Performance interface system includes a motion detector provided for movement with a performer, and a control system for receiving detection data transmitted from the motion detector and controlling a performance of a tone in response to the received detection data. State of a performer's motion is detected via a sensor of the motion detector, and detection data representative of the detected motion state is transmitted to the control system. The control system receives the detection data from the motion detector, analyzes the performer's motion on the basis of the detection data, and then controls a tone performance in accordance with the analyzed data. With this arrangement, the performer can readily take part in the tone performance in the control system. For example, as the performer moves his or her hand, leg or trunk while listening to a manual or automatic performance of a music piece being carried out by a performance apparatus of the control system, the motion detector detects the performer's motion and transmits corresponding detection data to the control system, which in turn variably controls a predetermined one of tonal factors in the music piece performance. This arrangement can readily provide interactive performance control and thereby allows an inexperienced or unskilled performer to take part in a performance with enjoyment.

Apparatus and method for detecting performer's motion to interactively control performance of music or the like

An ensemble system enabling easy, flexible assignment of performance parts to the facilitator and the performers. In 'setting' field, performance terminals (facilitator and piano (to)) are displayed. A pull-down menu for selecting presence/absence of each performance terminal and radio buttons for assigning performance parts are displayed. According to the presence/absence of each student, the selection of a presence/absence menu is inputted. When song title data is selected, a controller () reads a part assignment table of the song data and assigns a performance part to each performance terminal for which presence is selected. A performance part can be manually assigned to each performance terminal.

Ensemble system

An electronic musical instrument is provided, which makes it possible to manage a state of attendance (presence/absence, etc.) of participants and perform easy management on the level of activity on a daily, weekly, or monthly basis. According to performance operations on performance terminals, a controllerrecords a performance history. Performance terminalsto which performance parts have been assigned by a Facilitator are determined as being present, whereas performance terminalto which no performance parts have been assigned are determined as being absent. The number of times of key depression on each performance terminal, the average key depression intensity (average Velocity), etc. from start to end of a performance are recorded. The recorded values for respective items are output in the form of text data. Since values for the respective item are recorded at every performance, the frequency of attendance of respective users can easily be managed on a daily, weekly, or monthly basis.

An ensemble system enabling even performer unskilled in playing a musical instrument to easily grasp the difference in tempo from the performance of the facilitator. The circle corresponding to the performance terminal 'Facilitator' is indicated fixedly on the center line of the vertical lines. The circle corresponding to the performance terminal (for example, piano ()) of each user moves horizontally correspondingly to the difference from the performance terminal 'Facilitator'. If the press of a key of performance terminal lags behind that of the performance terminal &#x201c;Facilitator&#x201d; by one bar, the circle moves left onto the vertical line next to the vertical center line. If the press of a key of the performance terminal lags behind that of the performance terminal &#x201c;Facilitator&#x201d; by half the bar (two beats), the circle moves left by half the interval between the vertical lines from the vertical center line. If the press of a key of the performance terminal leads that of the performance terminal &#x201c;Facilitator&#x201d;, the circle moves right (FIG.).
