In an article by James David Jacobs about Shakespeare and music he writes
"The Tempest stands at the crossroads of theatrical history: between the Renaissance and the Baroque, between the Elizabethan theatre of the imagination and the Jacobean spectacle, between the primacy of the word and the primacy of sensory entertainment".
Similarly The Fairground Booth was written and performed at the threshold of a new epoch in 1906 in Russia.
The common link between these plays is music. It's no coincidence that at the same time these upheavals were taking place in England, the art form known as opera was being born in Italy (the first operatic masterpiece, Monteverdi's L'Orfeo, was premiered in 1607.) And it is not an accident that The Fairground Booth appeared at the junction between two epochs and the beginning of what we understand as the modern era.
