This thesis deals with suite for accordion solo by authors of the Russian composition school and specific problems associated with their interpretation at music schools and conservatories. The main goal is to draw attention to the Czech, Slovak and Russian accordion music scene and to analyse chosen accordion suites of three Russian composers. Furthermore, suitability to involve these suites into the repertoires of pupils at elementary music schools and of conservatories students is considered. The general aim is to introduce accordion not only as a folk instrument, but also as a concert one.

This dissertation work is concerned with Czech composers who composed for the solo accordion. These composers cover a range of individual generations of composition from the earliest born through to the youngest. There is a brief introduction to each composer along with their compositions for solo accordion including the characteristics of each individual composition and the circumstances of their creation.
