Usually you start learning a scale in a vertical box spanning say the first three to four frets and they indicate what the notes are and maybe the intervals as well. F, E, Em pentatonic, C Major, E Major or what have you.
Here in the exercise number one we immediately start with a full neck pentatonic run on the 2 highest strings B and E starting on the eighth fret but its in 'A' and A is on the 5th fret.
So it takes us from the 5th to the 20th fret. You aren't being groomed to be a blue grass guitarist with this tonality. Which may be exactly what you are looking for. Change can mean growth too.
Now be advised this is all exercises, one after the other and its not rhythm exercise but melodic. If you go this particular route don't forget to practice your rhythm exercises too.
We need both kinds of metronome practice development. I do not recommend this if its you very first foray into guitar. There will be mind numbing repetitiveness and hours before you can play "wild thing". There are no chords here, no strumming.
Brothers and sisters don't forget that if you don't have the equipment to sound like your current teacher's electric guitar with distortion and sustain you are going to wish you did. Some folks suggest a pre-amp and overdrive pedal along with noise suppression to get that metal sound.
Now here is where I am supposed to tell you instructors guitar and amp rig setup. I have no idea. He maybe plays a Jackson or Ibanez Strat shaped guitar and I don't see his amp. Anyway Fender, and Line 6 (recently bought by Yamaha) both sell great cheap solid state amplifiers with lots of bells and whistles that enhance the learning experience. And even tube ones for a little more money so you should checkout their entry range if you need equipment. I have a 75w Line 6 Spider Jam and a 15w Fender Super Champ XD. You can't beat the tube tone of the Fender or its value $350 plus it has a Thai restaurants condiment trays worth of effects built right in. The Line 6 at about 475$ has even more toys: Recording to smart card. tuner, looper, presets and stuff I haven't figured out how to use myself yet! It will give you 4 different metal sounds just by turning a knob with no extra pedals needed.
