Northern lights chord

In music, the 'northern lights' chord is an eleven-note chord from Ernst Krenek's Cantata for Wartime (1943), that represents the Northern Lights. Krenek's student Robert Erickson cited the chord as an example of a texture arranged so as to "closely approach the single-object status of fused-ensemble timbres, for example, the beautiful 'northern lights'...chord, in a very interesting distribution of pitches, produces a fused sound supported by a suspended cymbal roll".^[1] "The 'northern lights' sounds, so icy and impersonal and menacing, are a brilliant orchestral invention."^[2]

At eleven notes the chord is one pitch shy of the total chromatic. Every note except E is sounded.
