A violin sonata is a musical work that features the violin as the primary instrument. It typically consists of three or four movements and is played by a solo violinist accompanied by a piano. However, there are alternate names for this type of music. For example, a violin sonata is sometimes called a sonata for violin and piano. Similarly, it is sometimes referred to as a fiddle sonata or a violin-piano duet. Other synonyms include a partita for violin and keyboard, a duo sonata, or simply a sonata. Despite the different names used to describe this musical genre, they all refer to the same type of music - a beautiful harmony between violin and piano.
