Born in Prague, Czech Republic, in the 1980s he lived in Australia, where he built his Glass Harp.

Alexander Zoltán - Glass harp

The glasses are tuned directly in front of the audience's eyes. Alexander runs his fingers around the glass rims, while adding or draining water by his other hand with a dipper. Thus the glass tone gets to its proper pitch by a glissando.

Each glass stands for one tone, similarly to organ keys. The sound of the instrument resembles that of a Pan flute, or an organ. The instrument has its own built in amplifier, almost indistinguishable to the audience.

Alexander's repertoire ranges from popular Bach, Beethoven and Mozart pieces to melodies of A. L. Webber's musicals, and rock songs of the Beatles and Led Zeppelin.

For children his repertoir includes several English and internationally known children's songs. For Christmas shows he also has international and Czech Christmas carols in his repertoire.

Alexander recorded 2 CDs, he played in Australian, Japanese, Czech, German, Polish and Dutch TV, at festivals in Europe, Australia, the USA and Canada, also in the Sydney Opera House and the Great Theatre in Calgary - Canada.

He speaks to his audiences in English, Spanish, German and Czech.

His 22 tuned goblets entertain all age groups as well as very demanding audiences. People will speak about his production for a long time afterwards.


GLASS HARP appeared around 1730 in South Germany. By the middle of the 18th century it was fashionable, throughout Europe, and was used in contemporary music. Even Mozart wrote pieces for Glass Harp. 1762 in London, Benjamin Franklin improved the Glass Harp into more sophisticated Glass Harmonica. This instrument is a revived Glass Harp, the first in the world with electric amplification.
