Lior Navok (born September 6, 1971) (Hebrew: ליאור נבוק) is an Israeli classical composer, conductor and pianist.

[4] His stage music includes two operas, The Bet, based on a short story by Anton Chekhov, and An unserem Fluss (By Our River).

Lior Navok’s musical language employs modality and expanded tonality, avoiding serial techniques and mathematically-predetermined pitch sets.

Michael McDonagh’s referred to “echoes [of] Debussy and especially Ravel”[11] in Navok’s music, especially in his relatively early works, such V5[12] and the Quartet for flute, clarinet, bassoon and harp.

His more intimate vocal works are written for ensembles ranging from standard Lieder scoring (single voice and piano), through more unusual combinations (e.g., soprano and percussion in the semi-theatrical Dialogues[30]), to voice and orchestra, setting texts in various languages and traditions, including Biblical texts in the original Hebrew; Israeli poets Leah Goldberg, Dan Pagis and others; Emily Dickinson, Antonio Machado, and others.

The resulting compositions – Urban Nocturnes,[32] Inner Landscapes,[33] From the Log of a Longing Captain[34] and Time Junctions[35] – were released as audio recordings.

Together, these three musicians form the Butterfly Effect Ensemble,[36] which specializes in creating live scores for silent films from the early days of the cinema up to 1929.
