Practice this tuning-specific layout

Play Bb Locrian Scale on the low C# string at frets 0, 2, 3, 5, 7, 9, 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 Bb root and two other scale tones.
Connect the Bb root positions on strings 6 through 1 at frets 9, 2, 9, 4, 0, and 7, adding the nearest scale tone between each pair of roots.
