Classical music
In general, musical instruments have become louder as concert halls have become bigger. Violins are louder than viols. Modern violins are louder than the early 17th century violins, largely because of they have metal strings instead of gut strings. The piano developed from the clavichord which was very quiet indeed. Woodwind instruments developed from Renaissance instruments, while the clarinet was invented in the middle of the 18th century, and the saxophone and tuba came even later. Modern trumpets sound much brighter than the straight trumpets of the 18th century.
