server apparatus according to claim 1, wherein the control section compares the contents of the operation data with the musical composition data of the first musical composition so as to evaluate the skill of the user to operate the electronic musical apparatus.

5. A method of providing musical composition data to an electronic musical apparatus, which is communicably connected to the server apparatus via a communication network, and which is operable by a user, the method comprising the steps of:

storing the musical composition data representing a plurality of musical compositions;

transmitting musical composition data which represents a first musical composition to the electronic musical apparatus via the communication network in a streaming manner, such that the electronic musical apparatus can reproduce the first musical composition in realtime basis according to the transmitted musical composition data;

receiving operation data from the electronic musical apparatus via the communication network, the operation data representing a user operation of the electronic musical apparatus performed in response to realtime reproduction of the first musical composition;

selecting musical composition data representing a second musical composition based on contents of the operation data, such that the second musical composition matches a skill of the user to operate the electronic musical apparatus; and

transmitting the selected musical composition data of the second musical composition to the electronic musical apparatus in the streaming manner, whereby another user operation can be performed in response to the realtime reproduction of the second musical composition.

6. An electronic musical apparatus operable by a user for using musical composition data provided from a server apparatus communicably connected to the electronic musical apparatus via a communication network, the electronic musical apparatus comprising:

a reception section that receives the musical composition data from the server apparatus in a streaming manner via the communication network;

a storage section that temporarily stores the musical composition data received by the reception section;

a reproduction section that reproduces the musical composition data temporarily stored in the storage section in realtime basis;

a detection section that detects a user operation of the electronic musical apparatus performed in response to realtime reproduction of the musical composition data by the reproduction section;

a transmission section that transmits operation data representing the user operation detected by the detection section to the server apparatus via the communication network; and

a deletion section that deletes the musical composition data from the storage section when the realtime reproduction of the musical composition data terminates.
