Is this flute concerto a long-lost Mozart composition? (Probably not.)

Last week, my news feeds were full of stories about musical manuscripts and rediscovered compositions:

1. On November 27, A manuscript of Mahler’s second symphony auctioned at Sotheby’s set a record for the highest sale price of a musical manuscript.
2. At the same auction, a manuscript of a Beethoven piece failed to sell, and Sotheby’s blames a musicologist for voicing doubts that it’s in Beethoven’s handwriting. 
3. On December 2, Austria’s Tutti Mozart Orchestra premiered a long-lost flute concerto purported to be by Mozart.
4. Coincidentally, that same day saw the revival of Stravinsky’s “Funeral Song,” which was lost in the Russian Revolution and recovered in 2015.

Since this blog’s primary purpose is to debunk musical myths, I’m going to focus on event #3: Is this a lost concerto by Mozart? The answer, unfortunately, is: It’s VERY unlikely.

How "forgotten" was Bach?

Today, I'm getting back to one of the original goals of this blog: debunking myths about composers that have been repeated so many times that they're accepted as truth. This particular myth has resurfaced because Sotheby's recently auctioned the original publishing contract for J.S. Bach's St. Matthew Passion, the work that rekindled interest in Bach's music when Felix Mendelssohn performed it in 1829, over a century after it was written. Or, as our friends at Classic FM put it, "Bach would’ve been completely forgotten by history without this document."

The myth is that Bach's music had been forgotten until Mendelssohn resurrected him. You'll find it in biographic profiles and lists of interesting facts. It's an appealing tidbit because it seems so contrary to our perception of Bach today. Bach is one of the few classical composers that most people have even heard of; even if they can't name him, people can at least recognize a few bars of his work. Whenever we see a television character appreciating some Bach, we know we're meant to understand that their brain is processing information at a higher level, thanks to popular culture linking Bach's music to depictions of genius (a phenomenon that started in the twentieth century, as studied by my friend Kristi Brown-Montesano). Since Bach is ubiquitous nowadays, it would be easy to assume that it’s always been that way. Finding out that it was the exact opposite way for decades after his death is pleasantly surprising, in that it's something you can say to impress people at parties.

Like most myths, this one is based on a kernel of truth. Bach was not famous in his own time, certainly not an international superstar like Handel. Mendelssohn did organize a performance of the St. Matthew Passion, and that concert did much to popularize Bach. But it would be inaccurate to call Bach "forgotten" up to 1829, and Mendelssohn is not solely responsible for launching Bach's posthumous career. Though the myth of Mendelssohn "discovering" Bach might lead one to imagine him as a musical Indiana Jones stumbling across a dusty manuscript, eyes widening as he gradually realizes its brilliance, that just wasn't the case.
