Leila Schütz began her musical education with the violin, which she studied in Paris with professor Florin Szigeti. She started singing at the age of 12, then trained at the Nadia and Lili Boulanger Conservatory (Paris) with Elsa Maurus and Doris Lamprecht. Her vocal training then took her to the Hochschule für Musik in Dresden, where she completed her Bachelor's degree in Yamina Maamar's class before joining the opera studio at the Rostock Theatre where she also earned her Master's degree in Martina Rüping's class. She also studied German Lieder with Olaf Bär, Bo Skovhus and the pianist Daniel Heide.
Leila Schütz was a scholarship holder of the Ad Infinitum foundation and is also a laureate of the Lion's Club prize from the International Academy of Singing in Saxony.

Her participation in William Christie's production of Dido and Aeneas, directed by Deborah Warner at the Opéra Comique when she was only 12 years old left a deep mark on her and strengthened her enthusiasm for baroque music. In November 2023, she was awarded three prizes at the Cavalli Monteverdi competition in Cremona, where the jury, chaired by Laurent Brunner, brought together prominent musicians such as Michael Chance, Francesco Corti, and Antonio Greco. As a result, she was invited to perform at the Orfeo Week 2024 Festival directed by Raffaele Pe. In early music masterclasses, she received advice from musicians and singers such as Emmanuelle de Negri, Paolo Zanzu, Stéphane Fuget, and Claire Lefilliâtre, with whom she perfected her mastery of the style. Additionally, she trained in baroque dance with Margit Legler. 

Winner of three awards at the Cavalli Monteverdi competition in Cremona 2023, French soprano Leila Schütz was a member of the Opera Studio at the Rostock Theatre (Germany) from 2023 to 2025. She performed the parts of Frasquita (Carmen, Bizet) under the baton of Markus Bosch, the Sandman and Dew Fairy in Hänsel and Gretel (Humperdinck), Amore in Gluck's Orfeo ed Euridice, Caterina Cavalieri in the play Amadeus (Peter Schaffer), and the four female roles in The Wizard of Oz by American composer Lucy Landymore.

In the opera field, she also sang the Queen of the Night in Mozart's Magic Flute with different youth ensembles (Opernstudio Belcanto, Junge Kammerphilharmonie Sachsen) as well as her lesser-known counterpart, Hersilia, in a production of Orpheus und Euridike by Johann Gottlieb Naumann (1741-1801), with the Elblandphilharmonie in Dresden. She played Zerbinette in the hybrid opera Dafne auf Naxos by Richard Strauss and Heinrich Schütz, with the Serkowitzer Volksoper, blending opera, operetta, and baroque music. She debuted at the Semperoper in Dresden in the role of a eunuch in The Nose by Shostakovich directed by Peter Konwitschny. She also sang the part of Gretel in a student production of Hänsel und Gretel and took on the role of Olympia (The Tales of Hoffmann) at the Mittelsächsisches Theater ball.

Leila Schütz formed a singing-piano duo with her sister Bella Schütz, with whom she explores the repertoire of Lied and French melodies dear to her heart. They performed together in concerts organized by the Orphée Musique association in Paris and at the Oradea Philharmonia (Romania).

Leila participated in the musical and theatrical performance Lebende minus Tote at the Grand Theatre in Hellerau combining baroque music with contemporary creations, and she sang the title role in the Glikl-Oratorye, a Yiddish creation by American composer Alan Bern performed at the Kaisersaal in Erfurt, blending early music with jazz, klezmer, and 20th-century Lied.

Alongside her musical studies, Leila obtained a Master's degree in Theatre Studies from the Sorbonne-nouvelle (Paris) in 2018, dedicating her thesis to Ravel's The Child and the Spells. As a co-founder of the "Sternflammende Oper Wien" company, Leila also debuted as an opera director. Her staging of Mozart's The Magic Flute was performed at the Theatre of the Vienna Boys' Choir (MuTh) in spring 2019 with young emerging artists. She continued this passion alongside her singing career by co-directing the youth production of Hansel and Gretel at her university in Dresden, where she also designed the costumes and created the makeup.
She is writing her own cabaret show that will blend opera, Yiddish music, baroque dance, and comedy.
