The sonic result of this riff gives you an E7 flat 9 #5 sound. You don't have to wait to find this exact chord written on a chart. You can play it over just an E7 to add tension. Altered chords are usually dominant chords with either the 5th or 9th or a combination of both, sharped or flatted. This should be played in the twelvth position. It includes a couple of unison bends from D to E as well as from A to B. Be conscious of the augmented triad arpeggios.
