Mansi (Clemensa) Barberis (1899–1986) was a Romanian violinist, music educator, conductor and composer.
Clemensa Barberis was born in Iaşi and began to improvise on the piano at an early age. When an aunt transcribed one of the pieces, composer George Enescu recommended that Barberis take theory lessons. She studied with Italian professors in Iaşi and later studied violin, voice, and composition at the George Enescu Conservatory.
Barberis graduated from the Conservatory in 1922. She married a physician and had a daughter, which she left with her parents so she could continue her studies in Berlin. She returned to Romania after a year and took professional employment, but later continued her studies in Paris during three sessions, studying voice, conducting, opera, composition and orchestration. In 1936 she also studied voice briefly in Vienna with Max Reger.
Barberis' music is strongly influenced by Romanian folk music. She wrote over one hundred art songs, symphonic music, four opera, instrumental music and choral works. Selected compositions include:
- Itinerar dacic (1976) to verses by playwright Dominic Stancu
- Destin de poet (1981) to verses by Mihai Eminescu
- Kera Duducea (1963) opera
- Apus de soare (Sunset) (1961) opera
- Rondelurile rozelor (1982) song cycle to verses by Alexandru Macedonski
Barberis published an autobiography, Din zori până în amurg (From Dawn until Dusk)
