Abstract

There is provided a musical tone control apparatus that enables a user to easily play a musical instrument without spoiling the user'"'"'s feeling that he is actually playing a musical instrument. A storage device stores musical piece data containing interval data indicative of intervals of musical tones constituting a musical piece. A motion of an operator is detected. A controller provides control so as to instruct a musical tone output device capable of outputting musical tones to adopt the intervals as one of characteristic amounts relating to musical tones to be output from the musical tone output device, according to the interval data, and instruct the musical tone output device to adopt at least one of the characteristic amounts other than the intervals according to the detected motion of the operator.

Claims

1. A musical tone control apparatus comprising:

a storage device that stores musical piece data containing interval data indicative of intervals of musical tones constituting a musical piece;

an extended string;

a detecting device that detects vibration imparted to said string; and

a controller that provides control so as to output, to a musical tone output device capable of outputting musical tones of intervals according to interval data inputted, said interval data stored in said storage device in a case where said detecting device detects said vibration being imparted to said string, and instruct the musical tone output device to stop outputting the musical tones in a case where said detecting device detects a magnitude of said vibration of said string being less than a predetermined value, wherein the musical tone output device starts outputting musical tones of said intervals according to said interval data when said interval data is inputted, continues to output said musical tones during a time period after starting outputting said musical tones before receiving said instruction of stopping said musical tones, and stops outputting said musical tones when receiving said instruction of stopping said musical tones.

2. A musical tone control apparatus according to claim 1, wherein said controller provides control so as to read out and then output said interval data stored in said storage device, according to a predetermined tempo, during a time period after said detecting device detects said vibration being imparted to said string before said detecting device defects said magnitude of said vibration of said string being less than the predetermined value, and to stop outputting said interval data in a case said detecting device detects said magnitude of said vibration of said string being less than a predetermined value.

3. A musical tone control apparatus according to claim 1, wherein said detecting device further detects a tilt of said musical tone control apparatus, and said controller provides control so as to instruct the musical tone output device to adopt a volume corresponding to the tilt of the musical tone control apparatus, as a volume with which the, musical tones to be output from the musical tone output device.

4. A musical tone control apparatus according to claim 1, wherein said musical tone control apparatus has the musical tone output device in one body therewith.
