Orbán was born in Transylvania Romania in 1947 and studied composition at the music academy of Cluj-Napoca, a par excellence multicultural center of Transylvania. After graduating in 1973, he taught music theory at the same institute. Since 1979, Orbán has lived in Hungary, teaching composition and music theory at the Liszt Ferenc Music Academy of Budapest.

Up to now Orbán’s work was dominated by oratorical compositions and choral works. His instrumental compositions vary from symphonic pieces, instrumental-vocal combination (songs with accompaniment of one or more instruments) to brass music and, of course, chamber music.

Besides orchestral and chamber work, his main interest is choral music such as oratorios, masses, cappella or accompanied composition for Latin, Hungarian and English sacred and secular text. Orbán has composed more than 140 choral pieces, which are sung all over the world.
