The work of composer Sivan Eldar has been described as “vividly imagined” (The Boston Globe), “ethereal” (Oakland Musical Examiner), “beautifully melancholic” (Opera Plus), “radiating with poetic sounds and silences” (ResMusica) and "with a unique sensitivity to dramaturgy" (Diapason). She has worked with many of today’s leading ensembles, including the Radio France Philharmonic Orchestra, Divertimento Ensemble, Ensemble Multilatérale, Exaudi Vocal Ensemble, Berkeley Symphony Orchestra, International Ensemble Modern Academy and Ensemble Musica Nova, at festivals such as Festival ManiFeste, Festival d’Aix-en-Provence, Royaumont Voix Nouvelles, Impuls Festival, Accademia Musicale Chigiana and Festival Tzlil Meudcan, at diverse venues including Boston’s Symphony Hall, Paris’ Maison de la Radio and Le Centquatre, Oslo’s Baerum Kulturhaus, NY's Bohemian National Hall, and Berlin’s RADIOALSYSTEM-V.
As a collaborator, she has worked frequently with dancers, directors and writers, with support from the Fulbright Foundation, Cité Internationale des Arts, Hearst Foundation, Ladd Prix de Paris, the Hertz Traveling Fund, ASCAP, the European Broadcasting Union, and IRCAM.
Sivan began her musical education in Tel Aviv at the age of 5, studying classical piano and voice. At the age of 15 she moved to New Mexico to continue her education at the United World College, where she studied composition while becoming involved in environmental and political work. She continued her studies in Boston at the New England Conservatory (BM), where she studied composition, piano and ethnomusicology, alongside courses in gender studies and ethics. In 2009 She moved to California to pursue her PhD in composition at UC Berkeley with Franck Bedrossian, Edmund Campion and Cindy Cox, with an emphasis in new media studies at the Center for New Music and Audio Technologies (CNMAT) and the Berkeley Center for New Media (BCNM). She then moved to Paris for training at the Institute de Recherche Acoustique/Musique (IRCAM) under Hèctor Parra (Cursus 2016-17), where she is currently composer in residence.
In addition to her work as a freelance composer, Sivan has served on the theory faculty of the Department of Music at UC Berkeley, and on the composition faculty of the John Adams Young Composers Program. She is currently based in Brooklyn and Paris.
