When to use it

Major 7 chords, especially the IV chord of a major key. With the drone on, land on the ♯4 and hold it. Hear how it hangs instead of resolving.

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.
