I was wondering the other day about Paganini and his music. Usually, I think of the 24 caprices or concertos he has composed, but I've heard there are some much shorter showpieces out there for the violin and was wondering if you knew any of them.
You can look up his works on IMSLP and see for yourself.
Not everything Paganini composed is a showpiece. His "Cantabile" is a romantic piece accessible at a reasonably intermediate level.
One that comes to mind is "Witches Dance," from which the famous Suzuki book 2 piece was extracted.
You might be able to do some variations from The Carnival of Venice
The Paganini "Cantabile" is maybe a notch harder than "Meditation from Thais" because of the two cadenza-like runs. The rest of it is easier technically than Meditation. Meditation, in my opinion, is a more artfully composed piece with a more interesting melody.
Here is a few Paganini pieces that I can think of off the top of my head: Moses Fantasy, Variations on a theme by Joseph Weigl, Variations on God Save the King, Variations on Nel cor piu non mi sento, Variations on Barucaba, Variations on Non piu mesta, Variations on Carnival of Venice...
