On my own reflection about a time signature has two numbers — the top number tells you how many beats are in a measure (grouped together), and the bottom number tells you which note in the music is a beat long. There is no way of knowing for certain what the bottom number is without seeing the music, but musical traditions make it fairly easy to figure out, since composers are not out to necessarily trick the musicians playing the music (although tricking the audience is always cool).
The downbeat of a piece of music is always “1”. It isn’t necessarily the loudest sound, but it feels the strongest. Count the beat (the pulses) until you get to the next really strong beat. That is the top number - the grouping of beats into measures.
Duple meter is music in 2 = Strong, weak. Think marches.
Triple meter is music in 3 = Strong, weak, weak. Think waltz.
Other meters are combinations:
4 is two duples = Really strong, weak, kind of strong, weak. Music in 4 is the most common, because the alternating strong and weak beats make it easy to move to. Think almost any pop song you have ever heard. OK, at least 85%.
5 is a duple and a triple, or the opposite= either Really Strong , weak, kind of strong strong weak, weak, or Strong, weak, weak, kind of strong, weak. Listen to Dave Brubeck - Take 5.
6 can be two triples, or three duples= either Really Strong, weak, weak, kind of strong, weak, weak (this would usually be 6/8), or Really Strong, weak, kind of strong, weak, kind of strong, weak (this is usually 6/4).
Other combinations can get you to even higher numbers, but those are more unusual, so they are not used very often
Please rate my answer if its pass on your expectations thanks
