Feedback and Soloing

[flyin'_fingers]

Feedback:
Yeah I was wondering if there's any way to prevent the feedback, because sometimes when I'm playing and i stop for like a second it's starts screeching and it makes me mad, and i have tried getting far away or turning my back to the amp and still so I would apreciate any advice to get rid of that?
Soloing:
When I improvise, and there's a riff playin on the background, do I have to play the same key as the riff(ex. if an open E chord is played, does the scale that I play has to have E as it's root)?

Yes, you play in the key of the chords. Post in one of the other forums and ask that. Shawn can help you with what keys go with eachother.

One way to solve the feedback problem, is to roll back your guitar volume a bit, just enough so that the feedback doesn't happen, and stand next to your amp facing the same direction as the speaker is projecting. If your amp is pointed to the crowd, stand next to the amp facing the crowd. And try increasing distance from the amp, just stay out of the speakers line of fire. If that makes any sense.

Try a noise suppressor

But i'm kinda confused now, does that means that i have to change the root of the scale everytime the riff changes chords, or can i stay on the same scale?

Ask Shawn (cyberfret) post that in the scales forum or something. But normally with a progression you can stay in the same key with the scales. Sometimes you have to change along with the background parts. It's all in how it all fits together. Shawn can better describe this for you.

i'm sorry if i spoil some theory nazis fun here, but theirs an easy little cheat sheet on www.guitar.ch if your playing pentatonic minor, its root of the key your in. major pent its three frets lower. ionian is at root. for all others that i can tremember, check guitar.ch.

If you have two volume controls, one being the individual channel volume, and the other being master volume, try kturning the channel volume down, while turning the master volume up.
