By the way what does "attacca" mean in a score?
It means that you move straight on to the next section of the music without pausing. It is usually used between movements of a sonata. For instance at the end of the first movement of Beethoven’s Moonlight. It means that you move on to the second movement without batting an eyelid.
The word comes from Italian and it means variously: to attach, to tie (the relevant meanings here), to begin, to attack (not so relevant)
Best wishes,
