After studying at the Bordeaux Conservatory (with a degree in saxophone and composition studies), Jean-François Petitjean listened to and studied the great jazz masters developing a taste for free improvisation.
In 2007 he learned about soundpainting which he practices regularly as a musician or soundpainter. His encounters with Walter Thompson, the creator of Soundpainting, and François Jeanneau allowed him to realize the importance and qualities of this language.
He currently plays in various jazz bands, including : Healing Orchestra (Free jazz), Imaginary Africa (Jazz/world music), Yosh! (Saxophone Quartet), Castro Quartet (Jazz), and performs at various venues in France and Europe.
As a composer, he has written several pieces of contemporary music, musical tales, show music (dance, theatre...) and short films.
After obtaining the State Diploma in Jazz and Soundpainting certification in 2010, he divides his time between teaching jazz and improvisation, and working on personal projects.
He plays his Syos mouthpiece on "Origin ", the new Castro Quartet album released in September 2021.
