Is saying ( just as how I play piano) grammatically correct? Thanks in advance

plutôt :

just like the way i play piano..

Hello

the sentence just a how i play piano is not grammatically correct

( just as how I play piano )

you can say instead if you are asking someone how to play the piano we say ( how do i play the piano )

or if you are showing someone that you can play the piano we say ( look at how i play the piano ) or ( look i can play the piano ) or ( i can play the piano ) or ( i just like the way i play the piano )
