On 8 May 1736 London’s Weekly advertiser reported on an exhibition of a musical clock to the Queen, giving “uncommon satisfaction to all the Royal Family present”. Although two descriptions survive, the machine itself is lost.
However, the discovery among Händel’s MSS of two sets of tunes for musical clock suggest that the composer was, at the very least, intrigued by the instrument’s capabilities—it is also possible that this machine, or one like it, played these very works. Clearly Händel was not averse to mechanical reproduction of his works, and he may indeed have heard it happen!
This according to “Handel’s clock music” by William Barclay Squire (The musical quarterly V/4 [October 1919]) pp. 538–552.
