Imagine that in some unspecified future when the secret of time travel has been unlocked, the ancient practice of writing music down has been rediscovered and humanity has learned anew the language of the emotions, and of mathematics, embodied in making music. You have been picked as one of a small team of investigators whose task it will be to insinuate yourself into other times and other situations to retrieve forgotten songs and lost melodies. Your specialist task will be the rediscovery of the songs and tunes that lightened the load, and made shorter the marches of soldiers generations ago.
While the stories told are fictional, they are based on historical facts.
