Picture this: we're sitting at the piano, working through Johann Christian Bach's Op. 15 duets, when something strikes us. This music represents an extraordinary business story from the 18th century.

Here's "The London Bach"—music master to Queen Charlotte herself—lending royal authority to what had been, just twelve months earlier, a quirky experiment in Charles Burney's workshop. As our hands navigate those elegant galant phrases (carefully avoiding collision), we're reminded that this wasn't simply artistic evolution. This was commerce and art intersecting in remarkable ways.

The speed of this transformation remains striking. In 1777, Burney had to finance his own publication. By 1778, Johann Christian Bach—with his impressive royal connections—was already in the game. One year. That rapid entry tells us everything about how quickly publishers recognized the commercial potential.

Vienna's response was particularly enthusiastic. Artaria & Company expanded into music publishing by 1778 with a brilliant strategy: high-quality copper engraving, international distribution, and they specifically targeted the emerging middle class rather than just aristocratic patrons. They published both original four-hand works and arrangements of symphonies and operas for domestic use. Suddenly, you didn't need to attend the opera house to experience Mozart's latest work. A piano and a willing partner would suffice.

By 1782—merely five years after Burney's experiment—even smaller German cities like Dessau were publishing four-hand music. When publishers in regional markets invest capital in a new genre, it signals something beyond a passing trend.

The timeline is remarkable:

1777: Burney self-publishes his "Four Sonatas or Duets" in London
1778: J.C. Bach publishes Op. 15 with royal endorsement
1780: Clementi publishes his pedagogical Op. 3
1785: Koželuch elevates four-hands to concert status
1790s: Four-hand arrangements become industry standard

Within fifteen years, four-hand music went from Burney's experimental self-publication to an essential part of every publisher's catalog. That's not organic growth—that's a gold rush.

As we research this repertoire for our podcast series, we're discovering that beneath the commercial success lies something profound: the recognition that making music together creates connections impossible in solo performance. The four-hand piano gold rush of 1777-1790 wasn't just about money—it was about discovering a new way for people to connect through music.
