Kharkiv instruments made by Poltava bandura maker - Hryhory Paliyevetz. The Capella had its name changed to the "Exemplary Bandura Studio of UKRFIL". The eleven members of the Studio were joined by a twelfth - Ivan Boretz in 1928, who came to study at the studio from the Kharkiv Bandurist Capella. The studio functioned for 18 months. Each week Volodymyr Kabachok would travel to Kharkiv from Poltava to pick up the weeks assignments from Khotkevych. Khotkevych would visit once a month to review the progress of the students. The technique of the members of the Capella grew considerably and the new repertoire composed and arranged by Hnat Khotkevych opened up new aspects of the bandura previously never explored. Over 20 new pieces were prepared. These included such works as the "Poem about Bayda", and the "Duma: Storm on the Black Sea". At the completion of the studio period with Hnat Khotkevych the group had a concert examination in Kharkiv at the Korolenko Library Auditorium on 22 January 1930, attended by musical dignitaries of Ukraine. After a successful performance the members began to work professionally as artists in a full-time capacity. After the performance the Capella was renamed "The State Exemplary Bandura Capella of the Ukrainian SSR". In 1930 concerts were planned with the Capella being accompanied by a symphonic orchestra. Khotkevych made preparations composing a number of works for the Capella with full symphonic accompaniment. The performance however did not take place. This period coincides with a growing period of anti-Ukrainian actions by the Soviet government. Concert exploitation In 1931, after a successful performances in Moscow, the ensemble was chosen to be the first artistic group from the Soviet Union to tour North America. In order to prepare for a tour of the United States the received new instruments with tuning mechanism and dampening mechanisms made by Hryhorij Paliyevetz. Despite a deposit of $15,000 being paid, the announced tour did not take place. Instead, the group was exploited by UkrFil (The Ukrainian Philharmonic concert organization) giving some 28 concerts a month. Most of the concerts seemed to take place in areas which had little interest in the bandura and bandura music. Severe restrictions were also place on the repertoire redirecting the group away from historic repertoire and focussing more on Soviet mass songs. For a brief time however, the ensemble became extremely popular and demonstrated the direction for further development
