Thanks to the nature of beat saber's gameplay, the grips themselves don't necessarily have to be held with the same certainty as, say, a gun. Due to this, the community has developed several hand gripping styles. Fortunately, these might be just the thing keeping you from being the song saber samurai you dream of being. There are also various third-party attachments available to allow you to, for example, take to the beat like Darth Maul. As I have yet to try using this attachment, your mileage may vary. Personally, I think it looks like it'll make the side-by-side notes impossible.
