Abstract
A tone generation apparatus detects a position of a mouthpiece section having been pressed by a human player holding the mouthpiece section in his or her mouth. The tone generation apparatus identifies a tone pitch on the basis of the detected position and human player's operation on a piston control. Also, the tone generation apparatus detects a pressure of breath blown by the human player into the mouthpiece section and generates a tone signal of a wind instrument having the identified tone pitch, and audibly reproduces the tone signal after amplifying the tone signal in accordance with a tone volume level corresponding to the detected pressure of breath.

A tone generation control apparatus for a musical instrument, the tone generation control apparatus comprising:
- a mouthpiece section adapted to be connected to a musical instrument body section of the musical instrument and having a shape suitable for being operated by a mouth of a human player;
- a detector adapted to detect a physical amount caused by operation, by the mouth of the human player, at the mouthpiece section;
- and
- a control section adapted to identify a tone pitch on the basis of the physical amount detected by the detector and generate tone pitch instruction data indicative of the identified tone pitch;
- a control operation unit adapted to be operable by a finger of the human operator;
- and
- an operation detection section adapted to detect an operational state of the control operation unit,
- wherein the control section is further adapted to:
- identify the tone pitch on the basis of a combination of the physical amount detected by the detector and the operational state of the control operation unit detected by the operation detection section;
- generate the tone pitch instruction data indicative of the identified tone pitch;
- identify a harmonic corresponding to the physical amount detected by the detector and the operational state of the control detected by the operation detection section by referencing a tone pitch/harmonic table;
- and
- identify the tone pitch based on the identified harmonic and the operational state of the control operation unit detected by the operation detection section.
An electronic musical instrument comprising:
- a musical instrument body section;
- a mouthpiece section connected to the musical instrument body section and having a shape suitable for being operated by a mouth of a human player;
- a detector adapted to detect a physical amount caused by operation, by the mouth of the human player, at the mouthpiece section;
- a control section adapted to identify a tone pitch on the basis of the physical amount detected by the detector and generate tone pitch instruction data indicative of the identified tone pitch;
- a control operation unit adapted to be operable by a finger of the human operator;
- and
- an operation detection section adapted to detect an operational state of the control operation unit,
- wherein the control section is further adapted to:
- identify the tone pitch on the basis of a combination of the physical amount detected by the detector and the operational state of the control operation unit detected by the operation detection section;
- generate the tone pitch instruction data indicative of the identified tone pitch;
- identify a harmonic corresponding to the physical amount detected by the detector and the operational state of the control detected by the operation detection section by referencing a tone pitch/harmonic table;
- and
- identify the tone pitch based on the identified harmonic and the operational state of the control operation unit detected by the operation detection section.
A tone generation control apparatus for a musical instrument, the tone generation control apparatus comprising:
- a mouthpiece section adapted to be connected to a musical instrument body section of the musical instrument and having a shape suitable for being operated by a mouth of a human player;
- a first detector adapted to detect a first physical amount caused by first operation, by the mouth of the human player, at the mouthpiece section;
- and
- a second detector adapted to detect a second physical amount caused by second operation, by the mouth of the human player, at the mouthpiece section;
- a control section adapted to identify a tone pitch on the basis of the physical amount detected by the first detector and generate tone pitch instruction data indicative of the identified tone pitch,
- wherein the control section generates, in accordance with the second physical amount detected by the second detector, data for controlling a characteristic of a tone to be generated in accordance with the tone pitch instruction data, and
- wherein the second detector detects, as the second physical amount, vibration applied to said mouthpiece section.
