Juline Florentino is a french-brasilian soprano, born in Versailles. She grew up in Strasbourg where she started her musical upbringing with the harpsichord. In the course of her many experiences, she has had the chance of singing, among others, under the direction of Theodore Guschlbauer and Marko Letonja. Since 2022, she lives in Berlin where she studies at the Universität der Künste Berlin in the class of Joshua Whitener.

Juline's voice stands out thanks to its warm and suave tone coupled to thrilling yet easy highs. Her nonchalant and subtle voice married to her zesty character perfectly suits to Mozart's roles such as Blonde (Die Entführung aus dem Serail), Susanna (Le Nozze di Figaro) or Despina (Così fan tutte).

Stimulated above all by collaboration with other talents, she starts a Guitar-Voice duo in 2020 with Valentin Weber. They win the second price of the Concours de Musique de Chambre de l'Abrapa in 2021. This collaboration will lead them to a widened repertory going from Dowland, Schubert and Villa-Lobos all the way to contemporary repertory together with some creations of Valentin himself. They were to be heard in April 2022 in their “Sortilège” concert in Strasbourg. Since 2025, Juline has been working closely with Zoé Barbay with whom they started a piano-voice duo between Lyon (FR) and Berlin (DE). Their shared and extended passion for lied and melody brought them to a masterclass hosted by Philippe Biros in August 2025.

It is through early music that Juline started her musical education and it still, up to this day, takes a special spot for her. Between 2015 and 2025 she sang at numerous concerts and early music programs in the likes of the Concerts aux chandelles accompanied by Gilbert Verge-Borderolle and Géraldine Bruley in France's Haute Garonne region. In 2022 and despite COVID restrictions, she sang part of a Soprano role in Pergolesi's Stabat Mater. In the list of oratorios, she was heard in Der Tod Jesu from Graun, a concert organized in Berlin and directed by Kai Uwe-Irka. Her repertory is also composed of the soprano parts of Bach's Passions and Christmas Oratorio.

New music is not left behind, it is through the teaching of Françoise Kubler that Juline falls in love with it. She has had the chance of creating different pieces for choir and two Lieder of Lukas Mertin originating from the Cycle for Soprano and Bass Op2.

Juline makes her scenes debut at the age of 12 where she plays an extra in the Huguenots of Meyerbeer staged by Olivier Py. This experience left a mark deep within her and defined her future until today. In the course of her years at the maîtrise de l'Opéra national du Rhin, she will participate in different productions, both in the choirs and as a solist such as in The Cunning Little Vixen (La Petite Renarde rusée) from Janáček staged by Robert Carsen. In 2025, it is in a production of Street Scene from Kurt Weill that Juline took part as an understudy for Rose as well as Salvation Army Girl 1, Nurse 1 and Laura Hilldebrandt.
