Watch the Fall Down online guitar lesson by Jennifer Batten from 50 Ultra Intervallic Guitar Licks You Must Know
I play a 1,3,6 shape to begin, and repeat it a half step higher, which gives you a flat 9. Then there's an E major triad arpeggio followed by an F major flat 5 triad. At the end I bend the flat 7th degree up a minor third to a flat 9 and finally re-bend the same note a whole step resolving on the root. This riff gives you b9 and #5 alterations when played over an E7 chord.
