OONA GUINO
Jazz singer and vocal technique instructor
Born into a family of artists, Oona began singing as soon as she learned to speak. At the age of 14, she took her first singing lessons before joining the Jazz Department of the Aix-en-Provence Conservatory. After graduating from high school, she returned to Paris and enrolled in the conservatories of the 9th and 6th arrondissements, where she continued her jazz studies. There, she studied harmony, ear training, and voice with Sarah Lazarus.
Alongside her studies, she performed in Parisian clubs and restaurants as part of various projects featuring jazz, soul, and reggae standards.
After returning to the south of France in 2016, she continued her training at the Marseille Regional Conservatory (CRR), then at the IMFP in Salon-de-Provence, graduating in 2023.
While continuing to perform on stage, she also founded her own original music project with musicians from the region.
In addition to her technical expertise in harmony, breathing, listening, and improvisation, Oona’s teaching philosophy focuses on authenticity. She guides her students in discovering and developing their own sensitivity and emotional expression, helping them achieve vocal, musical, and artistic accuracy. Her honest and intuitive approach is tailored to the individuality of every student.
Tiffany Muzellec
Jazz singer, vocal technique instructor, and sound engineer
After initially studying to become a sound engineer, Tiffany ultimately decided to pursue her first passion: music. In 2022, she joined the Jazz Department of the Marseille Conservatory. She has been singing since childhood and developed her voice largely through self-teaching, alongside learning bass guitar, guitar, and piano.
She trained in jazz vocal technique with Élise Vassallucci and further developed her breathing techniques and body awareness with Monique Zanetti, a singer specialising in Baroque music.
Tiffany’s teaching approach is rooted in kindness, body awareness, and attentive listening. She encourages students to explore their voices through movement and vocal experimentation, with a strong emphasis on intention, grounding, and expressiveness.
Her jazz background also enables her to introduce concepts of harmony and improvisation, enriching each student’s vocal journey.
