Sonja writes and plays music as a positive outlet for her emotions. She started her YouTube channel in 2018, uploading original songs as well as pop/rock cover songs. In 2019, she successfully participated in the competition "Jugend musiziert" in the category pop vocals. As part of a band or as a solo artist, she has been playing concerts regularly for a few years. She has been the singer of the Irish folk band "Mad for Tunes" from 2018 to 2020 and is currently engaged in the alternative rock band "Wake Up Sophie" (vocals, piano, ukulele). In 2020, the singer-songwriter from Mönkeberg, Germany released her first EP “Ways”. Two songs thereof had their Scottish radio debut in March 2021. “Ways” is a collection of ballads about themes connected to mental health and finding one’s way in life. “Fight Back” (2023) continues to process challenging life situations, as it explores feelings resulting from sexualised violence, aiming to raise awareness and spend comfort to those affected. "Hanna's Song" (2024) showcases a wider range of instrumental abilities and explores a happy mood associated with friendship. After completing a bachelor’s degree in social work, Sonja pursues a master’s in music therapy to combine her passion for music and musical skills with her aspiration to support other people’s well-being.
