Erzsébet Seleljo was born in Transcarpathia and moved with her family to Hungary in 1994. She began her musical studies as a pianist at the music school in Uzhhorod, later continuing at the music school in Bonyhád under the guidance of her mother. At the age of thirteen—after seven years of piano studies—she took up the saxophone at the suggestion of her father, Jaroszlav Seleljo. From the very beginning, she achieved remarkable success: she won the Gold Medal and Festival Prize in the classical music category of the Helikon Festival (2000) and first prize at the 1st National Music School Saxophone Competition (2001).

After completing her secondary education, she studied briefly in the professional department of the Weiner Leó Secondary School of Music, where she won the Grand Prize of the Weiner Leó Competition (2003), first prize at the 1st National Secondary School Saxophone Competition, and the Jeunesse Special Prize.

She completed her higher education at the Royal College of Music in London, studying in the class of Kyle Horch, followed by a postgraduate year at the Konservatorium Wien Privatuniversität under Lars Mlekusch. During her years in London, she achieved notable competition successes, reaching the semifinals of the Torneo Internazionale di Musica and winning the Sonata and Concerto categories of the London Festival of Music and Drama, where she was also awarded the title Best Wind Player in the Concerto category. Her master’s and postgraduate studies were supported by scholarships from the Liszt Academy Network (2008) and the KLASSZ Associacion (2009).

After returning to Hungary, she was admitted to the Doctoral School of the Liszt Ferenc Academy of Music, where she earned her DLA degree in 2018 and completed her habilitation in 2025.

As a soloist, she has performed Glazunov’s Saxophone Concerto on several occasions, collaborating with ensembles such as the Liszt Ferenc Chamber Orchestra, Budapest Strings, and the Capriccioso Chamber Orchestra. She has also performed Frigyes Hidas’s Fantasia with the Győr Symphonic Band. In 2012, she gave the world premiere of András Gábor Virágh’s Necram for saxophone and orchestra with the Academy of Music Symphony Orchestra, and in March 2024 she performed the Hungarian premiere of Péter Eötvös’s Focus for saxophone and orchestra with Concerto Budapest.
Chamber music plays a central role in her artistic activity. In 2012, she co-founded the Duo SeRa saxophone–harp ensemble with Anasztázia Razvaljajeva. She regularly performs with her sister, pianist Irén Seleljo, and is also a member of the Trio ArmoniCorpus (saxophone–trombone–accordion). Her frequent chamber partners include percussionist Szabolcs Joó, organists András Gábor Virágh and Márton Levente Horváth, violinist Vlad Maistorovici, among many others. She has been a guest at numerous chamber music and saxophone festivals, including the Vibrate! Festival (Brașov), Opus Amadeus (Istanbul), Academic Festival (St. Petersburg), Saxophobia Bratislava, Alpen Classica Festival (Bressanone), Poznań SaxFest, and Szczecinek SaxFest.

Her repertoire ranges from Renaissance and Baroque transcriptions through original saxophone works to contemporary music. Her artistic profile is strongly defined by her commitment to contemporary repertoire: in recent years, she has premiered more than fifty solo and chamber works. Numerous Hungarian composers—including Zoltán Jeney, László Sáry, Tibor Szemző, Miklós Maros, András Gábor Virágh, Máté Balogh, Péter Tornyai, and Krisztina Megyeri—have written new works for her or with her collaboration. She has also introduced many international contemporary works to Hungarian audiences, including compositions by Berio, Aperghis, Tanada, Gervasoni, and Senk. In recognition of this activity, she received the Artisjus Award from the Hungarian Copyright Society in December 2024.

She regularly collaborates with leading Hungarian contemporary music ensembles such as UMZE and MIKAMO, and has performed with major Hungarian symphony orchestras, including the Hungarian State Opera Orchestra, the Hungarian National Philharmonic, the Hungarian Radio Symphony Orchestra, Concerto Budapest, the MÁV Symphony Orchestra, as well as the Győr and Savaria Symphony Orchestras.
Alongside her artistic career, her pedagogical activity is also significant. She teaches saxophone at the Bartók Béla Secondary School of Music in Budapest and at the Liszt Ferenc Academy of Music. Her students regularly achieve outstanding results at national and international competitions. She has given masterclasses at events such as the International Wind Days (Dunaföldvár), Saxophobia Bratislava, and the Alpen Classica Festival, as well as at numerous European music academies. She has also served as a jury member at several competitions, including the Josip Nochta International Saxophone Competition (Zagreb), the FEMUS International Competition (Subotica), and various competitions in Hungary.
