Let me introduce myself, I'm from Florida and I was inspired to play electric due to seeing some great bands live all the notes that play in my head!
Is Smoke on the Water an example of a power chord?

Thanks to schegel and benoit for those explanations! I will read again but is it possible to use different scales together in a song.
I stopped learning songs for awhile to learn only scales until memorized.
I have been playing for a year and lessons for 6 months. I might not go back to the instructor! I have been happy I found these forums!
Is it really that important to use ones ear to learn a favorite song over tablature? I like reading the tab and listening to the song to learn!
Thanks again!
