Q: What's the difference between 2/4 and 4/4? I know 2/4 is like DAH dah DAH dah... etc and 4/4 is like DAH dah dah dah DAH dah dah dah... etc but you could easily count the ands in 2/4 and have it pretty much the same as 4/4. Sometimes I think maybe a song is in 2/4 but I feel like it could just as easily be in 4/4.
A: in the modern world, 4/4 is the default setting, and usually you would only need 2/4 for a moment if there are really an odd number of 2/4 bars. so if you are in 2/4 but everything happens in an even number of bars, then you'd probably just use 4/4. unless you really want all your bars to appear half the size of what people are used to seeing
