Watch the Notes Around the Chord online guitar lesson by Jimmy Heffernan from Dobro Handbook
I'm now going to show you all of the major scale notes that are close to the C chord.
When you learn to "see" them without thinking, you'll free your mind up and can then be a lot more musical in your improvisations.
Notice the tone and vibrato I use to "sell" each note in my lines - this will come in time for you as you get more comfortable.
Using just this position, you can play through the changes to any diatonic chord progression, in any key. I play it here in C, but just like guitar, you can move it to any key by just moving the form to a new spot on the neck.
