Keyboard apparatus

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

Musical instrument

An electronic musical apparatus assists a performance based on music performance data of a model music piece composed of a plurality of notes allocated to a plurality of channels. Each note is determined by a target pitch and timing. An indicator section visually indicates the target timings of the notes. An input section is operable by a user for sequentially inputting actual timings selectively allocated to one or more of the channels during the performance. A detecting section operates when the input section inputs an actual timing to one channel, for detecting a note having a target timing which matches the inputted actual timing and which is allocated to any one of the channels. An output section responds to the detecting section for outputting the music performance data to the respective channels for sounding all of the notes having the target timings coincident with the inputting of the actual timing.

Electronic musical instrument with performance assistance function

In response to user's selection of a desired instrument style such as a piano style, only some of memory-stored automatic performance data sets that belong to the selected instrument style are made selectable. On the other hand, a tonal characteristic for manual performance is set to a tonal characteristic corresponding to the selected instrument switch. Thus, in executing an ensemble of manual and automatic performances, even a beginner can readily select and set a tone color and performance pattern. According to another aspect, there is provided a memory storing a plurality of automatic performance data sets and the setting parameters in corresponding relation to a plurality of performance styles. Tone setting parameters include manual performance tone setting parameters that are suited at least for the plurality of performance styles. Thus, once a performance style is selected for a desired automatic performance, not only the automatic performance data set but also the manual performance tone setting parameters suited for the performance style can be automatically selectively read out from the memory, and a tone based on a manual performance via a keyboard or the like is set in accordance with the manual performance tone setting parameters.

An electronic musical apparatus for effectively displaying musical information such as notes and beats is configured using a keyboard, a visual display (e.g., liquid crystal display) and a storage device. A keyboard pattern, a bass staff and a treble staff are displayed on a screen of the visual display. Herein, the keyboard pattern is displayed at a lower base area of the screen while the bass staff is displayed at a lower left area of the screen, and the treble staff is displayed at an upper right area of the screen. In addition, a right end of the bass staff and a left end of the treble staff are located approximately in proximity to a center of the keyboard pattern which corresponds to a key of middle C note in a horizontal direction on the screen. Based on performance data stored in the storage device, keys of the keyboard pattern are respectively displayed to show a progression of notes of a tune. The notes of the tune are sequentially displayed on the bass staff and treble staff, wherein the notes are displayed in accordance with note display positions which are disposed in a direction from the lower left to the upper right on the screen. Further, timings of beats of the tune are displayed using images of hands which are displayed at a predetermined area on the screen. For example, the electronic musical apparatus displays an image of clapping hands and an image of opening hands alternatively.
