摘要： Play pistons 11 to 13 are incorporated in a trumpet-shaped housing 10 at the upper central part in the front-and-back direction. An air vibration sensor 24 for inputting voices is provided at the end surface on the front side of housing 10. When a player inputs voices into air vibration sensor 24 simultaneously with the player's operation of play pistons 11 to 13, a musical tone is generated having a tone pitch that is determined by a combination of the operation of play pistons 11 to 13 and the frequency of the voice sound signal. Rings 17 to 19 formed of transparent or translucent resin and emitting light by energization of light-emitting elements 21 to 23 are incorporated at the foot of play pistons 11 to 13. Through energization of light-emitting elements 21 to 23 in accordance with performance data, light emission of rings 17 to 19 guides playing. Thus, the player can easily play and practice on a musical instrument, such as a trumpet, that determines the tone pitch of a musical tone in accordance with a combination of operation of a plurality of play operators.

摘要： There is provided a keyboard apparatus which has a high durability, portability, and operability, and facilitates adaptation to a wide range of musical scenes and to multi-model production. Each adjacent pair of four main cases are pivotally connected to each other via connecting portions, whereby the main cases are allowed to assume a folded position which enables the keyboard apparatus to be carried with ease, and a flat unfolded position in which the keyboard can be played. Each main case has a keyboard unit arranged therein. Three main cases for lower tone ranges each have four white keys arranged therein, and a main case for a highest tone range has three white keys arranged therein, and a total of 25 keys are arranged on the keyboard apparatus. The main case for the highest tone range also has a group of operating elements arranged therein.
