Musical exhibits. Bloomfield science museum Jerusalem.

The giant wheel. 2.5 meters in diameter, comprises 63 aluminum pipes of various lengths, which play a Bach chorale. Played freely by striking the pipes and turning the wheel. It demonstrates the connection between the size of a tube, the musical sound it produces, and the meaning of rhythm.

A circular xylophone. With 180 keys of various lengths. The ball rolls down the slide from the shortest key to the longest, producing a chromatic sound along the way.

A keyboard. with 15 keys produces two octaves; at the back are hammers that operate much like the hammers of a piano. These set-in-motion wooden pendulums gently strike a set of sound pipes.

A slope. It consists of 30-tone groups that produce a Joy melody. Two balls, released along two different paths, make the same piece, one starting slightly after the other. 

A crank. Turning the handle at the side of the structure, it Controls the operation of nine pistons connected to a medium-sized soprano recorder. It produces an ascending and descending sound using the recorder’s nine tones. The speed determines the tempo of the music.

The harp. A range of two octaves containing all the chromatic notes of the scale, playing by plucking the rubber strings or striking the pipes directly with a stick. Demonstrates the connection between a pipe’s length and the tone register it produces.

Recorders wheel. Twelve large altos operated by a unique set of pistons; gravity caused a weight mechanism to push air and play different tunes.

Sitar house. A pyramidal structure built out of triangularly arranged resonating chambers. It is possible to enter and be surrounded by the sounds it produces. One side of the house is tuned chromatically to produce Eastern-style sounds. The other side, which consists of three centrally joined groups of strings, has a wave-like sound made by piano strings and screws.

Transmission. A structure of random chord sounds. The speed of the handles determines the rhythm, creating polyphony. Possible to operate the exhibit simultaneously with several users.

Giant slide. A 14.5-meter structure consisting of 120 tubes of various lengths and 80 spaces. When a ball slides down, it strikes the tubes and plays Mozart’s Turkish March.

Percussion Wheel. Different  instruments are attached to the 12 sides of this polygonal structure. As the wheel turns, the devices begin to play in an entertaining musical ensemble.
