Shelly Quarmby is a singer-songwriter whose music blends country, pop and rock, with piano-led arrangements and personal lyrics. Her sound is compared with artists such as Sarah McLachlan, Natalie Maines, Paula Cole, Chantal Kreviazuk, Jewel and Vonda Shepard.

Her writing is shaped by songwriters including Jimmy Webb, Randy Newman, Carole King and Beth Nielsen Chapman. She performs with vocals and keyboard, and her songs are described as emotionally direct and strongly rooted in piano-driven hooks.

Live descriptions emphasise her country-tinged vocals and keyboard playing, and her work is associated with an EP that has been described in press as having moments of heart-stopping magic. The material is presented as autobiographical in tone and built around simple, effective piano-led country-pop.
