I've got a question here, that I'm hoping someone can answer.

Is there any real difference between improvising over Chords, Riffs and Arpeggios? I know that Arpeggios are just chords that have been broken down so you play one note in it at a time, but the technical stuff regarding how to improvise over them confuses me, as well as improvising over a Riff.

For arpeggios, I'm guessing you would just target any of the Chord Tones the moment the Arpeggio begins, but I'm not sure at all...

For Riffs, I'm guessing it's all just about using the same scale the Riff does, but again, I'm not sure. If someone could help me out, that would be lovely. I'm been coming up with a couple of cool riffs lately, so I'd like to know how to go about improvising over them.
