Beethoven's Opus 7 "Grande Sonata" was composed in 1796-97.
Pianist Andras Schiff has hailed the second movement as one of the greatest slow movements in all of music. Marked largo, con gran espressione, the score includes dramatic long moments of silence between phrases. It is a challenging piece to weave together and play effectively.
I remember hearing the rain pound on the roof above the stage as I was playing this movement in my Masters recital 51 years ago. grin The photos in the video of excerpts from the score are taken from the first edition of the sonata published in Vienna in October, 1797.
