Roitman (1884 - 1943) had a most beautiful, lyric tenor voice. It was very flexible, and he was able to sing the most complicated coloratura (i.e. the long, flowery, twiddly bits). He was renowned for having the unusual facility of being able to pass from a very high falsetto into full voice with absolutely no discernable break. This is technically very difficult to execute and few, of even the world's greatest male singers, have ever been able to achieve it as faultlessly as Roitman.
