Marion Harland,
Marion Harland's Complete Etiquette
“ The same rule of promptness applies to a musicale. After greeting the hostess, guests take the seats assigned to them, and chat with those persons near them until the program is begun. During the music not a word should be spoken. If one has no love for music, let consideration for others cause one to be silent. If this is impossible, it is less unkind to send a regret than to attend and by so doing mar others’ enjoyment of a musical feast.At a ball or large dance, one may arrive when [58] one wishes. ”
