If so how can it be executed?
the top number is the number of beats in a bar. the bottom number is what kind of note gets the beat. so 5/4 means there's 5 beats in a bar, and a quarter note gets one beat. 3/2 means there's 3 beats in a bar, and a half note gets one beat. if the bottom number is a 3 then i guess you'll have to figure out what 3rd notes are, which i guess you could conclude are triplets, in which case congratulations you now have something that looks exactly like 3/4 except for added fun you have to write the number 3 over every note in the song
