CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to Chinese Patent Application No. 201911400474.4 with a filing date of Dec. 23, 2019. The content of the aforementioned application, including any intervening amendments thereto, are incorporated herein by reference. 
     TECHNICAL FIELD 
     The invention relates to the technical field of musical instrument equipment, in particular to a band ensemble instrument. 
     BACKGROUND ART 
     The existing digital pianos usually make monotonous sounds. Some electric pianos with high price not only can provide the piano timbre in a professional performance, but also are provided with wind music, string music and other multiple timbres. The overlapping function can play two timbres at the same time, and the dividing function can divide the keyboard into two parts to play two different timbres respectively, but cannot overlap more than three different timbre combination performances. The solo and ensemble functions cannot be realized in the process of overlapping multiple timbres, so that effects of one band cannot be achieved in playing. Not only in entertainment, but also in a performance, an electric piano produces thin and monotonous sounds, lacks rich and thick sound production effects, is bulky and heavy in size, and is extremely inconvenient to move. Therefore, the invention aims to provide an ensemble instrument which is convenient to use and can be overlapped and combined by a plurality of musical instruments. The invention not only can play the piano, but also can play the traditional opera and national music, as well as achieve the overlapped and combined playing of western musical instruments. It has small size, low cost, and can get the band sound effects with itself, which is portable and practical.
