So as I've been writing a song, I've noticed that the feel is an unaccented one the a heavy accented TWO pattern. So obviously the song was either in 2/4 or 2/2. At first I though 2/4 but it felt different, like more heavier which is how songs with cut time sound, I think, I might have that wrong. Anyway it has the same time signature as the bridge in this song at 2:18 except it's just a tad slower.

But my song has a very heavy one TWO one TWO pattern.
Is it 2/4 or 2/2. I think it's 2/2 but I could be wrong.
Then it goes to 4/4 which just doubles the time of the 2/2 or 2/4 part.
Can someone on here give me some examples AND ideas on how 2/2 and 2/4 sound and feel different?

Not only this, but I've heard that you can feel a time sig by counting ONE - two - ONE two or ONE two Three four but what about the bottom number? Can you feel a difference between a 4, 8, 2, 1 or 16 denominator? Can a whole note even get the beat? I'm curious.

At the 2:18 bridge of the link you posted, it is still in 4/4. What changes is the drum-pattern, which goes into a half-time feel.

So, instead of this (which happens during most of the song):

This is what the out-line of the drum pattern changes to at 2:18:

So what you're hearing isn't how the time signature effects you, but rather just what beats are 'accented' or 'dragged-out' (at least in this song example).

In the first pattern you can see that 1 and 3 are strong, with 2 and 4 acting weaker than they are (even thought 2 and 4 are extremely important in rock music, technically they aren't as "strong" as 1 and 3, hence the bass drum).

In the second pattern, we see that what has basically happened is that the first pattern has been "stretched-out" to make the duration of 1-bar into 2-bars (that's where I get the term "half-time" from).

This is a very classic and idiomatic use of this kind of technique, and you hear it used in a lot of rock music especially in the bridges or introductions of songs.

Now, for your original (or second?) question. The bottom number of the time signature doesn't almost mean a different feel. It kind of depends on who the composer is, however there is definitely a bigger feeling of space when comparing 2/2 to 2/4. Since 2/4 only has two quarter-notes in a measure, the measure "happens" fairly quickly, would you agree? However, in 2/2, an entire half-note gets the beat, and the piece would have more space and a longer sense of direction, yes?

Anyway, talking about the feel of time signatures and rhythm in general is difficult to do only using words, especially written out words. I only wish I could talk to you in person using a drum set or something! Hope this helps.

Then it's 2/2 because it does feel longer and slower. I know what you said about the song might be true I still transcribed it as 2/2 so the player would feel the change more effectively. Thanks
