Janina Fink was born in Lucerne and showed her talent for the violin at the age of three. She began playing the violin at an early age using the Suzuki method and soon developed a passion for a diverse repertoire. In 2014, she began studying for a Bachelor of Arts in Music with a focus on classical music and regularly attended workshops and master classes with well-known violinists such as Ivan Straus, Yair Kless, Detlef Hahn, Hansheinz Schneeberger, Aylen Pritchin, Valeriy Sokolov and Oriol Sana. In 2019 she completed her master's degree in instrumental pedagogy with a focus on classical music at the Lucerne University of Music with Professor Igor Karsko.

In her master's thesis, Janina Fink dealt with the topic of "Mental training with children in music lessons", which shows her deep connection to the educational side of music. She is currently continuing her education and completing her second master's degree in jazz performance and a minor in folk music at the Lucerne University of Applied Sciences - music with Simon Heggendorn, Roland von Flüe, Roberto Bossard and Nils Wogram.

Janina Fink's musical activities are extremely diverse and range from small band performances to specially organized concerts to orchestral performances on an international level. She performs an average of around 60 performances per year. Janina is a member and occasional guest musician in various regionally and nationally known orchestras such as the Ars Excelsis Ensemble and the 21st Century Orchestra. With her duo JÄÄS, which she founded herself, she regularly performs at various events and develops her own musical language.

Another important project by Janina Fink is NEW BALKAN FOLK. Here she explores traditional folk music from the Balkans and jazz influences in an experimental way, creating a new interpretation of this style of music.

In addition to her artistic work, Janina is also active as a teacher. She leads the folk music ensemble at the Zug Music School and teaches as a violin teacher at the St. Fidelis College in Stans NW and at the Buochs NW Music School. With her passion and talent, she inspires the next generation of musicians and actively contributes to musical education.
