You may learned it overnight but to solo like Van Halen? In your dreams bro...
You can only understand the soloing concept but far from really understanding the meaning,feel of Improvisation . The note choices the modes the tri tone substitution .
And yes it may seems to be intimidated , but its true to the bone. In order to solo like yngwie malmsteen, you need years of experience on improvisation or learn the top 100 best solo's of all time. But don't give up yet, if they can solo so can you. You only need to start now.
First all you need to do is be able to play the basic of guitar, means playing chords and single notes. Then practice singing what you play, make try to match what you play to what you sing. The. Idea is to sync your mind with the guitars note with your hands or fingers as the bridge.
The idea is simple, if you can't sing what you play. You don't know what you are doing at all.
So try....... and see if you are playing what you can sing..
