She was born in Riga, in 1971. While being a student at Riga secondary School Nr 64, she attended the piano playing circle and the drawing studio of Helēna and Ivars Heinrihsons. She acquired her musical education in choral conducting department, initially, under the supervision of Inta Eizenberga at Jāzeps Mediņš Music Secondary School, then Professor Jānis Dūmiņš at Jāzeps Vītols Academy of Music. In 1995, she was awarded the Bachelor’s degree. Regarding vocal art, she acquired it under the supervision of Prof. Ludmila Rjabova – Brauna (1996-1998), and in the chamber ensemble class of Maija Krīgena un Pēteris Plakidis (1998-2000), achieving the Master’s degree in 2003. Concurrently, she finished her master’s degree studies in pedagogy at the University of Latvia (1997-1999).

Since 2000, she has participated in the stage productions of Latvian National Opera (initially as a choir artist, but since 2008 as a soloist). Predominantly, the repertoire of her roles includes the Russian opera music and the opera music of modern Latvian composers: Olga and the nanny at Yevgeny Onegin and Lyubova at Mazepa by Peter Tchaikovsky, Dunyasha at The Tzar’s Bride by Nikolai Rimsky-Korsakov, Smeraldina at Love For Three Oranges by Sergei Prokofiev, Grieta at The Heiress of Vilkaci by Bruno Skulte, the Mole-cricket at I Played, I Danced by Imants Kalniņš, Mother at Dauka by Andris Dzenītis, Polynesia at The Bird Opera by Jānis Lūsēns, The Black Lady at Mikhail and Mikhail Play Chess by Kristaps Pētersons, Alma at Valentina by Arturs Maskats, the Poetess (Master’s sister) at Walled In by Ēriks Ešenvalds, etc.

However, one of her most vivid artistic manifestations is exactly the genre of chamber music and renditions of various large scale vocal and instrumental pieces. Predominantly the interpretation of contemporary music and the music of Latvian composers lies at the centre of her attention, yet, she is also willing to sing the baroque and romanticism repertoire, paying great attention to the revelation of text and content. The singer is praised for her subtle sense of style, as well as for her amazing capability to interpret the music of the 20-th century. Many pieces by Latvian composers are dedicated to the voice of Ieva Parša.

In 2019, she has undertaken the duties of a member of the jury of Jānis Zābers 1-st International Vocal Competition.
