A “basso profondo” is an especially low bass voice. While a typical bass can hit E2 (the second E below Middle C), Kurt Moll (April 11, 1938-March 5, 2017) could drop his voice to a Low C, two full steps lower. (This is what it sounds like on a piano.)
The boorish Baron Ochs from Richard Strauss’ Der Rosenkavalier is a role that calls for its singer to hit Low C., and Moll performed it frequently. He made seven complete recordings as Ochs, including a 1984 album with Herbert von Karajan, which Moll was particularly fond of. Through the 1960s, he performed with various German companies and became a regular on European and U.S. stages in the 1970s.
“…an exceptional basso profondo that proved as remarkable for its easy production as for its velvet timbre.” – Opera News
