The proper distance between the string of erhu and the pole of the instrument is the essential condition for the player to keep the correct hand shape.Because the distance from the left side of the pole to the terminal surface of the musical instrument tube in the structure is certain,the juvenile players or the players with smaller fingers have to adjust QianJin short,make the string thread overly slope.According to the erhu playing method and vibration characteristics and through the analysis,it points out this causes the amplitude of the string and instrument leather diminished theoretically,making volume lower and difficult to play the figure of power change consequently;At the same time it is difficult to realize the way of rub pressing of string in roll and press combination.Suggestions has proposed for mannfacturing the instrument.
