This article attempts to present sketches of the compositional creativity of Alexandr Boris Mulear (1922–1994), who is one of the most important figures of the music culture in the Republic of Moldova and belongs to the older generation of composers, as his glory years were between 1950 and 1980. The composer’s record contains a valuable artistic heritage that is appreciated by performers but the study of his works is not in the center of interest of musicologists yet. However, the article will present some examples of the Mulearian creativity. Analyzing the composition portfolio of A. Mulear, the author shows that chamber works predominate for the most part in his creativity, including suites, quartets, sonatas, miniatures and musical pieces, with a wide range of instrumental groups: from the duo (violin and piano, piano and voice) to the symphony orchestra. In conclusion, it is noted that the composer manifested himself in an original way in chamber music, which is more innovative and bright and reveals diverse forms of classical music in terms of style and genre.
