The liveliness and cheerfulness of a carillon is created by the striking tones (nominals) of the individual bells in relation to each other. Carillon bells are usually mounted on beams (the bells do not swing) and are struck by a magnetic hammer. Like a piano, the number of bells of a carillon also determines the number of main notes that can be played (comparable to the number of keys on a piano). Depending on the number of bells, different numbers of melodies can be played and depending on the budget and available space, several octaves can be played with bells.
The larger and heavier a bell, the lower its striking tone. A bell with the striking tone a/3 (1760 Hz) weighs approx. 21 kg and sounds higher than a bell with the tone a/2 (880 Hz) and approx. 67 kg or with the tone a/1 (440 Hz) and approx. 435 kg.
A carillon can be played with a keyboard and various melodies can be stored in the carillon-computer for playback. The carillon-computer, which is easy to operate using a touchscreen or cell phone, can be used to play numerous melodies spontaneously by "click or press ok" or pre-programmed for the weekly or annual cycle.
