10cm is named for the height difference between the group's two members, and this sense of humour carries over to the music, with a cheeky approach to topics like sex and romance that complements the duo's jaunty sound. They're a classic example of Korean “coffee shop” indie: sweet folk-pop songs anchored by acoustic guitar or piano chords, filled out with instruments like melodion and djembe, and carried by singer Kwon Jeong Yeol's warm, distinct voice.
