Closely related to the world of the choir, both as a chorister and a composer. Eva Ugalde was born in San Sebastian where she later went on to study Musical Composition and Choir Direction with Gotzon Aulestia and Miguel Amantegi respectively.

Her work is principally centred on choral music and she has written several pieces for female voice choirs of which one of the most outstanding is “Tximeletak” (Butterflies) written to the words of the Basque author Bernardo Atxaga (National Prize for Literature 1988) and which premiered at the 60th San Sebastian Musical Fortnight in August 1999 as part of the season “Music of the 20th Century”. She is a member of the female voice choir "Kanta Cantemus Coroa" conducted by Javier Busto.

Although her music is principally tonal, the influence of the harmonics of jazz and the rhythm of New Age are also notably present.
