Carl (or Karl) Tausig was a Polish virtuoso pianist, arranger and composer. Tausig was considered by some critics to be the greatest of Liszt's pupils, pianistically speaking, and to carry pure virtuosity to heights only suggested by Liszt. Anton Rubinstein called him "the infallible." Where Tausig differed from his teacher was in his lack of flamboyant gestures while playing. Tausig sat motionless at the piano and abhorred what he called Spektakel. While his fingers were working miracles at the keyboard without any digital errors, the only sign of tension from Tausig would be a slight tightening of one corner of his mouth. Until his untimely death, some critics surmise that Tausig may not have had a pianistic equal, combining Liszt's force and range of tone color with the intellectuality of his fellow pupil Hans von Bülow. Another Liszt pupil, Eugen d'Albert, compared Tausig very favorably with their teacher. He said that while Liszt's musical conceptions were grander, Tausig possessed a better and more accurate technique coupled with a good deal of poetry.
