I’d choose the concert at which Beethoven’s 5th Symphony was premiered. The full program for the evening was as follows:

First Half

Symphony No. 6 in F major (Pastoral), Op. 68

Aria: "Ah! perfido", Op. 65 (for soprano and orchestra)

Gloria movement from the Mass in C major, Op. 86

Piano Concerto No. 4 in G major, Op. 58 (performed by Beethoven as soloist)

Second Half

Symphony No. 5 in C minor, Op. 67

Sanctus and Benedictus movements from the Mass in C major, Op. 86

Solo piano improvisation by Beethoven

Choral Fantasy, Op. 80 (finishing the evening with choir, vocal soloists, piano, and orchestra)

I simply would like to have been present when the most recognizable piece of music ever written first hit the public’s ears, as well as have the chance to see the man himself performing at the top of his game.
