The use of the hand sign method is often used in playing diatonic angklung. The Hand sign method was popularized by Zoltan Kodaly in the mid-20th century. The method consists of eight forms of hand sign symbols. Each type of symbol is visually linked to a note on the Major scale. The demonstration is done through the instructor's/trainer's right hand, so that when the instructor demonstrates the hand sign symbol, the movement will become a series of notes or melodies. This paper aims to understand how the application of the Hand sign method Kodaly in an interactive angklung diatonic ensemble show. It also designed the design of the left hand symbol for chord purposes.
