What is "karantouzeni"

The karantouzeni is a stringed instrument of the lute family resembling the tambouras, although larger and possessing four strings. It is typically used in the " rebetiko" revival movement of Greek folk music, a synthesis of the disparate remnants of urban Byzantine culture that was in many places subsumed by the predominant Turkish culture of the Ottoman Empire. It is usually tuned in the Ntouzeni style, much like the bouzouki, another pre-Ottoman revival instrument associated with the rebetiko movement..
