Answer:
A.
Step-by-step explanation:
Instruments, such as the vielle, harp, psaltery, flute, shawm, bagpipe, and drums were all used during the Middle Ages to accompany dances and singing. Trumpets and horns were used by nobility, and organs, both portative (movable) and positive (stationary), appeared in the larger churches. They were used in pageants and fanfares, as well as in various military contexts, where their bright sound could convey messages across relatively large distances. Also called Buisines, Medieval trumpets tended to be straighter and longer than their modern counterparts.
