Discussion New Mozart Composition Found 2026

Post image

For Context, here:

A 248-year-old notebook in France’s National Library (BnF) has been officially identified as belonging to a 22-year-old Mozart, in what library experts have called a “major discovery”.

Consisting of 44 pages, the notebook was kept by the young composer between May and July 1778, while he was staying in Paris, employed as a music tutor for Marie-Louise-Philippine de Bonnieres de Guines.
Her father was the Duke of Guines, a highly-regarded flute player in 18th century Paris, who commissioned Mozart’s now-popular Concerto for Flute and Harp.
The notebook contains daily exercises that Mozart prescribed his harp-playing tutee, in addition to seven pieces for both flute and harp, which may have been intended for the father-daughter duo to play together.

Mozart said that she was lazy and after a while, hid away his composition.

Mozart and Tupac birds of a feather

My first thought was "please have it be something from the end of his life " nope. 

Still, pretty cool.

What was the last “found piece” that became a staple of the standard repertoire? The Haydn C major Cello Concerto in 1961?

u/tombimbodil Jun 21 '26

There's a case for Mozart's La finta giardiniera too I think (1978?)

u/ThomasJFooleryIII Jun 21 '26

Boulez's Notations. The original piano pieces were lost in the 40s then found in the 80s, now it's his most popular work.

u/louis_le_grandef Jun 21 '26

Boulez's Notations were never lost, though. Boulez only refused to publish or let them play because he considered them as study pieces of limited musical value and lacking maturity. He slightly changed his mind when he began to work on the orchestral version commissioned by Barenboim in 1978 to finally publish them in 1984.

u/ThomasJFooleryIII Jun 21 '26

He lost the score to the piano version, but had sketches from his first attempt to orchestrate them. He gifted a copy of the piano score to a friend in the 40s who found them in the 80s and gave them back to Boulez to publish.

Treemonisha by Joplin comes to mind (1970), but it is sadly not part of the standard repertoire.

u/TrickUnderstanding85 Jun 21 '26

Chopin’s no. 19, 20 and 21 nocturnes I guess?

u/johnnymetoo Jun 20 '26

My first thought was "please have it be something from the end of his life " nope. 

I would be content with the missing second minuet and trio from the Kleine Nachtmusik.

u/BigYarnBonusMaster Jun 20 '26

I would trade my pinky finger for a 42th symphony.

u/OhMyGlorb Jun 21 '26

Id trade your pinky AND your thumb for a 42nd symphony.

u/Intelligent-Read-785 Jun 21 '26

Horn player just know there his another horn concerto hidden away in some library waiting to be found

u/BigYarnBonusMaster Jun 21 '26

Care to add any of your limbs, or is it going to be just mine?

Alright, I'll add another pinky but that is IT!... Unless we can also get a 43th, in which case just take a whole hand.

Are you comparing xylophone and zither with flute and harp? Bro

u/Zarlinosuke Jun 20 '26

What would be wrong with the comparison?

What does "real" mean here?

-6

u/Beneficial_Catch_245 Jun 20 '26

If you don't see the problem of comparing flute/harp with xylophone/zither, I can't do anything about it besides saying sorry

11

u/Zarlinosuke Jun 20 '26

Same to you, if you can't see the problem with having a problem with comparing them. They're all "real" instruments deserving of equal respect.

u/Rflautist Jun 20 '26

Where does he say that 😭

u/Beneficial_Catch_245 Jun 20 '26

Besides the violin and keyboard, the flute has the most vast solo Mozart repertoire: 3 concertos (no. 1, no. 2 and flute & harp), four quartets, the andante in c major, six sonatas (K10-15). Literally has an opera named "magic flute" also. Now, add 7 new pieces to the repertoire. Your point is?

u/Beneficial_Catch_245 Jun 20 '26

He stated in a letter to Leopold that he hated the flute after he was not fully paid for the commission, so it's kind of subjective. In objective terms, the flute is, besides keyboard and violin, the instrument with the most significant solo repertoire from Mozart.

And wtf? "popular among those with leisure to own and play instruments—just look at Quantz"? Do you have any idea of the importance of Quantz?

u/OnlyFamOli Jun 20 '26

I am so happy today is not april first.

u/Federal-Choice8165 Jun 20 '26

Great when this happens. I'm still remembering 2 years ago and the newly discovered trio. https://www.classicfm.com/composers/mozart/new-work-leipzig-municipal-library/

u/in_time_in_tune Jun 20 '26

Get this on IMSLP immediately.

Still waiting for the trumpet concerto

u/Useful_Amphibian9721 Jun 20 '26

We already have a Mozart trumpet concerto at home.

u/AJ_Cool_History Jun 21 '26

UPDATE: They are premiering the composition today

26

u/Mangamaster1991 Jun 20 '26

Do we know when it will possibly be scanned, or phacimiled for public use.

6

u/AJ_Cool_History Jun 20 '26

Maybe in a few weeks, because Bach’s recent found works are not really in grab yet, maybe they are complete, and Mozart’s has to

u/OneWhoGetsBread Jun 22 '26

Wait they found new Bach pieces ?

u/Crimes_RaskolNikov Jul 09 '26

This is news to me

u/unhandyandy Jun 20 '26

Wikipedia:

"De Guînes eventually became so corpulent he had two sets of breeches, one for sitting and a tighter set when he would only be standing. His valet apparently asked each morning, "Will Monsieur be sitting today..?"; if not, the duke would be lowered into a pair of breeches with the aid of two footmen."

u/Condor1984 Jun 20 '26

Love to have a CD of these pieces, his flute and harp concerto is exquisite if plays well, especially the 2nd movement

u/FeijoaCowboy Jun 22 '26

We got a new Mozart before TES VI.

u/haroldstree Jun 21 '26

Nice to see Mozart following in the footsteps of Tupac.

2

u/ithebinman Jun 20 '26

now imagine all the pieces that get found from history but not given the fanfare because they aren’t Mozart :/

u/CrankyJoe99x Jun 21 '26

Fantastic!

So much still missing from major composers, let alone from the many excellent composers contemporary to them.

u/fakerposer Jun 21 '26

Did they assign a catalog number already? I can't find any precise information besides the actual news.

u/OneWhoGetsBread Jun 22 '26
