Impulse/ impetus and long phrases.

Hello. I was practicing fantasie impromptu by Chopin and that professor heard it and said that I need to handle it a different way. He said that the left hand is grouped as six notes and need to played that way. He said “you won’t be able to play the whole piece playing everything like legato in the LH. you need to play the six notes as written and then give a little impulse for the next six notes.
He said that when I have a longer passage I need to divide it somehow in my head and give impulses as well.

I was wondering if it is true for every piece? For instance Mozart Sonata k545 has the Alberti bass in the LH and there are no slurs ….

I'm not sure I understand your professor's comment based on how you are describing it. Do you play all the left hand sixtuplets as one stream of notes without any rhythmic accents, so to speak?

I haven’t really thought about it. I probably do

I would not consider this a principle to apply blindly to every piece. In many pieces from the baroque, classical and romantic eras you want to feel the pulse in the music, so it should be highlighted somehow, but don't just blindly hammer it out haha. It would help if you posted an example of you playing Fantaisie Impromptu and maybe we could give feedback and better understand what your professor reacted to.
