if found...and still do find timing in the standard latin notation really confusing. But, it's really simple once you get your head round it. A lot of songs use 4/4 timing...simple as hell just count 1-2-3-4.
Older Classical music such as waltzes use 3/4 timing, however PeepHole by System of a down is also written in 3/4 lol.
2/4 you can think of as merely a faster version of 4/4.

any Latin timing Notation can be worked out simple. The first number(top number) is the number of beats in a bar, and the bottom number(last number) is the number of bars in a standard Chorum...which is just a posh name for a line of sheet music.

However the 'Sihluetto' bit in bohemian rhapsody is timed at 7/8...how the hell do you work that one out lol
