Watch the B Ionian 1 online guitar lesson by Robbie Calvo from 50 Modal Licks You MUST Know
B Ionian is, of course, the B major Scale. I'm using the scale to create a melodic phrase that works over the entire B Ionian progression. The best way to start a phrase or lick in my opinion is to outline the first chord with it's chord tones. I used the 5th of the B chord as my entry note in this example and then utilized a repeating motif idea melodically and rhythmically.
You'll notice I skip strings in this lick too. If you find that hard at first, isolate that section and work on it separately until you can play it without mistakes. Then integrate that back into the entire lick.
The ending phrase is an ascending 3rds idea using a B Major triad arpeggio and an E Major triad arpeggio. I suggest using the little finger to start this phrase. The resolution point of this lick is to the D#, the major 3rd of the B chord.
