There is a moment in the second movement of K. 488 — the Adagio, the only time Mozart ever wrote in F-sharp minor for a concerto — where the piano enters so quietly you check the room to make sure nothing has changed. Everything has changed.
Mozart finished the A major concerto in March of 1786, the same furious season that produced The Marriage of Figaro. He was thirty years old, at the absolute summit of his powers, and writing faster than most people think. The concerto was almost certainly premiered by Mozart himself at one of his subscription academies in Vienna, those rent-paying concerts he organized in rented halls where he would improvise, dazzle, and pass around sign-up sheets afterward.
The Instrumentation Matters Here
He scored it for flute, two clarinets, two bassoons, two horns, and strings — no oboes, no trumpets, no timpani. That’s a deliberate choice, not an oversight. The palette is soft, reedy, autumnal. The clarinets especially carry a warmth that oboes would have sharpened into something more public-facing.
This is private music dressed up in a concert hall.
The first movement is so natural it can fool you into thinking nothing is happening. The themes feel like things you already know, which is precisely Mozart’s trick — he constructs inevitability from scratch. The development section slips into places the opening absolutely promised but never quite announced.
The Adagio
Then there’s the middle movement.
F-sharp minor is a remote key in the 18th century, difficult on keyboard instruments of the period, and Mozart knew it. He used it once, here, and the effect is total isolation. The piano sings an unaccompanied opening phrase that sounds like a question nobody else in the orchestra is equipped to answer. Alfred Brendel once said this movement “makes you feel the soloist has wandered into a room where they don’t belong” — and whether he said exactly that or not, he should have.
For recorded performances, the 1975 Ingrid Haebler / Alceo Galliera reading on Philips has that unhurried, conversational quality that feels right — Haebler never pushed, never decorated unnecessarily. But the recording that actually stops me cold is Murray Perahia’s 1978 recording with the English Chamber Orchestra, engineered at CBS’s 30th Street Studio in New York — that famously resonant converted church on East 30th that captured more great piano recordings than any other room in American history. Producer Paul Myers and engineer Ray Moore kept the piano close enough to feel present without overwhelming the ensemble. Perahia was twenty-nine when he recorded it, essentially Mozart’s own age when he wrote it.
The third movement is delight without apology. A rondo in 6/8, it skips and pivots and drops in a minor-key episode that lasts just long enough to remind you what it cost to get here before sending you back out into the light.
There are recordings that treat this concerto like a monument. The best ones treat it like a conversation that happens to be perfect.
Put it on after the house is quiet. Pour something. Don’t read anything while it plays.
