Instrument of Murder: Going along with the music motifs, a number of characters use weapons shaped like instruments.
Older than They Look or Younger than They Look: Due to the graphics, everyone in the main party looks anywhere from twelve to seventeen, even Frederic, who IRL died at 38. Notable exceptions are Legato and Tuba who genuinely look middle-aged. Beat, March and Salsa are all kids and therefore really are as young as they look.
The Leader: Of The Team. The other characters defer to him for some reason. At one point, Viola refers to him as "fearless leader," though admittedly mockingly.
Innocent Blue Eyes: Downplayed as he is less naive than Beat but believes he can talk Count Waltz out of the high taxes for everything except Mineral Powder.
Jerkass: Allegretto's interactions with Beat can sometimes come off as less 'playful' and more 'just plain nasty', as well as the time he ditched atoning for his crimes so he could spend time with his crush, leaving the rest of the party to do all the dirty work. Not to mention that time in Double Reed Tower when Beat explains the emotional significance of his camera, it being a cherished possession left to him by his father...and Allegretto immediately teases him about it, makes him cry and run away, and acts like it was no big deal that he just dismissed an important part of Beat's life. When Polka explains what Beat was feeling, Allegretto dismisses her too, though marginally less blatantly, since he likes her. Interestingly, this scene does not occur in the PS3 version.
Jerk with a Heart of Gold: More pronounced when he mocks Fréderic, and blows off atoning for his various crimes, forcing the responsibility on to Beat and co. to go and hang out with Polka. However, he genuinely cares about Polka and there's his Robin Hood act.
Ill Girl: It's established very early on that she won't live to see her twenties.
Innocent Blue Eyes: She's willing to give anyone the benfit of the doubt and believes she can talk to Count Waltz and make him understand how the taxes on Floral Powder are making it hard for her family to make ends meet.
Magikarp Power: She has rather low HP and Defense, is an average Echo builder, and while having long range attacks (Shade Comet, Shooting Star) along with good short-range Skills (Disruption Wave, Nether Wave), she gets more overshadowded as more characters are introduced. However, as she levels up, she can learn Earth Heal, which heals everyone else except her, but at a higher power than Viola's Heal Arrow, and if she goes further, she'll learn Blossom Shower, the best healing Skill, which heals the entire party in the field.
The Medic: She has more healing spells than anyone else and they are the most potent.
Plucky Girl: Usually, though the game makes it apparent that she isn't always plucky.
The Pollyanna: invoked in that she keeps up the act for the sake of the rest of the party. The weight of her condition does bring her down, but she only really angsts about it when she's alone with her mother.
Cloudcuckoolander: In story the rest of the party find him a bit odd at times given that he acts.... well, like he's stuck in a dream.
Final Boss: After dealing with Legato, he challenges the Polka and Co. to a final battle, Convinced that he must confront the others so that his soul might finally find rest and to stop the destruction of the dream world.
Dark Reprise: His battle quotes don't change at all, but they seem a lot more sinister when they're directed at YOU (particularly his "soulless creatures" taunt.)
Dream Sue: Considering the story takes place inside his dream, and he is aware of this, he expects himself to be all-powerful. It baffles him that he isn't and the others mock him because he's not.
Glass Cannon: Chopin is very frail, but is always able to deal out pretty good damage. Once he gets Phantom Pain, this becomes even more clear.
The Last Dance: He pulls out all the stops for the battle too. He whips out a couple of spells and specials that he can't even use in normal gameplay, plus a more powerful version of his "Orzel Bialy" attack.
Took a Level in Badass: When he moved into the dream world. The real Chopin regretted not being able to fight alongside his countrymen in the revolution in Poland. He's clearly enjoying his power in the dream world - "Strength that all can see!"
Your Mind Makes It Real: His state relative to the state of the world is ambiguous. Check the WMG page for details.
Unexplained Recovery: If he beats you in the final battle, the dream ends and he wakes up. This is the BAD ending mind you.
The Big Girl: Her lifestyle shows in her combat strength. She can do more damage from a distance than Retto can up close.
Boobs of Steel: She's both older and more developed than Polka and Marsh and Salsa and Serenade and she also hits harder.
Combat Medic: She can wipe out enemies with "Sacred Strike" and then support allies with "Heal Arrow".
Cool Big Sis: Very much so to Polka. There's a scene after the party split where she gives Polka a pep talk regarding crushes.
Crutch Character: She's a Game Breaker when she first joins because her arrows- although slow- can do absurd amounts of damage from a distance, and she has the first all-party healing tech you can get. She is also a decent Echo-builder if the player finds the need to use her in close combat. However, in the later stages of the game it becomes more important to hit faster than harder (to rack up Echoes) and other characters gain better healing abilities. This is exasperated in the PS3 version, where her firing and movement rate was lowered even further. If you can manage to get them to hit, though, her arrow attacks are more damaging in the PS3 release. Unlike in the Xbox 360 version, she is also granted a weapon that places her in permanent Burst, making her even more of a powerhouse.
