Practice this tuning-specific layout

Play Bb Phrygian Scale on the low D string at frets 1, 3, 4, 6, 8, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Cb on open string 2 ring, then connect it to the nearest Bb root and two other scale tones.
Connect the Bb root positions on strings 6 through 1 at frets 8, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
