The statement that all composers from the Classical era composed in the style of Haydn, Beethoven, and Mozart is false.
1. **Explanation**: While Haydn, Beethoven, and Mozart were prominent composers of the Classical era known for their significant contributions to music, not all composers of that time period composed in their specific style.
2. **Variety in Compositional Styles**: The Classical era saw a diverse range of composers with different styles and approaches to music composition. Composers such as Carl Philipp Emanuel Bach, Christoph Willibald Gluck, and Luigi Boccherini, among others, had distinct musical styles that differed from the works of Haydn, Beethoven, and Mozart.
3. **Innovations and Individuality**: Each composer during the Classical era brought their own innovations and unique characteristics to their compositions. While some composers may have been influenced by the works of Haydn, Beethoven, and Mozart, they also explored their own creative paths and contributed to the rich tapestry of Classical music.
In summary, while Haydn, Beethoven, and Mozart were influential figures in the Classical era, it is incorrect to state that all composers from that period composed exclusively in their style. The diversity and individuality of composers during that time led to a wide range of musical expressions beyond the works of these three iconic composers.
