Limited dancing was possible in both the First and Second Class lounges during the evening concerts, if one desired. The usual custom, however, was generally to sit and listen to the music.
A musical selection card was available on these ships (I have a copy) from which the passengers could make requests, including everything from waltzes to ragtime.
Some misconceptions exist about the ship's orchestra. In the First Class lounge was the ship's primary orchestra, led by Wallace Hartley. The other area, however, was served by a smaller trio or quartet more of a Baroque nature.
Afternoon tea time (British Ship---Of Course!) was a favorite diversion predominately of the Ladies.
The Smoking rooms attracted the men. (The Barber Shop and lounges were stocked with 8,000 fine cigars.)
Sadly, it is our modern culture that finds the need for constantly being entertained. The luxury of having nothing to do at every moment was part of the benefit of sailing. Hence, the opportunity to recline in a deck chair on the promenade with a lap blanket and a good book, while waiting for the next steward to come along with a tray of cups filled with tea, coffee, or hot broth.
