Mae Carwyn wedi teithio'n helaeth trwy Gymru a gorllewin Lloegr yn clera gyda'i delyn pen-glîn. Rhwng 1997-2003, bu'n clera'n llawn amser er mwyn ariannu ei PhD ym Mhrifysgol Caerdydd. Ers hynny, mae wedi troi at fysgio am gyfnodau pan fu mas o waith parhaol, yn 2005 ac wedyn ers mis Ebrill 2010. Carwyn has travelled extensively through Wales and the west of England, busking Welsh traditional folk music with his knee harp. Between 1997-2003, Carwyn was a full-time busker, in order to fund his PhD at Cardiff University. He has subsequently turned to the harp on occasions when he has not been in permanent employment, in 2005 and again since April 2010.
