Paganini, 6 Sonatas, op.3

[steltz]

This may seem like an elementary question to someone who knows the Paganini works, but on this work page, there is an excerpt (or arrangement) of a sonata (presumably) from this set entitled "Sonata no. 12".

How can you have a twelfth sonata in a set of six? Or am I mathematically challenged (I am an orchestral musician, so 12 bars rest = 2 hands and 2 fingers . . . .)?

Does the single sonata belong here?

Well quite often works are numbered independantly of the ones within the opus numbers -- look at Beethoven's sonatas, Op. 27 has both 13 and 14, just as a for instance.
In the case of Paganini's Op. 3, it's possible someone is counting from Op. 2 and 3, both of which are six sonatas for violin and guitar in each, though he wrote a good 30+ more than that without Op. numbers/
