As a songwriter, Parvyn explores themes of perception and reality, love and family. Throughout Sa she explicitly reflects on her own struggles with mental health issues, growing up in Australia with immigrant parents and navigating having a young family of her own. Parvyn sings in both Punjabi and English and her range as a singer is almost impossibly broad. She easily swings from deftly executing virtuosic Indian classical ideas to delivering disarmingly personal lyrics to ethereal improvisations and tonal landscapes. The voice and the songwriting are the threads that bind this diverse record together.
