Abstract
While a player is fingering a music tune on a piano, an electronic assistant system monitors the keys to see whether or not the player starts to produce tones through a particular playing technique such as repetition; when the electronic assistant system finds particular key movements unique to the particular playing technique in an early stage, the electronic assistant system decides that the player intends to produce the tone through the particular playing technique, and forces the key to travel on a reference key trajectory in the later stage, whereby the player learns the particular playing technique.
Claims18
An electronic assistant system for a player, comprising:
- a sensor system monitoring manipulators of a musical instrument, and producing detecting signals representative of pieces of performance data expressing movements of said manipulators;
- actuators provided in association with said manipulators, and responsive to a driving signal so as to move said manipulators;
- an analyzer connected to said sensor system, and analyzing said pieces of performance data to see whether or not at least one of said manipulators takes a particular movement indicative of player's intention to produce music sound through a particular playing technique during fingering of a human player on said manipulators;
- and
- a driver connected to said actuators and said analyzer, and supplying said driving signal to associated one of said actuators so as to give rise to a movement of said one of said manipulators featuring said particular playing technique in said fingering when said analyzer gives the answer affirmative for assisting said human player in learning said particular playing technique,
- wherein said analyzer searches said pieces of performance data for a piece of performance data expressing a stoppage for a certain time period between a rest position of the manipulator and an end position of said manipulator.
A musical instrument on which a player performs pieces of music, comprising:
- manipulators manipulated by said player for said pieces of music;
- a tone generator connected to said manipulators, and responsive to the manipulation on said manipulators so as to produce music sound for said pieces of music;
- an electronic assistant system provided in association with said manipulators, and including
- a sensor system monitoring said manipulators and producing detecting signals representative of pieces of performance data expressing movements of said manipulators,
- actuators provided in association with said manipulators and responsive to a driving signal so as to move said manipulators,
- an analyzer connected to said sensor system and analyzing said pieces of performance data to see whether or not at least one of said manipulators takes a particular movement indicative of player's intention to produce the music sound through a particular playing technique during fingering of a human player on said manipulators and
- a driver connected to said actuators and said analyzer and supplying said driving signal to associated one of said actuators so as to give rise to a movement of said one of said manipulators featuring said particular playing technique in said fingering when said analyzer gives the answer affirmative for assisting said human player in learning said particular playing technique,
- wherein said analyzer searches said pieces of performance data for a piece of performance data expressing a stoppage for a certain time period at an intermediate position between a rest position of the manipulator and an end position of said manipulator.
