Ruphin Coudyzer's hobby is playing the cello.
A lifelong interest in music compelled him to take up the cello in 1984 at the age of 36.
Together with the pianist John Oakley-Smith he played in the theatre production ''Torch Song Trilogy'' at
The Market Theatre in that same year, even though his score was somewhat simplified.
In 1990 he joined ''The Johannesburg Symphony Orchestra'', an amateur ensemble under the leadership
of Pienaar Fourie.
In the beginning of 1994 he became the principal cellist of this orchestra.
Ruphin plays cello on one track of Jennifer Ferguson's second album ''Untimely'' of 1990, for which,
incidentally, he also took the front cover photograph.
He is also a member of a string quartet.
Since the beginning of 2002 he has been taking advanced classes with Peta-Ann Holcroft, principal
cellist of the Johannesburg Philharmonic Orchestra.
In December of that same year he gave his first solo recital (cello and piano).                                      In November 2007 he was the 'lone cellist' in a staged reading of Arthur Miller's play "Broken Glass" at The Actors Centre in Johannesburg directed by Dorothy Ann Gould.
