What is a musical cuckoo clock?
Musical cuckoo clocks are regular 1-day and 8-day clocks able to play 2 different musical tunes after the cuckoo sound. Usually the tunes will be played after the half hour cuckoo and after the full hour cuckoo in 1-day cuckoo clocks (MT-clocks). There are 1-day clocks with so called “roof mounted musicals” or “two door” cuckoo clocks, they will play the music only once after the full hour cuckoo (M-clocks). 8-day cuckoo clocks (8MT-clocks) are equipped to play two different tunes as well, but the inner technique only allows them to play the music after the full hour cuckoo. One hour the first tune and the following hour the second tune and the third hour the first tune again and so on.
