Nikolai Klenovsky (1857–1915) was a Russian conductor, composer, and teacher. He was born in Odessa and died in Petrograd.
He studied composition at the Moscow Conservatory with Pyotr Ilyich Tchaikovsky and Nikolai Hubert. He assisted Nikolai Rubinstein in managing the student orchestra, then worked as an assistant director of the Court Chapel and as an inspector of its regent classes. Klenovsky also worked with Yuri Melgunov to collect and arrange Russian folk songs.
In 1893, Klenovsky organized a Moscow concert of songs from different peoples that he had arranged; these were later published under the title Ethnographic Concert. His work in Tiflis as a conductor and collector of Georgian folk songs contributed to the development of Georgia’s musical culture. His students included Vladimir Rebikov and Armen Tigranyan.
His works include the ballets The Pleasures of Hashish (1885), Svetlana (1886), and Salanga (1900); music for the dramatic works Messalina, The Star of Seville, and Antony and Cleopatra; the orchestral suite Mirages; two coronation cantatas; two cantatas for Pushkin celebrations; a piano suite; Georgian songs for solo voice, chorus, and orchestra; and a Georgian liturgy for unaccompanied voices, with Georgian and Russian texts.
