The eighth entry in the Pretty Cure franchise.In the musical world of Major Land, peace is protected by the "Legendary Score" and the Melody of Happiness contained within. On the annual performance of the Melody of Happiness, the Score is stolen by the jealous king of Minor Land, Mephisto, who turns it into a Melody of Sorrow. To stop Mephisto from sucking the happiness from Major Land right then and there, the queen of Major Land, Aphirodite, scatters the Notes of the Score and sends them to Earth. She then instructs Hummy, the Songstress chosen to sing the Melody of Happiness that year, to go to Earth and retrieve the Notes before Mephisto can.Meanwhile, middle school sophomores and former childhood friends Hibiki Houjou and Kanade Minamino are recovering from yet another fight with each other when they encounter Siren, a former Songstress of Major Land who has defected to Mephisto's side. Siren attempts to take the G-Clefs within their hearts for the Melody of Sorrow, but accidentally triggers an amazing potential, causing the girls to transform into Major World's champions, Pretty Cure.As Cure Melody and Cure Rhythm respectively, it's now up to Hibiki and Kanade to work with Hummy and gather the Notes of the Legendary Score. However, it's not so simple: the Pretty Cure power is fuelled by The Power of Friendship, and the two former-friends have many, many issues that they need to work out first.The Pretty Cure Power Trio is later completed with the arrival of Cure Beat, Siren after undergoing a Heel-Face Turn and being stuck in human form as Ellen Kurokawa. They also have an Aloof Ally called Cure Muse, a mysterious masked fighter who helps out Pretty Cure but claims no affiliation with them until revealing herself as Ako Shirabe, the daughter of Aphrodite and Mephisto.
Badass Family: In a musical sense. Hibiki's dad is completely immune to the Melody of Sorrow because he believes music should make people happy. Her mother goes a step beyond this and can actually counteract it with her violin. However, Hibiki's dad finally gave in a little against the Negatone in episode 41, though it can be justified that at that point, the Negatones have gotten more powerful for someone like him.
Also the royal family of Major Land. One's a Precure, one was a major villain, one essentially gives the Cures their powers, and the last one...
Big Damn Movie: Torimodose! Kokoro ga Tsunagu Kiseki no Melody! What happen if the sole survivor of Majorland points out the Big Good is the one who turned Majorland's citizens into Fate Worse Than Death? And by contrast of most Precure movies, it explicitly deems canon by Word of God, placed between episode 36 and 37. And also serves as foreshadowing; Howling's action in the movie actually has the closest result as Noise's true goal, which then he does so himself in finale arc, than his other minions.
Book Ends: Both the first and last episodes ends with Transformation sequences.
Brown Note: Everytime a Negatone produces soundwaves, everyone within range falls into sadness.
Evil Is Petty: To be sure, Mephisto wants to take over Majorland, but rather than actually rule it or anything, he just kind of seems invested in making everyone sad all the time. Turns out, he was brainwashed by the real Big Bad, with said Big Bad actually aiming for an utopia of some sort through the aforementioned 'taking over Majorland' business.
Evolving Credits: After Cure Beat joins, the opening theme is also remixed to have more of a beat.
The opening and second ending adds Cure Muse in episode 38. For the latter, Hummy had been dancing in her place until then, and is relocated in the final product.
Food Porn: Anything anyone from the Pastry Club (Kanade in particular) bakes might very well leave your mouth watering. Heck, a Japanese fan tried making the black spider cake from episode 4 in real life, and it came out pretty accurate.
Grey and Gray Morality: Noise, the so-called ultimate evil, is actually a personification of sorrow that people made as a scapegoat of their sadness. He being said as 'evil' by people of Majorland is a form of Fantastic Racism and he ends up so bitter and angry at this that he would rather die himself. Too bad that the only way for him to die is for other people, in all but name, to die too.
Bassdrum and Baritone pull one in episode 42 but eventually get brainwashed by Noise by the end of the episode. They pull another one in episode 43 where it's revealed that they, along with Falsetto, were good all along and were all turned evil by Mephisto when HE was controlled by Noise.
Magic Skirt: In episode 2, the girls were hanged upside-down from the tree, yet their Precure and school uniform's skirts stayed as if they were standing on the ground.
Meaningful Name / Theme Naming: The first character in Hibiki and Kanade's surnames are the characters for North and South respectively, while Waon and Seika's have the characters for, respectively, West and East, which led to many fans guessing that they would become Cures later on (see Lying Creator on the Trivia page).
