When to use it

Major and major 7 chords, the I chord. Keep the shape and play from each degree in turn. Starting on the 2 gives you Dorian, on the 5 Mixolydian.

How to practise it

Start with the metronome at 60 BPM in 8th notes, ascending and descending, until you can play it without looking. Raise the tempo 5 BPM at a time with the speed builder, then switch on memory mode so the tab hides after the first loop. Earn bronze for playing it through, silver at 4 notes a second, and gold at that speed from memory.
