MUSICAL TRUMPET. ^ he Musical Trumpet is a wind instrument which sounds % pressing the closed lips to the small end, and forcing the "’md through a very narrow aperture between the lips. T his is one of the most ancient of musical instruments, and has appeared in all nations in a vast variety of forms. The ^nch of the savage, the horn of the cow-herd and of the Postman, the bugle horn, the lituus and tuba of the Romans, *he military trumpet, and the trombone, the cor de chasse or French horn—are all instruments winded in the same man- ner > producing their variety of tones by varying the man- ner and force of blowing. The serpent is another instru ct of the same kind, but producing part of its notes by Cns of holes in the sides. Although the trumpet is the simplest of all musical in- str uments, being nothing but a long tube, narrow at one Q.- l O O o n an d wide at the other, it is the most difficult to be ex- ain«L To understand how sonorous and regulated un- ^ at ioiis can be excited in a tube without any previous vi- j ratlon of reeds to form the waves at the entry, or of holes c| Var ^ ( ^’ e notes, requires a very nice attention to the me- 'anism of aerial undulations, and we are by no means cer- 111 that we have as yet hit on the true explanation. We Cer tain, however, that these aerial undulations do not ^ er from those produced by the vibration of strings; for c ma ke strings resound in the same manner as vibrating s Galileo, however, did not know this argument 3
