I don't really see much discussion on this. When people ask about scales, there's plenty of links that pop up concerning fingering, scale charts, books on the subject, etc. But not much about arpeggios. I have a few questions though:
Which ones should be practiced. Naturally, the triadic ones are pretty important (C-E-G-C-etc), but what about those that Chopin uses (they're usually more like melodies, but arps in their execution IMO)? I see so little information on the topic that I figured I would ask for it.
