Speaking of classicism in European musical art, we mean the work of such great and brilliant composers of the 18th century as J. Haydn, W. Mozart, L. Beethoven. They are the founders of European musical culture. The direction of the classical school in music has become the most fruitful in the history of European musical culture. Each of the representatives of the European culture of the XVIII century was itself an individual. Haydn and Beethoven were more instrumentalists, and Mozart proved himself not only in the instrumental, but also in the operatic works. European musical culture of the 18th century was a wonderful environment for the development of new ideas and attitudes. The composers of the classics in their work summed up not only all that European music reached at that time, but also they embodied their new creative discoveries in music. Characteristic features of European classicism are the universality of artistic thinking, consistency, clarity of artistic form, an organic combination of feeling and intelligence, tragic and comic, ease of expression. Composers of European classicism could express even the most complex content in a simple, understandable language. During this period, the achievements of musical culture were formed, such as classical musical genres and principles of symphony. This was the most significant achievement in the musical culture.
