I often see this image in VK, OK and Facebook. I can't understand this F#m8b12b#8 chord! I know it's a taunt of a kind but does it really exist and what notes are those and how to play it on Guitar and Keyboard?
OK, as said in my comment, this is a joke and that chord doesn't exist. But here's why:
F#m8doesn't make sense because
8is the octave, so it doesn't add anything to the chord.
b12doesn't exist; the
12is equivalent to the fifth, which is a basic chord tone, so if it should be flat, it should be a
b5; however, this contradicts the F#m chord, which as a perfect fifth; there can only be one fifth; enharmonically, the
b5could be a
#11), so if you wanted to add that note, it should be a
#11). Note, however, that this tension is very uncommon in a minor chord.
b#8is non-sense; is it flat or sharp or none of the two? Whatever it is, it is also non-sense because, as mentioned above,
8is just the octave, and in a chord in doesn't make sense to alter the octave. If you want a chord tone a half step lower than the octave, then it's a major seventh; a half step up from the octave, it would be a
