Blind octave

In music, a blind octave is the alternate doubling above and below a successive scale or trill notes: "the passage being played...alternately in the higher and lower octave."[1] According to Grove's Dictionary of Music and Musicians, the device is not to be introduced into the works of "older composers," (presumably those preceding Liszt).[2]

Blind octave passage on C major scale followed regular two octave passage (with blind octave notes in red).

Alternately, a blind octave may occur "in a rapid octave passage when one note of each alternate octave is omitted."[3] The effect is to simulate octave doubling using a solo instrument.
