How to mix and bring clarity too two separate Frequencies that are occupying same space

Ok I have two separate tracks

Low bass line and a low piano playing octaves

Now I First try volume balancing

and I can hear a-bit of distance between the two Frequencies

But need a lot more clarity

[br]Now these two low frequencies are muddying up and masking each other up in the mix

[br]On the form or YouTube what should should I search for ?
