Strike Your Note

 In Music of the Ainur by Tolkien, we read the following..

 "The next Theme had a sound unlike the others before it. It began quietly amid the confusion of the Second Theme, and sounded like the rippling of soft and sweet notes. It gained power and depth over time, until two completely different songs were being made. One was filled with "immeasurable sorrow", which gave it tremendous beauty, while the other was a loud, pompous theme playing in violent opposition to it. Nevertheless, this repetitive theme could not overcome the sorrowful one, and the latter merely took the former's greatest notes and "[wove them] into its own solemn pattern". The strife between the two themes caused the dwelling of Ilúvatar and even the Void beyond it to shake. At this point, Eru stood once more and raised both his arms, "and in one chord, deeper than the Abyss, higher than the firmament... the Music ceased"."

This is where we are in the song. There is a lot of instruments out there making their music.  Some are looking for unity of sound and harmony, while others are trying to drown it out with discord.  However, there is a purpose beyond the moment..

"The Ainur saw a Vision of what their song had created— "a World that was globed amid the Void... but was not of it". They saw the history of this World as it unfolded, and witnessed the part each had played in its making. Even the discords of Melkor contributed to the glory of this creation."

You may not understand it, and it has taken me most my life to see it. But, the dark notes matter.  Darkness has as bit of a part to play in the creation of your story and of you than does the light.  If you shelter yourself from it, you will find yourself less than half of what you could become.  It is easy to stay a sheltered child, but if you wish to actually grow and know the whole of what the world is and what your part is to play in it, you must be willing to understand the sad notes.  Then, you will understand joy.

You have a part to play in the song.  You.. yes.. even you.. have a voice to be used, an instrument to add to the song that has been going on long before you were born and will continue to do so long after you are just dust.  The universe is billions of years old and will continue for a billion more.  Best you can do is to learn how to play YOUR instrument to add to the song.
