The role of concert-performing, musical-pedagogical and compositional work of Vyacheslav Borysovych Tsaits in the evolutionary development of the Lviv oboe school is highlighted. The historical aspect of the formation of the Lviv oboe school, founded in 1853 by the German professor Karl Brunhofer, is considered. The evolutionary development of its established traditions on the basis of the activity of the Czech oboist Franz Fugl is analyzed. Individual features of V. B. Tsaits's concert-performing style are revealed, which have a leading importance in the evolutionary development of the Lviv oboe school (deep philosophical knowledge of a musical work and awareness of its idea and content; filigree-brilliant performance technique; virtuoso mobility and easy mastery of staccato stroke; rhythmicity, excellent intonation, extremely wide range of dynamic shades, perfect sense of form, impeccable knowledge not only of the soloist's part, but also of the orchestra, phenomenal reading of notes from the sheet, magical timbre of the instrument in different registers, sense of musical form). The individual features of V. B. Tsaits's musical and pedagogical style, the observance of which will allow to achieve even better results in the education of the current generation of oboists, are determined: reproductive methods of work on sound, improvisations in different tones, sequences and special melodic exercises throughout the oboe register; persistence in achieving accurate textural execution of piano accompaniment, etc. The Concertino for oboe with orchestra by V. B. Tsaits is analyzed, which allows demonstrating the artistic and creative and virtuoso-technical potential of the soloist-instrumentalist, the multifaceted expressive-timbre specificity of the instrument. At the same time, it is substantiated that virtuosity should not be an end in itself, but should become a means of revealing the figurative and emotional content of this concert work, which generally reflects the impressions of reading the works of Antoine de Saint-Exupery (“The Little Prince”, “Wind, Sand and Stars”, “Southern Mail”). It is proved that V. B. Tsaits's Concertino plays a special role in the evolutionary development of the Lviv oboe school, as it is one of the most favorite concert works of its representatives
