Ilona Sekacz (Born 6 April 1948 in Blackpool, Lancashire, England) is a British composer of concert, film, television and theatre music.
Sekacz was born to a Polish father and an English mother. She studied violin and was a member of the National Youth Orchestra of Great Britain. Later she enrolled at the University of Birmingham, initially studying music but then changing to drama and theatre (Fuller 2006).
Sekcaz started her career making music for the theatre, spending three years with the Unicorn Theatre in London, for whom she composed musique concrète scores. She then worked for the Shared Experience company, and in 1982 composed music for the Royal Shakespeare Company's production of King Lear. Subsequently, she worked extensively with that company as a freelance composer, writing music for plays by Shakespeare as well as by other authors (Fuller 2006). She scored a number of television projects in the 1980s, including Alan Bleasdale's Boys from the Blackstuff (1982), and the 1992 series of Maigret (Fuller 2006).
In 1989 she composed an opera, A Small Green Space, to a libretto by Fay Weldon. Employing a mixture of amateur and professional performers, this opera was taken on tour throughout England by the English National Opera (Fuller 2006). Her instrumental works include orchestral and chamber music, as well as choral music composed mainly in aid of conservation and wildlife causes (Fuller 2006).
