lets start with #3
a time signiture
is made up of two numbers.
the top one represents how many beats will be in a measur ( you can have 2, 3,4,8,12)
while the bottom number will tell you what kind of note gets a full beat
if 4 is the bottom note then a quarter note gets a full beat (so everything is normall to what i posted before)
