The problem of time lag is critical in music ensemble. Several researches are reported to support ensemble under time lag by use special protocol or special music score. However these methods are not able to extend to more general ensemble. So in this research, we analyzed the affection of time lag on music ensemble. Under the condition of smaller time lag (less than 50ms), the ensemble was similar to the condition of no time lag. However, while time lag increased, one side of performer precedes the other side of performer, and finally the ensemble fails in the larger time lag (greater than 80ms). Therefore, the prediction of performance is necessary to perform the ensemble, and analysis of these mechanisms would be effective to construct the ensemble support system.
