A five-bell peal, in workshop ready for delivery. Largest bell = E (1200 mm, 1050 kg)

This peal was installed in 2001 in an Australian cathedral, and is the heaviest and deepest-toned of its kind (a "European peal") in the country.
A European peal is a peal of cast-bronze bells of a type whose historical origins can be found in 13th century Europe. The bells swing back and forth, each at its own rate, and the motifs, or note selections, often in pentatonic scale, follow traditional chants. This peal has the motif "Salve Regina", with the notes

E - G# - B - c# - e

The lowest four notes provide the signature motif, and the fifth bell, e, mirrors, one octave higher, the basis bell E and rounds out the musical impression. The peal is described technically as an harmonic-melodic peal, whose function is to create a "sea of sound" with an interplay of melody and harmony, dissonance and resolution ever changing.

The bells themselves came from the French bellfoundry Paccard Fonderie de Cloches et Carillons, near Annecy (founded 1796), to specification by Hervey Bagot. All the supporting frames, fittings, and accessory parts were designed, constructed, and assembled at the Adelaide workshop of Bagot Bell.

The bells in the five-bell peal are controlled by electrical means--(left) electric bellringer motor and chain drive; (right) largest bell also has an electromagnetic chiming hammer for angelus ring, elevation, and funeral toll.
The electric bellringer motors, electromagnetic chiming hammers, and microprocessor-based control units used by the Bagot Bell business (currently Apollo II, shown, and Tempora; earlier Apollo, Cariomat 2000, Angelus II, Chronoquartz, and Horomat) are sourced from Clock-o-Matic, Holsbeek, Belgium.
