The genre of piano sonata is one of the most significant sphere in Alexander Skriabin's (1872–1915) creation. Twenty years lay between his First and Tenth Sonatas. It occured to be the age satiated with impetuous fruitful ideas, leading the composer sometimes to new contrasting spiritual aims. The sonata-symphonic structure attracted Skriabin by its inner diversity and capacity, able to embody discrepant unity. Skriabin was the true composer-pianist. Therefore he interpreted the sonata structure rather random, as if being begotten again and again. Those were his philosophical and symbolic conceptions to have become his guides both in life and art.
