I don't know how to even begin to answer this question. To be quite honest I don't know what you mean. There is no 'sharpest' or 'clearest' note. If you are asking about how a note comes through on a recording, well then that's down to the mix engineer. If you are asking whether there is a single note in any given musical scale that is more prominent that another then my uneducated answer would be there isn't one. You can play the same note on different instruments and they will have different levels of 'penetration'. If you are looking for a 'magical' note that will make your track/song more prevalent than others you are wasting your time. I might be wrong, but it seems to me that you think there is a note that is going to make your music sound better. It does not exist.
