Practice this tuning-specific layout

Play Bb Major 9 Arpeggio on the low G string at frets 2, 3, 5, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest Bb root and two other arpeggio tones.
Connect the Bb root positions on strings 7 through 1 at frets 3, 8, 3, 10, 5, 1, and 8, adding the nearest arpeggio tone between each pair of roots.
