What instruments did Henri Chaix play?

### Input:
Chaix was born in Geneva, but both of his parents were French citizens; he studied at the Conservatoire de Musique de Genève but never became a Swiss national. In 1943 he joined Loys Choquart's Dixie Dandies ensemble, and in 1951 was a sideman for Claude Aubert's band, a group he would eventually become the leader of. He also began recording under his own name in the 1950s, both on solo piano and with ensembles, and worked as a sideman for American expatriates such as Sidney Bechet, Bill Coleman, and Albert Nicholas. He worked frequently as a leader in the 1960s and did many of his own arrangements; Roger Zufferey and Michel Pilet were some of his sideman. He also worked in the 1960s with Milt Buckner, Benny Carter, Buck Clayton, Guy Lafitte, Ray Nance, Rex Stewart, and Ben Webster.

### Response:
Henri Chaix was a talented musician who played the solo piano and with ensembles.
