Keyboard Reflection

I learn some forms of playing the piano/keyboard such as how the start of "Un Sospiro by Liszt" was, the constant hitting of the keys falling and rising. Though I've learnt such types it was challenging to create a tune/piece that fits in with the key that is done. I've always enjoyed playing the piano, it is an extremely expressive instrument and quite complex in several ways. There are two instruments that I would like to learn next, guitar and violin. The guitar is the more probable choice. I enjoy listening to guitar and violin, fortunately, I have a guitar though not used.
