Purchased near Bangkok, Thailand, 1963
From Graciela's Notes
The angklung is a sliding rattle. Two or more bamboo tubes hang loosely within a frame and make a sound when shaken sideways. An angklung plays notes of one pitch, with each of the tubes tuned in octaves. My angklung has three bamboo tubes so it plays in tones in three octaves. In the popular angklung ensembles found in Thailand and Indonesia you often have three or more angklungs play melodies together. And that it is quite exciting and interesting. The frame is made of wood. I purchased the angklung at a small village not far from Bangkok where we had gone to spend the day and watch folk dances. The angklung was one of the folk instruments used during the folk dancing presentation. I bought it in December 1963.
