A little high C in the morn....
Admittedly it is not C5 but B4. (Just one fret/semitone down) Our departed friend Luciano was considered king of the high Cs considered the highest regular note in solo tenor work. Two of the highest notes in the tenor range are sung in this fantastic aria - B4 followed by A4. To put that into perspective, middle C is C3. After Luciano Pavarotti performed "Nessun Dorma" at the 1990 FIFA World Cup in Itally (his recording of the aria was also used as the BBC's theme song for its television coverage), his recording reached #2 on the UK Singles Chart - an event that has never happened for a classical music song. Learn why Pavarotti's performance of "Nessun Dorma" is so special. In the actual score of "Nessun Dorma" Puccini did not sustain the high B4 note at the end of the piece
