At the turn of the 18th and 19th centuries, Europe experienced numerous political and social changes. The outbreak of the French Revolution in 1789 not only entailed changes in yet stable state structures in a short time, but also influenced the normative canons in art, which resulted in a new epoch - Romanticism. Nowadays, we find its ideas in poetry, painting, and music. Those arts drew from each other; therefore, they were intertwined and they complemented themselves by expressing interior spiritual and emotional states of their authors. It is very interesting to see in this background the person and works of Franz Xaver Mozart - a pianist and composer, the youngest son of the great Wolfgang Amadeus.
