Identify the number of 11 Beethoven piano sonatas

Question

I pursue a hobby called "geocaching". Currently, I am trying to solve a puzzle which requires that I identify the sonata number of 11 of Beethoven's piano sonatas, from sheet music (see attached image). As I am a neophyte when it comes to reading sheet music I'd be most appreciative if someone might be able to assist.

Upon further scrutiny, there are several sonatas which appear twice. That would mean the solution has numbers in it that repeat.

Thanks in advance.

Answer 1

It's unclear if you're looking for the opus numbers or the numbering from 1 to 32, so I'll offer both.

In order:

• 4 (Op. 7)

• 9 (Op. 14, No. 1)

• 15 (Op. 28)

• 9 (Op. 14, No. 1)

• 8 (Op. 13)

• 5 (Op. 10, No. 1)

• 1 (Op. 2, No. 1)

• 2 (Op. 2, No. 2)

• 30 (Op. 109)

• 4 (Op. 7)

• 22 (Op. 54)

The images in your post are from the two volumes of the Beethoven Piano Sonatas edited by Heinrich Schenker; you can see the table of contents for the two volumes here and here.
