Wolfgang Amadeus Mozart · 1785 · E♭ major · 890 bars · 1227 chords analysed

The slow introduction is so chromatic that early listeners thought the printed notes must be wrong.

Mozart's 23 quartets include the six he dedicated to Haydn in 1785 — the fruit, he wrote, of “long and laborious effort” — and the three “Prussian” quartets written for a cello-playing king.
