How you use Arpeggios to solo with?

How do you know what Arpeggios to uses?

This isn't an easy question to answer.

The answer goes back to basic music theory and which notes are in which keys. You have to have a working knowledge of the circle of fifths and all the modes.

Do a search at wholenote.com or search the forum here at Guitartricks for an explanation of these.

basicly just try to match them with the chords you are playing, for example if the rhythm guitar is playing
C7, probably the arrpegio of C7 will fit.

I start the song off with it, I rake them instead of singal picking and I play them faster , in solos if I use them in solos, whihc is just about only in classical songs.
