The instrument famously associated with Mozart is the piano, particularly the fortepiano, which was the precursor to the modern piano. Mozart was a prolific composer who contributed significantly to the piano repertoire, writing numerous sonatas, concertos, and chamber works. His compositions showcase the instrument's expressiveness, technical capabilities, and its evolving role in classical music. Mozart's mastery of the piano influenced later composers and established the groundwork for future piano music. The fortepiano, with its lighter touch and different tonal quality, was integral to the classical music genre during Mozart's time.
