A chime bar or resonator bell [1] is a percussion instrument consisting of a tuned metal bar similar to a glockenspiel bar, with each bar mounted on its own wooden resonator. [ 2 ] [ 3 ] Chime bars are played with mallets again similar to a glockenspiel.
Some towers contain additional bells so that different subsets of the full number can be rung, still to a diatonic scale. [1] For instance, many 12-bell towers have a flat sixth, [2] which if rung instead of the normal number 6 bell allows 2 to 9 to be rung as light diatonic octave; other variations are also possible.

High strikers come in different shapes and sizes. Heights range from 4 to 20 feet (1.2 to 6.1 meters). There are many brands of high strikers commercially available. Most models use a spring-loaded lever that can be adjusted to increase or decrease the force required to propel the puck to hit the bell. Other high strikers are themed in design.
The 6 m × 4 m × 2.5 m bell is accessible through a 2 m diameter tube and an airlock. A pantograph system keeps the bell and internal stairs level at all depths. Maximum working depth is 10 m. The vessel is used on those inland waterways which have locks large enough to accommodate its 52 m length overall, 11.8 m beam and 1.6 m draft. [30] [31]

Barbells range in length from 1.2 metres (4 ft) to above 2.4 metres (8 ft), although bars longer than 2.2 metres (7.2 ft) are used primarily by powerlifters and are not commonplace. The central portion of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon's Axle), and is often engraved with a ...
