Some popular genres include dimotiko tragoudi (folk music), kantada (music from Kefalonia island featuring male chorus), and nisiotika (music varying between Greek islands). Common instruments are the lira, laouto, guitar, and clarinet. Famous Greek musicians who helped establish traditional styles include Chronis Aidonidis, Manolis Kalomiris, and Mikis Theodorakis.
