Watch the C# Locrian 3 online guitar lesson by Robbie Calvo from 50 Modal Licks You MUST Know
A simple Idea enhanced by the long descending glissandi from the note A at the 10th fret to the note E at the 5th. The last part of the lick is a 16th note phrase derived from a Bmi7 arpeggio at the 14 fret.
I like how the long sustained notes are then capped off by a 16th note run from the Bmi7 arpeggio. It's a great way to build pace during a solo. Don't give away all of your chops at the beginning,build the melody and save something special for a crescendo!
