Tolga Yayalar (b. 1973, Istanbul) is a composer whose work is driven by a single question: what happens to musical material as it passes through time? Across his output, this transformation takes psychological, historical, physical, and technological forms, but the underlying concern is constant. Sound is treated as the trace of something already changed, and composition becomes a way of exposing the distance between an origin and its result. His music spans orchestral and chamber writing, fixed-media electroacoustic composition, and large-scale multimedia theatre.
Since 2021, space has become an explicit structural concern in his work. Composing in high-order ambisonics and immersive multichannel environments, Yayalar treats distance, proximity, and depth as carriers of musical meaning alongside pitch, rhythm, and timbre, so that spatial structure becomes a means of articulating time itself. This practice runs from his fixed-media composition through his recent multimedia theatre, where immersive audio, video, lighting, and text are integrated into a single dramaturgical system.
Recent works include Four Sacred Spaces (2022), for three string quintets distributed across the stage and built entirely from open strings and natural harmonics; Echoes and Ashes (2024), for large ensemble and six-channel electronics, after Nâzım Hikmet's Kuvâyi Milliye; and the ongoing Impulse Impromptu series (2021–), in which a single sounding object (the kanun, the koto, a music box) is recorded, sampled, and spatially transformed into an interior sound world. His multimedia monodrama Dido (2021), with text by Korhan Başaran, has toured Turkey, Austria, Greece, Bulgaria, Italy, and the United Kingdom; their seventy-minute production Trojan Women followed in 2025.
Yayalar's music has been performed across the United States, Europe, Asia, and Latin America by ensembles including Le Nouvel Ensemble Moderne, Alarm Will Sound, the Callithumpian Consort, the Ying Quartet, the Orchestre National de Lorraine, and Hezarfen Ensemble, and presented at festivals such as MaerzMusik Berlin, the Beethovenfest, Ars Electronica, Acht Brücken Cologne and the New York City Electroacoustic Music Festival. His honors include the League of Composers/ISCM Composition Award, the Donald Aird Memorial Prize, the Blodgett String Quartet Composition Prize, and the George Arthur Knight Prize.
He completed his Ph.D. in composition at Harvard University in 2010, following studies at Berklee College of Music and Istanbul Technical University. He has been on the faculty of Bilkent University in Ankara since 2011, where he has chaired the music department since 2017 and is a co-founder of Bilkent Composition, the university's community of composers, which brings them together for concerts, talks, workshops, and residencies. In 2018, he founded BUSEAM, Bilkent's electroacoustic music studio, and has curated its concert series ever since.
