Music is a wonderful art that is created specifically to give people joy. Every person has some favorite tunes that cheer him up and make him feel better. Sometimes one can mourn for a while to a music being in a melancholy mood, because it can help us to cope with our problems. Perhaps therefore, I like music so much and just can't imagine my life without it.

Most of all I like to play the guitar. I learnt the first guitar chords in childhood: my dad taught me. Then I began to attend a music studio and to take classes of playing this musical instrument from a professional teacher. It was at these classes, when I first tried to play in a band. When I was 10 years old, we organized a concert for our parents. During the performance, I played the lead guitar, our teacher accompanied me on the piano, and two other guys were in the composition of the rhythm section, i.e. played bass guitar and drums. It was a wonderful performance, during which I realized exactly what I wanted to do next.

After a couple of years, my classmates and I organized our own rock band. Now the main part of our repertoire consists of compositions of favorite performers, but it also has some of our own stuff. During its existence, our team managed to appear on the stage of the urban youth club and on some other venues. We have many rehearsals and are constantly in the process of creative music search.

Music classes for me are the main source of power and inspiration, so I intend to evolve in this direction. Friends also support my enthusiasm, so I think our band will continue its existence and after finishing school.
