Chamber Choir Sireen was founded in November 2011 by a group of friends united by a long-standing passion for choral singing.

Renowned for its distinctive sound, Sireen combines the radiant timbre of a female choir with the clarity and intimacy of chamber music. Every singer contributes her unique artistic voice to the ensemble, and each member is an accomplished soloist in her own right. With just twenty singers, Sireen is equally at home filling large concert halls with a rich, expressive sound and creating moments of extraordinary intimacy in the most delicate pianissimo.

The choir brings together women from a wide range of professional backgrounds, resulting in an ensemble defined by individuality, versatility, and artistic curiosity. Although its members are not professional musicians, they approach music-making with exceptional dedication, experience, and musicianship. This has made Sireen a valued partner in projects that reach beyond traditional choral boundaries, from theatrical productions and operas to contemporary performances and experimental artistic collaborations.

Over the years, Sireen has performed in churches, concert halls, industrial venues, and on Estonia’s seashores. The choir’s adventurous spirit and independent character allow it to move effortlessly between lush Romantic repertoire, contemporary music, and unexpected musical genres. While innovative in its artistic approach, Sireen remains firmly committed to musical excellence and a refined choral sound.

Its repertoire spans from early music to contemporary compositions, with a particular emphasis on collaborations with talented Estonian composers of younger generations.

Sireen has released two albums, Terra Incognita (2016) and Terra Feminarum (2023). The choir can also be heard on composer Rasmus Puur’s album Thoughts of a Young Woman (2017).

Sireen has achieved significant success at choral competitions in Estonia and abroad, receiving top awards at the Estonian Chamber Choir Festival (1st Prize in 2016 and 2026; 3rd Prize in 2018 and 2022), the Tallinn International Choir Festival (2nd Prize in 2013, 2015, 2017, and 2019; 1st Prize in 2025), the EBU international choral competition Let the Peoples Sing (1st Prize in 2019), and Kaunas Cantat (3rd Prize in 2026).

The choir’s conductors have included Tiiu Sinipalu, Ülle Abner, and Nele Erastus. Since 2022, Sireen’s Artistic Director and Conductor has been Laura Štoma.
