Sarah Buechi was raised in a musically active family and started playing the violin and piano at the age of five. After an award for a self-written musical theater she decided to take music as a profession. After graduating from Lucerne's prestigious Musikhochschule with two distinctions, she took a lengthy sabbatical in Bangalore immersing herself in South Indian Classical Music and Rhythm with concerts on festivals, radio and television. The results are apparent in her use of its demanding rhythmic and vocal techniques in a Jazz context. Out of her own projects THALi (Unit Records, 2010) is the first one that brought Sarah Buechi to the attention of the Swiss Jazz Scene and intern to international musical collaborations with outstanding personalities like Steve Coleman, Dave Liebman, Lucas Niggli, Nils Wogram, Ronan Guilfoyle, Christy Doran, Christoph Haberer, Christoph Stiefel and Matthias Schriefl. This brought her onto concerts, workshops and tours within Europe, South Amercia, USA, Canada, China and India. Sarah has been head of the Jazz vocal department at Newpark Music Centre, Dublin for four years (2008-2012), lived after that in London (2013-2015) and studied at the Complete Vocal Institute, Copenhagen (2012-2015). In Switzerland in 2005 she was awarded the Friedl-Wald-Foundation prize and three times she was awarded the Irish Travel and Training award for musical researches in Ghana, Paris, New York and Copenhagen.
Back in Switzerland, she taught at the MKZ, Zurich (2015-2018), at the Jazz vocal department of the WIAM, Winterthur (2016-2018) and at the vocal department of the Musikhochschule, Lucerne (HSLU) since September 2018.
In November 2022 she released her sixth album as a band leader on Intakt Records and collaborates with established musicians in various other projects around the world.
