Lento is the eighth studio album by South Korean jazz singer-songwriter Na Yoon-Sun, released on March 12, 2013 by ACT Music.

In addition, even though she was not originally a jazz musician and had sung various types of music such and rock and classical music, she uses variety of jazz techniques or produces similar effects in her songs in Lento.

In this album, she performs scat singing, creates swing feeling, and the quintet plays in A-A-B-A form in some songs while fusing those techniques with other genres.

One remarkable point other than her vocal jazz performance is her rearrangement of Korean traditional folk song Arirang.

She also received ECHO, the German Grammy as the best international jazz singer and most sold-out album.
