This lesson is for power-metal bands.Here you'll see 
what is power-metal and how it is playing.

Before exercise read this:
Power-metal is metal where everything plays fast, but 
with melody. Power-metal is metal where used 
something from middle time music(songs 
about dragons,elves, 
dwarves etc).Main instruments in power-metal are guitar 
and keyboards.In power-metal guitars are usually setted 
by Eb or D; E is rare.


Ex 1 Here is a "simple" power-metal riff.(Speed of Light 
- Stratovarius)

Ex 2 Here you can see how keyboards may be the lead 
instr.(Marsh of Swordmaster - Rhapsody)

Ex 3 The same but with guitar accomp.

Ex 4 Here is an interlude (Children of Bodom - 
Deadnight Warrior (Children of Bodom is not real 
power-metal, but it's melodies are very alike))

Ex 5 This riff is from Destiny (Stratovarius) download it 
(mp3; midi - no matter )you'll see that threre is choir intro 
and 
then guitars are playing the same melody but in faster 
tempo.This also the way of playing power-metal.

For keyboarders: in p.-metal bands keyboarders usually 
use Korg synths because there more instruments.(for 
example in Black Diamond (again Stratovarius) intro is 
playing on instr which I couldn't found on Casio or 
Yamaha synths or Guitar Pro.

P.S.I used tabs  of: ChromatiC (speed of light);
Melkwurt (march of swordmaster)
Juha-Matti Kallinen(deadnight warrior)

Thank you guys.
