Sonata ‘June-December’ for violin and piano was composed in the course of 2003-2006. The title on the one hand simply reflects the time when two movements of the piece were finished, but on the other hand it also indicates the conflicted character of Sonata. The first main impulse to write this piece was the desire to meet the challenge of creating music in a classical musical form. The second main impulse was the need to square up with the above-mentioned desire and finally be free from the complex of not being able to measure up to the heritage of the great music history. So, there are two drives present in this piece. The first drive is to be consistent, to create, develop and sum up, and the other one is to be unpredictable, to create, contrast and destroy. Like the themes in the classical sonata form, these two drives meet and fight with each other. I don’t know which one wins, but I know that the complex is still there.
