More and more research is pointing to the varied and improvisatory performance style of classical music — especially that of Mozart. It helps to dismantle the urtext aura of the official, printed music. Robert Levin provides exemplary research on the playing style of Mozart. Mozart played freely, in part enabled by his tremendous genius, in part because of performance practices of the time. For example, at the time, singers were expected to improvise passages of music in a single breadth. Likewise, Mozart would improvise throughout his pieces in short quick passages. He was a lover of singers and took inspiration from them.
