Guitar phím lõm
The đàn lục huyền cầm (chữ Hán: 彈六絃琴) (literally "lute with six strings"), or colloquially đàn ghi-ta phím lõm (literally ghi-ta "guitar," + phím "fret", + lõm "sunken"), is a scalloped Vietnamese adaptation of the French guitar. The guitar, or ghi-ta, was adopted by Vietnamese musicians during the 19th Century.
