Practice this tuning-specific layout

Play Ab Locrian Scale on the low C# string at frets 0, 1, 3, 5, 7, 8, and 10, saying each note name and degree aloud.
Build a phrase that lets Db on open string 6 ring, then connect it to the nearest Ab root and two other scale tones.
Connect the Ab root positions on strings 6 through 1 at frets 7, 0, 7, 2, 10, and 5, adding the nearest scale tone between each pair of roots.
