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?

enter image description here

    It is non-sense, this chord doesn't exist.

    Be interested to hear what it translates to, but sadly, don't think it's playable on this planet.

    Note: the keyboardist on this picture is Jordan Rudess, who is mostly known for being the keyboardist of Dream Theater, a progressive metal band. This picture is just a meme reference to Jordan Rudess' tendency to play complicated songs.

    It's a really very basic chord. Jordan can play it with his eyes closed! Feb 2 '17 at 17:25

OK, as said in my comment, this is a joke and that chord doesn't exist. But here's why:

  1. F#m8 doesn't make sense because 8 is the octave, so it doesn't add anything to the chord.
  2. b12 doesn't exist; the 12 is 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 b5 could be a #4 (#11), so if you wanted to add that note, it should be a #4 (#11). Note, however, that this tension is very uncommon in a minor chord.
  3. b#8 is non-sense; is it flat or sharp or none of the two? Whatever it is, it is also non-sense because, as mentioned above, 8 is 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 b9;

    In it just a funny way to write F#m? scales-chords.com/chord/F%23m8b12b%238 (I don't know how accurate is this tool)

  • It's not F#m, as he said there is a flat 5th (or a sharp 4th)...

    Honestly, it's probably just an F# diminished triad which is a very basic chord. This naming scheme reminds me of any Chord Identifiers on DAWs which tent to just be garbage and only approach chords from the add/no angle once it finds a small set of notes it matches to a known chord.

  • @teodozjan why is there a flat 8? Feb 2 '17 at 17:22
  • @SovereignSun I don't know I just found this tool. I'm not good at at chord theory

It contains F#, A, C#, F#, F#, C

  • Can you explain which pitch is the "b#8" and why?

  • Cb# = C because # means sharp and b means flat

  • And which one is the "b12"?
    – Richard
    Nov 22 '18 at 19:36
  • b12 is a Gb, 12 means 5

  • Sharps and flats don't cancel out each other.
