What is 'Goodbye friend' when translated from English to Italian?

Addio, fratello! for long or permanent separations, Arrivederci, fratello! for opportunities of seeing each other again, and Ciao, fratello! with regular contact are Italian equivalents of the English phrase "Goodbye, brother!" The choice depends upon the frequency (in the second and third cases) or infrequency (in the first example) of interactions between listener and speaker. The respective pronunciations will be "ad-DEE-o fra-TEL-lo," "ar-REE-vey-DER-tchee fra-TEL-lo," and tchow fra-TEL-lo" in Italian.
