Inside Chamber Music with Bruce Adolphe: Mozart's Quintet in C minor, K. 406 

Mozart originally wrote this as a wind serenade, true, but not for 6 instruments! It is scored for 8 players, 2 each of oboes, clarinets, bassoons and horns.

Is it just me or is there a fire alarm going off somewhere in the distance?

One thing I am curious about with regards to this performance: why do they omit the trills after the falling half-note figure in bars 14, 16, etc, replacing them with just a simple turn? Mozart very clearly writes "tr" in the autograph of the wind version, and the NMA editors saw no reason to change it. The Henle editors saw no reason to comment, if they changed it (and they usually do when they disagree with the NMA). I've never heard another performance by winds or strings that did this.

the only thing that needs explaining is why this music needs explaining
