If I may ask, though.. according to this list the [ symbol may also notate an arpeggio? Is this outdated notation? Or does it just depend on how it is marked on the music? (Do a search on that linked page for the word arpeggio. It should find the right part of the article.)Could anyone clarify that?
There is a BIG different between playing something "slowly" and playing it "fast" , thankfully!
Do you have any tips for what I should be practising, working on, or any sources I could turn to, out of interest? Yup, I'm going off-topic here, so if I should start a new topic for this question. I will.
