The flautist Ágnes Vass grew up in Szentgotthárd, Hungary and received her first music lessons in kindergarten. At the age of 14 she began to study at the Conservatory in Szombathely as a pre-tertiary student. There she received lessons from Andrea Bertalan, flautist of the early music ensemble Capella Savaria. The spirited and true-to-style music-making of this ensemble has had a very strong impact on the young musician.

After graduating from high school Ágnes moved to Switzerland to further her studies. She studied with Prof. Christian Studler for three years at the Bern University of the Arts. This was followed by another four years of studies at the Zurich University of the Arts with Prof. Philippe Racine and Sabine Poyé-Morel. She completed both the Master of Performance and Master of Education degrees with the highest grades and distinction.

Ágnes Vass participated masterclasses by Emily Beynon, Andrea Lieberknecht and Michael Kofler. 

She has won numerous competitions and grants, including 1st prize at the international competition I Solisti del Vento in Belgium, 2nd prize at the Swiss Association of Music Competition, 1st prize at the Zurich Marguerite Meisters Competition, the Yehudi Menuhin Foundation Live Music Now, LYRA Prize for young talents and the Fritz Gerber Foundation for talented young people .

With the CODA Wind Quintet, of which she was a member for three years, Ágnes Vass won first prize at the competition for contemporary music in Zurich .

She was a member of the Youth Symphony Orchestra of the Animato Foundation, Valiant Youth Orchestra and the Verbier Festival Orchestra, under the direction of Charles Dutoit and Valery Gergiev. During her studies, she completed a one-year internship at the Biel-Solothurn Theater Orchestra and worked regularly with the Swedish National Orchestra in Gothenburg for eighteen months. Ágnes Vass played as a guest player in the Symphony Orchestra of Bern, Kammerorchester Basel and the Kammerphilharmonie Graubünden. This was followed by solo engagements at the DAVOS Festival and temporary contracts with the Bremen Philharmonic and the Tonhalle Orchestra Zurich. As an orchestral musician, Ágnes Vass has worked with the most renowned conductors such as Sir Simon Rattle, Christoph Eschenbach, Paavo Järvi, Kent Nagano, Daniel Harding, Antonio Pappano, Iván Fischer, Gábor Takács-Nagy, Jakob Hrůša, Jesús López Cobos, and Michael Tilson Thomas.

Ágnes Vass has always been a very versatile, creative musician. Exploration of unusual performance formats is a part of her musical life, such as improvisation with live electronics, guest performances at Ensemble Proton Bern and collaboration with composers. She performed the solo piece "Cadenza" by Péter Eötvös in the small hall of Tonhalle Zurich after working directly with the composer. A particularly fond memory for her is the Kurtág Festival in Bern, after which the Hungarian composer Máté Balogh dedicated a piece to her.

Since teaching has been a long tradition in her family, it was a matter of course for Ágnes Vass to share her experiences with others. She is passionate about accompanying and supporting young musicians on their way to a professional career. This aspiration has led to a three-year lectureship at the Bern University of the Arts as well as masterclasses at the Crescendo Summer Institute in Tokaj, Hungary. 

Since 2017 Ágnes Vass has been based in Bremerhaven, Germany as the associate principal flutist of the Bremerhaven Philharmonic Orchestra.
