Anime soundtracks can be considered the backbone of any series. When done right, they fully convey the tone of the story and can further enhance the viewer's emotions.

Every anime has its own set of opening and ending themes, as well as a variety of instrumental pieces used throughout. Here are some of the best emotional anime music tracks that often bring tears -- and why they arouse so many emotions.

Violet Evergarden: “Michishirube”

Violet Stands By The Window In Violet Evergarden

Violet Evergarden is a tragic tale of war and love, so it's a given there will be a plethora of emotional songs accompanying it. Violet bears witness to many stories and relationships through her work as an auto memory doll, but what makes these moments even more emotionally fueled is the series' closing theme song “Michishirube”.

Unlike a lot of anime, the ending song in Violet Evergarden is not just a way to fill time as they show the credits; it's incorporated into the most emotional moments, which are often at the end of the episode. This is done by playing "Michishirube" a few minutes before the actual conclusion, serving as an accompaniment to the most significant scenes. From Princess Charlotte preparing for her wedding to a montage of a daughter receiving her mother's letters years down the line, the song has become synonymous with the impact Violet has in the lives of her clients.

Angel Beats: “Ichiban no Takaramono”

Characters from Angel Beats!

Angel Beats has long since established itself as one of the most iconic tragedy anime alongside series like Death Parade and Plastic Memories. In the realm between life and death -- designated to help the souls of people who died unjust deaths to move on -- the entire setup is immediately sad. Angel Beats is notoriously good at incorporating music with its darker themes, and its ending theme “Ichiban no Takaramono” has nearly exceeded the show’s fame in itself.

Almost every anime fan will have heard this poetic song driven by the chords of the piano at some point, even if they haven’t watched the show themselves. The name of the song can be roughly translated to “My most precious treasure” and the lyrics weave a bittersweet tale of parting and moving on. When used as the background music to one of the biggest emotional climaxes in the series -- the parting between Yuzuru and Kanade -- it truly nails the final lid in the coffin of being an iconic tearjerker.

One Piece: “Bink’s Sake”

Lauded as one of the most iconic anime to date, One Piece has been running for well over 1,000 episodes by now. Throughout its runtime, the series has seen no shortage of memorable and emotional tunes -- none of which can be quite as emotionally significant as "Bink’s Sake".

This catchy folk song was commonly sung among older pirates as a way to uplift the spirit. As a former member of an old music-loving pirate crew known as the Rumbar Pirates, Brook is no stranger to the song. In fact, it becomes symbolic of his past and his promises as well as his hope for the future with the Straw Hats. "Bink's Sake" truly demonstrates the power of storytelling and the meaning it can lend to a seemingly bright tune. From watching the Rumbar Pirates succumb to poison while playing the song to Brook’s promise to Laboon, its no wonder that One Piece fans still find themselves teary-eyed when hearing this tune.

Naruto: “Sadness and Sorrow”

Naruto is an immensely popular franchise with a plethora of memorable music tracks, but one of the most iconic of all is the tear-jerking “Sadness and Sorrow”. First appearing as an accompaniment to the scenes of Zabuza and Haku’s deaths, it has since established itself as one of the most heartfelt instrumental pieces in the series.

"Sadness and Sorrow" gives the vibes of classic Japanese music, with its predominant use of the flute and other traditional Japanese instruments throughout much of its duration. Since establishing itself as a sad theme, it has been used as the background music to flashbacks of Naruto’s lonely childhood among other instances.

Demon Slayer: “Kamado Tanjiro no Uta”

Anime Demon Slayer Tanjiro Nezuko Destroy Rui

First introduced in Episode 19 of Demon Slayer, “Kamado Tanijiro no Uta” served as the perfect backdrop to one of the series' most jaw-dropping scenes. Tanjiro and Nezuko face off against Rui, one of the first Lower Moon demons they encounter. The odds are stacked impossibly against them and Tanjiro knows it. Relying on the memories of his father and with the assistance of Nezuko’s Blood Demon Art, Tanjiro uses the Hinokami Kagura for the first time and manages to land a strike on Rui.

Orchestral instruments are featured predominantly in this theme, giving it a dramatic and almost cinematic feel. The lyrics are simple and spaced out between the instrumental ups and downs, adding to the feeling of tension. When paired with such an emotionally and thematically significant moment in Demon Slayer, it certainly makes for a memorable soundtrack.

Puella Magi Madoka Magica: “Decretum”

Madoka Magica Sayaka Comforting Madoka

Puella Magi Madoka Magica is heralded as one of the first magical girl anime that successfully put a dark twist on what was generally accepted as a cutesy genre before then. “Decretum” is Sayaka Miki’s theme and is probably the most memorable individual character song throughout the series.

Sayaka’s personal arc from hope to eventual despair is one of the most fleshed-out displays of the tragic fate of magical girls. Viewers get to see her entire process of becoming a magical girl to eventually becoming a witch in despair. “Decretum” is played throughout all the significant moments in her story. The instrumental piece is led by the sorrowful cords of the violin and accompanied by the sounds of other string and wind instruments, making for an eerily mournful theme.
