DescriptionThis early mechanical movement works on the same principle as the tower carillon, with descending weights, a programmable cylinder or drum and a set of bells for playing the music. There are five gears, each driven by five weights. Quarter past, half past and quarter to are indicated with one, two and three beats by the quarter beat movement. The whole hour is marked by four beats of the quarter striking movement after which the playing movement comes into action. After a complete revolution of the playing drum, at the end of the melody, a pin attached to the side of the drum highlights the hour striking. The playing drum rotates fully in about 30 seconds. Six keys - one for each note - lift up the hammers, after which they fall back under their own weight and strike the corresponding bell.
Accompanying textsSix hammer springs cause the hammers to spring back slightly after each beat, leaving the bells free to resonate properly. The fact that the drum is reprogrammable means that the repertoire could be changed. However, it is unknown whether the music was often changed on this type of instrument. What we do know is that the melody on it today is not original. Due to the small number of bells, only simpler repertoire is possible.
It is hard to imagine today, but around 1550 it really was an amazing phenomenon that you could make music without a musician. After the development of the tower carillon, musical clocks appeared for the living room. Although, of course, such an instrument was not for everyone. Around 1550, musical clocks were mainly found among monks and later also among the well-to-do. Of these earliest European self-playing instruments, monks were also the makers. This example is the oldest piece in the collection of Museum Speelklok.
