Symphonious

The symphonious sound of fifty skilled musicians filled the concert hall.

Sleep during this interval was out of the question: […] the songs of Hoel and Cyveilioc, to ring to the profaner but more lively modulation of Voulez vous danser, Mademoiselle? [Do you want to dance, miss?] in conjunction with the symphonious scraping of fiddles, the tinkling of triangles, and the beating of tambourines.