Everyone Loves Blondes: Averted to her displeasure. She has a crush on Jazz but he's too focused on Falsetto (grey/brown) and Claves (red).
Tsundere: Type A, towards Beat. She likes pointing out that he's shorter than her and generally acting tsun-tsun but in the final dungeon she admits that she "wouldn't mind" Beat coming by the forest to visit.
Lightning Bruiser: While her slightly below average speed and attacks stats would seem to contradict this, her actual combat speed is the fastest in the game bar none, and the ability to pretty much always score a Harmony Chain means her damage output will never be as paltry as her stats may seem.
Pointy Ears: Both she and her sister have these. It's heavily implied that both are Not Quite Human, though exactly what they are is never stated specifically (perhaps some sort of elves?)
BFS: It's as tall as he is and he wields it with both hands.
Chick Magnet: Both members of his inner circle (Claves and Falsetto) are in love with him. Later Viola develops a crush on him. He is dating the first, aware of the second, and unaware of the third.
Dub Name Change: From Jiruba (Jitterbug) to Jazz.In both cases, why would a game about Frederic Chopin have a character named Jitterbug or Jazz considering the fact that Chopin never lived to hear Jazz music when it was created later on? The answer is Rule of Cool and Musical Theme Naming.
Genius Bruiser: Smart enough to lead the rebel army and strong enough to take down lesser enemies in one hit.
Instrument of Murder: His sword resembles a brass instrument of some type (French Horn or Trombone, take your pick)
Made of Iron: He can take much more of a beating than his two companions.
Mighty Glacier: He is one of the slower characters and he is also one of the strongest.
The Stoic: He is calm and methodical most of the time. When the root cause of the rebellion comes up, he is more emotional but still more subdued than others.
Stone Wall: Slow and capable of taking a pounding without danger. However, this cuts into his damage potential immensely, as he gets far fewer turns, and his high ATK stat is less impressive than it may seem, as his specials are actually rather paltry compared to other members of the team.
Supporting Leader: He leads the biggest group against the Big Bad and shares goals with the main party but has a small role in the story.
Lady of War: Her fighting style is more elegant and less brutal than Falsetto's martial arts.
Magikarp Power: Starts weak particularly compared to the rest of the party at this period, and after she is revived, she's at the exact same level she left at, meaning there's probably a difference of about 30-40 levels between her and the rest of your party. However, she has some of the best stat growths in the game, and at high levels, is pretty damn powerful.
Master of None: She starts out weak, frail and pretty slow. As she start hitting the higher levels, she can usually compete for top stats in any category(in the 360 version, she was second only to Jazz in HP and ATK, and either tied or was just outright best in the others), meaning she will end up as a Master Of All.
Rose-Haired Sweetie: Two contrasts with her tomboy romantic rival are her pink hair and sweet tempered personality.
Super Speed: Surprised? Thanks to her high stat growths, she eventually shares the highest speed in Xbox 360 with Falsetto and is second only to Serenade in PS3. However, her combat speed is low, as she runs slow and doesn't hit fast.
The Mole: She works for Count Waltz and provides him information about Andantino's movements. She's the reason Tuba thought the main party was from Andantino when they arrived at the castle.
Lightning Bruiser: In the 360 version. She's the fastest character along with Claves(and is faster for all levels before the final one), has higher damage output than anyone else per turn due to superior attack power, superior special attacks, echo building and gauge boosting. Her defenses are just slightly worse than Allegretto's . Add an automatic level up and you have a Game Breaker. Despite massively lowered stats in the PS3 version, she's arguably still one. Her only real problem is a lack of availability, and she still has more of that than more or less every character that can compare.
Martial Pacifist: Despises fighting and does all he can to avoid war, but he is a great fighter.
Mighty Glacier: In combat, he moves slow and he hits slow, but he has some of the hardest hitting specials out there, and there is no character in the game that comes close to his defensive prowess. Despite this, his speed stat is average rather than low, so he gets to take turns pretty often, unlike fellow slow and defensive character Jazz.
Royals Who Actually Do Something: He does all he can to protect Baroque's peace. Even if this means surrendering to Waltz which he acknowledges as suicide. The others chew him out for his stupid, yet well-intentioned, action.
Becoming the Mask: She's a spy for Forte and it's heavily implied that she has feelings for Crescendo.
Combat Medic: Many of her spells are attacks but one of them can heal the entire party.
Declaration of Protection: Gender-flipped trope. The princess is the one declaring to protect the prince. "I will protect Prince Cresendo" is one of her battle quotes.
