The đàn tranh is a traditional Vietnamese zither with a long, slender body and multiple strings, typically ranging from 16 to 21. It produces a delicate, melodic sound that is both gentle and expressive, often used in folk music, classical performances, and modern compositions. The strings are plucked with the fingers or small picks, allowing for intricate melodies, harmonics, and glissandos. The đàn tranh is cherished for its ability to convey deep emotion and create a serene, soothing atmosphere, making it an iconic instrument in Vietnamese culture.
