Symphony, K. 161 (Mozart)

The first two movements are from the overture to the opera Il sogno di Scipione, K. 126, and the last movement, K. 163, was composed separately.

Köchel gave the entire work the number K. 161 (revised to K. 141a in later editions).

The symphony is scored for two flutes, two oboes, two natural horns in D, two trumpets in D, timpani and strings.

The symphony consists of the following movements: The Alte Mozart-Ausgabe (published 1879–1882) gives the numbering sequence 1–41 for the 41 numbered symphonies.

The unnumbered symphonies (some, including K. 161/141a,[1] published in supplements to the Alte-Mozart Ausgabe until 1910) are sometimes given numbers in the range 42 to 56, even though they were written earlier than Mozart's Symphony No.
