Sound is created by the vibration of strings. Musicians play these by plucking, bowing, or occasionally striking the strings.

Examples: Violin, viola, cello, double bass, and harp.

1. Double bass (ដាប់បលបាស): E, A, D, G
2. Viola (វីយូឡា): C, G, D, A
3. Cello (សែលឡូ): C, G, D, A
4. វីយូឡុង (Violin): G, D, A, E
5. Harp (ហាប): Red strings are C notes, and blue or black strings are F notes, acting like piano's white keys, with white strings filling in the D, E, G, A, B notes in sequence as you go up the harp.
6. Guitar (ហ្គីតា): E, A, D, G, B, E
