'Vamp' key/chord is a term invented by a great guitarist from here and it means that the chord/key in which the solo's played over don't move to other keys, but, only on intervals circling that key. Jan's solo is great, but, underneath it, the harmony does not change, same as in 'The Pilgrim'.That’s a great statement…nowadays Maiden.
What do you mean by vamp key?
Im really loving the solo now by the way. Janick articulates every note clearly and it’s jam packed with licks. I count 9. Nice tone. The whole song has a bit of darkness to it and the solo adds to that emotion. Kind of cuts it’s way along the galloping rhythm in Janick’s unique jagged way and I love how Nicko goes heavy on the symbols during the second bar of the solo.
