When you start listening to dissonance it leads to querying how melodicism works or why sounds which are less sweet are unacceptable. Most pretend strangeness is best left alone. A normal mind avoids it the way a shaky pianist avoids an unfamiliar key signature. When you try to think about all you don’t know, about the fact that there is no you, your thoughts will warn you off like a discordant chord. Because if it is true, if you manage to hear that music includes all sounds, and calling yourself I is merely another thought, you are left with a new riddle and no human mind can answer it. Noticing is everything.
