Music as a medium of public entertainment and education arose particularly in the 19th century; and once it also became possible to entertain and educate people with moving pictures (i.e. thanks to the invention of cinematography) around the end of that century, the race was on to yoke music and dialogue to these via a soundtrack for a 'multi-sensory' experience, as achieved in the first 'talkie' in 1928.
Until and beyond that time, there were also theatre and cinema organs which allowed 'orchestral-style' playing of atmospheric music, and were often also equipped with some sound effects on the 'toy counter' of the console: horse-hoofs, bells, sirens, wind and rain noises, bird-whistles and the like. By the technological standards of the day these were clever, remarkable, practical and fun.
The author Aldous Huxley in his Brave New World (1931) goes at least one step better: his 'cinema trip', in the then-near future, is developed into which of these experiences?
The film is in 3D and the soundtrack plays through individual binaural stereo headphones
The music is played through speakers inside the auditorium seats, to provide immediacy to it and anticipating 'sensurround'
The show is called 'the Feelies', with audience members gripping a brass knob on the armrest that allows sensations to be sent direct to their nerves by electric current; and in the interval, an organ-like console ascends onto the stage, but it plays a 'symphony of smells and scents' rather than music for the ears
The music is all-electronic and comes from loudspeakers which move around the auditorium, or else the control system is sophisticated enough to make that seem to be what is happening
