He was born in Chania, Crete, the first son of a refugee family from Asia Minor.
His virtuoso bouzouki-playing made him famous on the popular music stages of Chania.
He went to Athens in the 1960s, where he made his big break into the Greek popular musical scene as a composer.
The song What can you do, with only one heart (Greek: Τί να σου Κάνει μια Καρδιά), with lyrics by Eftichia Papagianopoulou, marked the start of his national career.
Katinaris was married to Maria Rippi, herself a singer and member of a famous musicians family.