Hibiki and Kanade's first names are also significant and fit with the musical theme of the series. The term "hibiki" means a sound, a ring, or an echo. Used as a verb, it can mean to resound/resonate. The term "kanade" means to play or perform, such as with a musical instrument.
Ellen and Ako are named after Electric and Accoustic (as in, string instruments) respectively.
Mid-Season Upgrade: Taken to Lensman Arms Race levels. Melody and Rhythm gain three upgrades over the course of ten episodes: the Belltiers, Belltier Seperation, and Belltier Crossrod. Then five episodes later Cure Beat joins, essentially acting as a fourth upgrade by joining in with their previous attacks.
Not-So-Harmless Villain: Trio the Minor. After several episodes of standing in the background and acting as Siren's wacky sidekicks, the three are revealed to have gathered a good deal of notes on their own, whereas Siren has yet to gather even one. In episode 11, Bassdrum takes Siren's leadership position after Mephisto demotes her and immediately stages a trap that came much closer to defeating the Cures than any of Siren's plans ever had. Later in the series after their Mid-Season Upgrade they also succeed in suckering the Cures and stealing all of their notes save for the one they got from that episode's Negatone.
Then it turns out any one of them can become the next King of Minor Land should Noise deem it so.
Mephisto seemed like a rather silly villain until he cruelly brainwashes Siren on the brink of her Heel-Face Turn. He's still a doofus in most of his appearances afterwards, though. Then episode 34 happens.
Not What It Looks Like: In episode 15, when Hibiki and Kanade discover Ouji passed out... on top of Siren. Naturally, Kanade flips the hell out.
Pink Means Feminine: The initial flyer for the series went out of its way to point out that both mains wore pink in their Cure outfits, putting "girls' favourite color on full display".
Poor Communication Kills: Two at the same time in episode 6 — while Hibiki's trying to stand up for Kanade's brother Souta on what he was doing, both she and Kanade ignore Hummy who has found a Note and is trying to tell them about it.
This is also the reason we don't see Hibiki and Kanade get along in the first two episodes even though they are childhood friends. Hummy asks Hibiki why that is; and the latter responds that when they began middle school, Kanade was supposed to meet her at the third sakura tree from the school's entrance and never came. The misunderstanding came from the fact that the school has two entrances lined up with sakura trees. Both Hibiki and Kanade were waiting for each other at each entrance unaware of this fact. When they figure it out, they instantly forgive each other. Siren responds to this with the Lampshade Hanging above.
Pun-Based Title: Suite means "a group of related pieces of music or movements played in sequence." It sounds like sweet, and as it happens, Kanade is in her school's pastry club and her family owns a pastry shop.
Shout-Out: Siren's feathery neon-colored outfit in episode 5 is one to the Brazilian carnival. Maybe done on purpose, since the Brazilian carnival was being celebrated in the week the episode aired. The "butterfly-like ribbon" on her chest is also a Mythology Gag to Yes! Pretty Cure 5.
Spotlight-Stealing Squad: Hibiki, or rather, Cure Melody. The show is decently balanced normally, but come battle time, Hibiki kills more baddies, gets the Upgrade Artifacts earlier, does all the Rousing Speeches and generally has everything revolve around her. Unsurprising, given she's an expy of Nagisa and Saki, both known for being this as well.
Ako is often accused for this. Justified Trope since she joins so late in the series and only appeared once in a while before.
Stealth Pun: Hummy and Siren, the fairies that can sing the Melody of Happiness (or Sorrow), are cats. Typically, caterwauling is defined as particularly awful singing. Doubles as an Incredibly Lame Pun.
This Is Unforgivable: Hibiki and Kanade usually said this before their Transformation Sequence, to the point of Catch Phrase status. Deconstructed when Siren has a Heel-Face Turn. Hibiki and Kanade are so shocked at this and, remembering how many times they had said this, start questioning whether Siren is really unforgivable. The Reveal that all the initial antagonists are brainwashed and the real Big Bad is not truly evil also hammer the point down. By the time of Final Battle, the Cures finally decide that the only way they can have a closure is for both sides to forgive each other.
Villains Out Shopping: In episode 26, Mephisto is very annoyed to discover Trio the Minor chilling out at the beach. Baritone even built a sandcastle.
Vitriolic Best Buds: Hibiki and Kanade are a mild type two, which is one of the defining differences between them and NagiHono and SakiMai. Hummy and Siren are type one, with Hummy as the oblivious annoyer.
Watch Where You're Going!: Hibiki and Kanade have managed to crash into each other twice. Once in the beginning of episode 2, which sends them both into a tree, and then again in the beginning of episode 5, smacking their faces together.
