JŠnos started studying violin at the age of 10 at the local conservatory in Miskolc, Hungary, before switching to viola in his late teens. Leaving Hungary for Canada in 1957, he soon continued at the University of Texas, in Austin, where he obtained his B.Mus. and met his wife Jerry. The Csabas moved to Montrťal in 1962, and to Ottawa some years later. JŠnos continued his studies in Rochester, N.Y. (where he obtained a Master of Music in Performance and Literature from the Eastman School of Music) and, with the assistance of the Canada Council, in Sienna, Italy. He and his wife were founding members of the National Arts Centre Orchestra. JŠnos has contributed to the musical life of the National Capital area as a teacher (Canterbury High School and the Conservatoire de Hull), as a conductor of the Intermediate Orchestra of the National Capital String Academy, and as a soloist and chamber music player. A member of the NACO and Thirteen Strings, he served as Principal Violist of l'Orchestre de chambre de Hull (for six years), and the Ottawa Symphony Orchestra (for five years).
