I Don’t Know Guitar Lesson – Ozzy Osbourne

In this "I Don't Know" guitar lesson video, I will show you how to play this great Ozzy classic featuring Randy Rhoads note-for-note.

The opening riff uses a driving sixteenth note feel interspersed with power chords. Try to focus on the accents within those 16th notes, to help you lock into that feel.

The pre-chorus incorporates an intricate lick that can take a little bit of practice, especially at the end of it when you have to double-pick that lick.

I will go through each section of the song in the order that each appears and cover each riff and fill that Randy played.

For the clean section, I will be referencing the live version Randy plays on the "Tribute" album. This seemed to make more sense to me since the original recording uses a bunch of guitar overdubs at that part.

I will also cover Randy's killer solo note-for-note. For the solo, I will be back to referencing the original studio recording.

Have fun learning this early Ozzy classic with the incomparable Randy Rhoads! Carl...

    Hey there,

    It might be just me but I think your link to the youtube page has the wrong link. It takes me to an “edit annotations” page. Thanks for these by the way your generosity does not go unnoticed.

    Awesome !! am I the only one who can’t seem to get this tone right though ?? how about a lesson on this tone also ?

    • Carl Brown on July 15, 2014 at 9:24 am

      Yeah I am working on some tone lessons for the next couple of weeks.

      I try to aim for a tone in my tone lessons that a lot of people recognize but for this particular lesson I just tried to dial in a decent hard rock tone but didn’t really try to match Randy’s specific tone.

      I will definitely being doing some tone lessons on him though. 🙂

    Wow! What a great lesson! The clean section is a beautiful piece of music taught with your normal exacting detail. My favorite part is your deadpan at 34:11… yes, that is an awesome lick. Thanks so much for doing this.

    It looks like the neck of your guitar has been “scooped” or something between the frets as you get further up the neck toward the pickups….whats that about? whats the advantage?
