Glass bead

Glass bead Glassharmonika / Thomas Bloch (2007)

Harmonica - a musical instrument from the group of idiophobic rubies. This is the longest, most often wooden box on four legs, inside which is a co-ordinated several dozen glass plates (also called glass), a set of vibrators varying in size, chromatically tuned. By using a pedal-driven mechanism they are set in a rotary motion. Touching with a wet finger of the rotating lens will cause it to vibrate at a frequency dependent on its size.

The glass harmony was especially well known in Germany and Austria, from which it was brought to Poland in the 18th century. The final form was given to her around 1762 by Benjamin Franklin, who introduced a number of improvements. At the turn of the 18th and 19th centuries it was a popular instrument; Two pieces were also written by Mozart (Adagio and roundabout - KV 617, Adagio in C major KV 356 [617a]). In Poland the famous pianist and composer of the first decades of the 19th century, Francis Lessel (1780-1838), performed the harmonica on glass. Due to the sound of the sound, a legend has arisen around it: it has been attributed to miscarriages of the listeners and to mental disorders. In the later period, the harmony lost popularity.

In Great Improvisation Konrad puts his hands on the stars as on the glass harmonics of circles. Harmonica also used Camille Saint-Saëns in Animal Carnival (Aquarium).
