Passaggio, an Italian word translating to passage or transition, is the bane of many a classical singer and the secret weapon of folk-inspired vocalists like Dolores O’Riordan, Jewel, and Sarah McLachlan. In English we often refer to this as “the break.” One of the main goals of classical vocal technique is smoothing out register breaks. This requires finesse, patience, and perseverance. It is a process that cannot be rushed because singing in the passaggio for extended periods of time can mentally and physically tax even experienced singers, causing serious vocal fatigue.
