Time signatures- Bars in 2, 3 and 4 beats

In this video we're going to talk exclusively about the bar and how we use the most common bars which are in 2 beats, 3 beats and 4 beats. So for example, listen to this music. Now, that one is in 3 beats because we have that 1-2-3, 1-2-3, 1-2-3, 1-2-3, 1-2-3, 1-2-3, 1-2-3, 1-2-3, 1-2-3. And we also have, or this other one. That's in 1-2, 1-2, 1-2. Because we always have that feeling of 1-2, 1-2, 1-2, 1-2. And then there's the biggest one which is 4-1. Remember when we were doing it with the tennis balls? You were rolling one ball, 1-2-3-4, 1-2-3-4. If you do 1-2-3, 1-2-3, 1-2, 1-2. Now imagine that you were covering the same space. Now look at the speed of the ball, 1-2-3-4, 1-2-3-4, 1-2-3. Or in 3, 1-2-3, 1-2-3, 1-2. Or in 2, 1-2, 1-2, 1-2. And then let me change back to 4, 1-2-3-4. So you see the speed of the ball has to be way slower if I'm going to cover the same space in 4 beats than if I cover them in 2 beats. Or I can just go 1-2, well, kind of like this. Check it out. Now if I'm over here using this part of the space, then I can go 1-2-3-4, 1-2-3-4, 1-2-3-4, and I'm here in a complete circle. And I only did 3 cycles of 1-2-3-4, 1-2-3-4, 1-2-3-4. Now if I do in 3, 1-2-3, 1-2-3, 1-2-3, 1-2-3. Roughly, I needed to do 4 instead of only 3. Now let's see with 2, what happens? 1-2, 1-2, 1-2, 1-2, 1-2, 1-2, 1-2. I mean, it's not an exact science, but it shows you that I can cover so much more space with the 4 beat bar. But that also means that it's way bigger. So I need to do those movements when I'm doing 1-2-3-4, 1-2-3-4, 1-2-3-4, 1-2, it's a little bit quicker. Which is what was happening when you were doing it with the ball. Because when you were doing it in 4 beats, you could do, I mean there were even some people that were like twirling it around and it went like 1-2-3-4, 1-2-3-4. But it was only 1-2, 1-2, you didn't have time. So it was just like 1-2, 1-2, 1-2, 1-2. Very fast, with a lot of energy. So we use more energy. It's actually all about what kind of energy we need in the amount of space that we have and in how much time we're doing it. So we're actually studying the relationship between time, space, and energy. Now let's look at it in a little more fine context. For example, like this. If I go 1-2-3-4, never mind what they say on these. Just 1-2-3-4, 1-2-3-4, 1-2-3-4, this is a 4 beat bar. 1-2-3-4, 1-2-3-4, if I take 1 it's 1-2-3, 1-2-3, 1-2-3, 1-2-3, take away this one. 1-2, 1-2, 1-2, 1-2. So I can do, if I have a 4, 3, or 2. Don't mind what they say, that's for another game. 1-2-3-4, 1-2-3-4, 1-2-3, 1-2-3, 1-2, 1-2, 1-2-3, 1-2-3-4, 1-2-3-4, and... Yeah, alright. So that's the difference between bars in 4 beats, bars in 3 beats, and bars in 2 beats. So I hope this helps you to get a better sense of it.
