virtuoso - genius
A ‘virtuoso' is somebody who excels or demonstrates exceptional ability at something. It was originally used solely in the context of music but has since become much more versatile. The word tends to be used sparingly, though, as such talent or level of performance is not at all common. For that reason, it is considered highly complimentary.
