“The secret of the vital power of Tchaikovsky’s music lies in the fact that there is virtually not a single province of his music–from the gems of Russian chamber music that issued from his pen to his greatest operas or symphonic poems–in which the appeal and effect of the music was less than in any other field. The convincing nature of Tchaikovsky’s melody is not dependent on the scale of the composition and its form, although the quality and character of the melodic material determines the form to a great extent. This is what makes any of the piano pieces from the famous “Four Seasons” cycle just as striking and titanic in scope as the First Piano Concerto.”
