I am trying to understand the intuition behind the time signature. My confusion is as below :
My first confusion was why in general every metronome beat is considered a quarter beat, but what I realized as I read more, is that usually it's a standard but it's not necessary. I mean it's usually mentioned, (for example) that the tempo is 60 bpm and each beat is a quarter/whole/half beat. Please correct me if I'm wrong here.
Now coming to time signature, Let's say my music is in 4/4 and is 60bpm. That means every beat is a quarter note. From this I understand that my music is going to feel like it's structured in 4 beats or pulses at a time. The pulse is going to feel like 1-2-3-4, 1 having more accent.
Now lets say my music is in 4/2 and is 60bpm. I am unable to understand what difference this change in beat value will bring in my rhythmic feel, because All I can think of, is that if I put that in a metronome, every tick is a half beat now; then there is no difference between what I was playing previously, (for example, 4/4 in point 2), and if I say that the metronome beat is still a quarter beat, then its just going to make my music sound slower.
Please help me in clearing this confusion. Thanks. :)
