Born in Lyon on September 1st, 1986, it is after studies of engineer that Yann Phayphet decides to dedicate to the music and integrates the ENM of Villeurbanne, and then the National Academy of Lyon at the instigation of Jérôme Regard.

Multiplying the projects at the double bass and at the electric bass within various groups with very different esthetics, such as Electrophazz (nude soul / hip-hop), Mahssi (Latin fusion), Thibault Saby quartet (modern jazz), and many more collaborations, he develops a jazz sound with a very binary background, what turns out uncommon for a double bassist.

It is mainly with EYM trio he shows himself on the French and European stages. He played in Jazz à Vienne, Fort en Jazz, Vaulx Jazz, Jazz in Vannes, Jazz à  Oloron, Jazz sous les chataigniers, Tournai Jazz Festival, Moz' Aïque Festival, Altitude Jazz Festival, Golden Jazz Trophy, summer Festival des nuits d’été, Cosmo Jazz, Nancy Jazz Pulsation, un Doua de jazz.

He also participated in tours in the United States, Mexico, Italy, Spain, Czech Republic, Slovenia, Slovakia, Croatia, Belgium, Switzerland, Germany etc.

With EYM trio he record "Genesi"  in 2013 and is prize-winner of the springboard young talents of the Festival Jazz in Saint Germain des Prés, the national competition of The Defense Jazz Festival and the Festival Jazz to Gexto.
