Christina Daletska was born in Lviv (Ukraine).

The artist has been described by the press as "phenomenal" and "irresistible". She is a human rights activist and official ambassador for Amnesty International Switzerland. She has also demonstrated her exceptional musical skills in the repertoire of the late XX and XXI centuries, including in several world premieres. Daletska's vocal range is over 3 octaves.

The artist made her operatic debut at the age of 23 as Rosina in "Il barbiere di Siviglia" at the Teatro Real Madrid; one year later she sang at the Salzburg Festival.

The artist regularly performs with renowned ensembles and orchestras such as the Arditti Quartet, Ensemble Intercontemporain, Swedish Radio Symphony, Klangforum Wien, MusikFabrik, Collegium Novum and many others.

Christina Daletska studied violin with her mother and performed as a soloist at the Royal College of Music in London at the age of 10; she played the violin concertos by Mendelssohn, Tchaikovsky and Beethoven before her 18th birthday. In 2006 she began her vocal studies with Ruth Rohner in Zurich and won three prizes in three international singing competitions just one year later.
