Abstract

A musical performance training system includes a transmitter which transmits training musical note data for training musical performance, and a receiver which receives the training musical note data from the transmitter and instructs a trainee to practice a musical performance based on the received training musical note data. The transmitter produces musical note data based on a musical performance, for example, at a keyboard. The musical note data is converted to training musical note data by reducing velocity data contained in the produced musical note data, shifting pitch data in units of an octave, and changing the timbre and pitch data to respective particular values. If the musical note data is produced by a special key operation, control data which instructs the trainee to perform a pedal operation is added to the converted musical note data. The receiver displays or audibly outputs a performance instruction based on the received training musical note data. And the training musical note data may be transmitted/received via a predetermined storage device on a network.

Claims

1. A performance training data receiver comprising:

receiving means for receiving musical note data sent by an external device;

data detecting means for detecting training musical note data from among the musical note data received by said musical note data receiving means; and

training instructing means for instructing a trainee to practice a musical performance by audibly specifying a key to be depressed based on pitch data contained in the training musical note data.

2. A performance training data receiver comprising:

receiving means for receiving musical note data sent by an external device;

data detecting means for detecting training musical note data from among the musical note data received by said musical note data receiving means; and

training instructing means for instructing a trainee to practice a musical performance by displaying an instruction to urge the trainee to perform a pedal operation based on control data contained in the training musical note data.

3. A recording medium storing a performance training data program for causing a computer to:

receive musical note data sent by an external device;

detect training musical note data from among the received musical note data; and

instruct a trainee to practice a musical performance by audibly specifying a key to be depressed based on pitch data contained in the training musical note data.

4. A recording medium storing a performance training data program for causing a computer to:

receive musical note data sent by an external device;

detect training musical note data from among the received musical note data; and

instruct a trainee to practice a musical performance by displaying an instruction to urge the trainee to perform a pedal operation based on control data contained in the training musical note data.

5. A performance training data transmitter comprising:

musical note producing means for producing musical note data;

data converting means for converting the musical note data into training musical note data by reducing velocity data contained in the musical note data; and

transmitting means for transmitting the training musical note data.

6. A performance training data transmitter comprising:

musical note producing means for producing musical note data;

data converting means for converting the musical note data into training musical note data by shifting pitch data contained in the musical note data; and

transmitting means for transmitting the training musical note data.

7. A performance training data transmitter comprising:

musical note producing means for producing musical note data;

data converting means for converting the musical note data into training musical note data having a predetermined pitch unrelated to pitch data contained in the musical note data and a timbre different from a timbre of the musical note data; and

transmitting means for transmitting the training musical note data.

8. A performance training data transmitter comprising:

musical note data producing means for producing musical note data;

data determining means for determining whether a keyboard performance based on the musical note data involves a special key depression;

control data producing means, responsive to said data determining means determining that the keyboard performance involves the special key depression, for producing control data which instructs a trainee to perform a pedal operation for supplementing the special key depression, and for adding the control data to the musical note data;

data converting means for converting the musical note data to which the control data has been added into training musical note data; and

transmitting means for transmitting the training musical note data.

9. The performance training data transmitter according to claim 8, wherein the special key depression is performed such that there are more than a predetermined number of keys between any particular depressed key and a next depressed key, and wherein the pedal operation is performed to continue musical note production by the particular depressed key.

10. A recording medium storing a performance training data transmitting program for causing a computer to:

produce musical note data;

convert the musical note data into training musical note data by reducing velocity data contained in the musical data; and

transmit the training musical note data.

11. A recording medium storing a performance training data transmitting program for causing a computer to:

produce musical note data;

convert the musical note data into training musical note data by shifting pitch data contained in the musical data; and

transmit the training musical note data.

12. A recording medium storing a performance training data transmitting program for causing a computer to:

produce musical note data;

convert the musical note data into training musical note data having a predetermined pitch unrelated to pitch data contained in the musical note data and a timbre different from a timbre of the musical note data; and

transmit the training musical note data.

13. A recording medium storing a performance training data transmitting program for causing a computer to:

produce musical note data;

determine whether a keyboard performance based on the produced musical note data involves a special key depression;

produce control data which instructs a trainee to perform a pedal operation for supplementing the special key depression when it is determined that the keyboard performance involves the special key depression, and add the control data to the musical note data;

convert the musical note data to which the control data has been added into training musical note data; and

transmit the training musical note data.
