Today's guitar lick is composed of notes from the Neapolitan Minor Scale in the Key of A. The notes of the scale are: A, A#, C, D, F, F,G A.
Note that this is very similar to the A Minor scale with the exception that the B note is now and A#/Bflat.
I was going for a neo-classical sounding lick in the example. I hope you enjoy it. The guitar is tuned down a half step. Note the different rhythmic groupings in the tab.
Cheers.