Everything's Better with Princesses: Princess Serenade is from Forte, but they're ruled by a Count, who in traditional kingdoms is much lower in rank than a prince or princess. It's possible that she was given the title of princess when she got engaged to Crescendo. In one scene, Waltz refers to her verbatim as "a princess of Forte." Their Nobility Is Different From Our Nobility? There's also the possibility that women can't inherit the throne, and that Waltz is simply the closest relative(or even just a temporary ruler) but this still requires a bit of reaching. Apparently they just wanted a princess in the game.
Game Breaker: Once playable, she makes Falsetto look like a joke.
Idiot Hair: She isn't an idiot herself, but amusingly enough it sticks up through her tiny little crown.
The Mole : She is also a spy for Count Waltz. Her purpose was to convince Cresendo against starting a war so Waltz had time to prepare. She justifies her actions by saying that she would have done such a thing anyway.
Master Of All: Serenade is the fastest character in the game, among the tankiest, has one of the best healing spells in the game, and her two Light Specials are by far the strongest attacks in the game. Not even Allegretto's Infinity+1 Sword can beat her out in the damage dealer department.
Super Speed: Noble White, an armor that only be equipped to her, increases her speed stat by 20%. Even unaugmented, at the highest levels her speed stat is the highest and exceeds even that of other characters that are known for speed, including Falsetto and Salsa. On the other hand, her movement and attacking speeds are below average.
White Magician Girl: She looks the part, is a pacifist, a love interest and she has a move that heals the party.
The Caligula: He's willing to turn his own subjects into monsters to take over the world; Not the best way for a king to treat his subjects.
Cool Crown: Because he's the ruler he gets to wear one of these.
EvilTeen Genius: The mastermind of the whole mineral powder operation is only 16 years old.
Evil Plan: Use mineral powder to create a Super Soldier army and invade Baroque so he can 'carve his existence' into the world.
Faux Affably Evil: Carries an air of regality about him, but none of it is real and is only for appearances. Sometimes he won't bother pretending.
Jerkass: Turning his whole country into a bunch of mindless slaves certainly counts towards his evil street cred.
Lack of Empathy: His response to the news of Tuba's death? He feels more sorry for the bridge. That tells you all you need to know about him in this regard.
Large Ham: Somehow he can chew scenery while sounding bored on his throne.
Purple Is Powerful: He wears an outfit and crown featuring royal purple as the central color.
Royal Brat: Technically not royal but he is the ruler and behaves like a spoiled child when one of his minions fail.
Slouch of Villainy: He spends most of the first five chapters lounging in his throne. He even finds another one to lounge in at the top of the Double Reed Tower when the party confronts him again.
The Sociopath: He doesn't care about mineral powder's negative side effects as long as it works.
Straw Nihilist: Outlined in his speech in the Double Reed Tower in the PS3 version. "...all human begins are fragile. Especially those who lack power. They die quite easily. And when you die, it's over. There's just no meaning to it. .... That's why I must have power. Enough absolute power to carve my existence into the very fabric of this world."
Taking You with Me: When beaten for the final time, he decides to take the whole world with him.
Villainous Breakdown: In a moment of "If I can't have it no one can", he orders Legato to destroy the world in one final blast.
Would Hit a Girl: Slaps Polka hard enough to knock her to the ground. This was after she surrendered and he said he wanted to keep her in good health. It's another reason to hate him.
Fat Bastard: One wonders how he gets his armor around that big belly.
General Ripper: The first thing he does when the party gets to Forte is attack them. Why? Because OBVIOUSLY they're part of La Résistance!
Jerkass: He has no trouble smacking a small child like Beat down to the ground just because he can. Unfortunately for him, Beat isn't as weak as he looks, and manages to pay him back for this later on.
What an Idiot: invoked As Count Waltz comments— "Did you really expect them to just come marching in the front door?"
High-Class Glass: In the PlayStation 3Updated Re-release of the game, it earns him the mean nickname "three-eyed freak" from Salsa. Even March uses it, which is unusual, given her Blue Oni status to Salsa's Red Oni. Naturally, it really tees Fugue off. "Little girl, I hope you aren't referring to me."
Hopeless Boss Fight: The first battle against him. It's a level 8 Polka and Frederic against him, and he can kill them both in one hit.
Jerkass: Beats up strangers for no reason, kicks agogos to show up his meanness, etc.
Katanas Are Just Better: There's no analogue for Japan (surprisingly enough), but he's got a katana. Given the nature of the world, it's unlikely Chopin ever saw one, so... yeah. He's an anomaly.
Large Ham: He likes to speak and act theatrically before comitting random acts of violence.
The Sociopath: He'll kill two innocent bystanders just because he's wet.
