Music instrument Kolintang comes from Minahasa, the island of Sulawesi, Eastern Indonesia. The musical percussion instrument is made of light but solid local wood, whose fibrous construction forms parallel lines. The instrument can play both bass and treble tones. The sound comes from the resonance created in the box and requires special precision in sound production. The name "kolintang" comes from the tone: TONG (low pitch note), TING (high pitch note) and TANG (note with moderate pitch). In the local language, the invitation "Let's do some TONG TING TANG" is: "Mangemo kumolintang". In the past, the instrument consisted only of stacked wooden sticks that were placed on the feet of musicians sitting on the floor. Subsequently, the function of the musician's legs as a stand for the instrument was replaced by the banana trunk or a rope that held the wooden board to which the instrument was attached. Kolintang had a close connection with the traditional beliefs of the natives of Minahasa. It was usually played during rituals honoring ancestors. This also explains the reason why the instrument had disappeared. When Christianity entered Minahasa, the kolintang was so rarely played that the instrument was forgotten for about 100 years. It reappeared after World War II, reconstructed to its universal musical scale.
