Partita Party is the brainchild of Atar Arad. It is a new collaborative composition for solo viola based on J.S. Bach's Partita No. 2 for Solo Violin. Atar asked four of his friends (and former students) to join him in writing movements jointly inspired by Bach's masterpiece and Atar's Ciaccona, which he wrote for the 2021 Hindemith International Viola Competition. The other movements of Partita Party were written by Duncan Steele (Allemanda), Yuval Gotlibovich (Corrente), Melia Watras (Sarabanda), and Rose Wollman (Giga), each using Atar's starting note and tone row and using the structure of Bach's movements. This innovative new work was recorded by the composers at Indiana University in October 2023.
