In conversation a small doubt arose, which none of folks gathered knew a correct answer to, even though I'm guessing it should be common knowledge around here. Here goes:
 
What does the 9/8 on the Apocalypse section of Genesis' Supper's Ready stand for? The most common answer was time signature, but no one was really sure.

Correct.  9 represents nine beats per measure, while the 8 indicates that an eight note counts as one beat.

Hi Kotro

It was, indeed, nine beats to the bar which gave the sub section its unique name.

Also, technically the Apocalypse is poly-rhythmic, at least so long as Tony gets his say Wink

But yes, the majority of the section is in 9/8, hence the title

9/8 is not 9 beats each of an eighth note.

9/8 is compound time. It can be counted as 9 beats each of an eighth, but the true beat value is 3 beats each of a dotted quarter.

If the top number is divisible by 3 but larger than 3 then the time signature is compound. You need to divide the top number by 3 to get the beats. You then divide the bottom number by 2 to get the beat value. This will give you 4 which is a quarter note, then to make a compound note, add a dot to the value to make a dotted quarter as the beat value.

This is important, because 9 eighths notes to a measure produces different stress values to 3 dotted quarters per measure. 3 dotted quarters to a measure actually gives you a waltz stress pattern.

^ but then again 9/8 doesn't always mean 3-3-3 ...

True PF. In the case of the apocolyse section Hackett is doing some nice syncopation on counts 3, 5 and 9 with the high F# in the repeating sixteenth - sixteenth rest - sixteenth - sixteenth rest... chord pattern. Banks' organ would seem to be standard 9/8 over the top of it, giving the organ a nice flowing feel, while the guitar gives it that broken punch. So in this case there is the keyboard using a standard approach to 9/8 and the guitar with the syncopated pattern driving it on.

This is complicating the things, even if it's true (and it is). And it's yielded from someone raised on Western music.Wink

This is true, and its strange that he's opted for the more complex spelling.

Ha! It literally is ignorance, but in your case absolutely forgivable. Presuming of course that you are Portugese.Smile

If you are English though.....

I could be wrong (knowing me I probably am), but I'm pretty sure the riff is in 9/8 but the keyboard solo is in 4/4.

Nah- all instruments are in 9/8 in the apocalypse section. A good percentage of the organ section are just 3 groups of sixteenth notes per measure. It may be the waltz feel (I'm not saying this is straight forward 1 2 3) in the organ over the staccato guitar chords that is confusing the issue.

Just to clarify, 9/8 is only a compound time when phrased that way, example: if the accents are on beat 1 and beat 7. However, if used like in Dream Theater's "Voices", where they simply play a 4/4 beat and add a quaver on the end, it is still technically 9/8 but it isn't compound in the slightest.
