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.

gollark: In the hypothetical scenario in which I had backdoors, I could theoretically just make it accept itself as valid if it was signed by potatOS keys and not your own.
gollark: It still can't verify itself.
gollark: In any case, I can neither confirm nor deny that there wouldn't be much stopping me from just sending backdoored copies into your signing process.
gollark: Well, the program can't usefully verify *itself*.
gollark: I see.
