Ableton Forum

Hi,
I'm just a newbie on ableton live, i've bought live 10 suite to teach myself music production.
I'm following a Udemy tutorial and now i'm on Quantising lesson and i understand it but the problem is the notes (1/4, 1/16...)
I don't what's that mean and where i can use it ?

It's time for music theory.

4 beats per measure. 4 16th (1/16) notes per beat. It's basically simple math...if you know how fractions work.
