Shadow on the Bridge is not only awesome, but it's an effective Tear Jerker.
Elise Deauxnim's/Misty Fey'stheme: Gentle Melody. Does a nice job of portraying Elise as a kind, gentle woman, as the name of the song implies.
Being the final game in the original trilogy, the court themes for Trials & Tribulations have a strong sense of finality to them that make the atmosphere of the court heavier than at any other point in the series. In particular, the trial music playing immediately after Godot delivers his Tears of Blood quote over silence at the tail end of the final case. Best musical cue in the entire series to date. The new version in Ace Attorney Investigations is also a classic.
The remix used in the end credits medley of Trials and Tribulations gets a lot more epic, and in some ways sad. Partially because the last case cemented Wright's career and role as a respectable attorney, and partially because it's the last game in the Phoenix Trilogy, meaning we leave behind all the people and adventures for one hell of a great memory. Makes you wonder exactly what has happened with all the characters since those seven years in the canon timeline and if we'll be seeing them again in the future installments.
The Enemy Who Surpasses The Law (be advised that the biggest spoiler of all is on the complete name of the song so enter under your own risk), which shows you just how powerful and haughty the Big Bad is. It is the kind of masterfully composed and executed piece of music you would expect in a game like Kingdom Hearts, famous for such soundtrack. Especially powerful when it plays for the first time in conjunction with The Reveal.
This song was especially amazing when near the very end, you thought you had just solved the case... When BAM the song came, and you thought to yourself "Oh Crap, what sort of trick did he pull now?"
While Gumshoe already had a theme (in the Phoenix Saga), that one had a more slow-paced serious tone to emphasize the seriousness of the cases and also to give the "Gumshoe scenes" a "crime series" atmosphere. The AAI rendition of the song is more up-beat and was clearly made to give Gumshoe a song that emphasized his goofy and clumsy (and adorable) personality but also conserved his leitmotif of the Phoenix Saga as well, so this version can be considered his real theme while the first one can be considered the Police Detective theme.
"The Great Truth Burglar" for Mikumo Ichijo/Kay Faraday. Using different traditional Japanese instruments in abundance, it feels like a second Steel Samurai theme.
Although it only appears in one case, there is the track Guardians of the Law. Partially based on the trial themes of the first and third games, the epicness of this music only makes you wish it played more.
Ace Attorney Investigations 2
Kay's and Lang's themes are remixed into Reminiscence songs. How... sad...
"Objection!" 2013note presumably this is Phoenix's Objection theme and Apollo will get his own when you control him in court. Take the "Objection!" theme from Trials & Tribulations and redo it with string instruments and you get this; a smooth and stylish way to lay down the finger. Plus they threw in a really jazzy breakdown section in the middle.
One of those (Mysterious Masked Person - Please Listen!) gets another crowning due to what it's paired with. Throughout the case it's used both for Mask* DeMasque and Ron DeLite and is generally flamboyant and awesome, but at the end of the case it plays when Desiree declares that she still loves Ron, demonstrating that she accepts him despite his thieving ways.Crowning Moment of Heartwarming, hello.
"Suspense" is such a simple theme, but it demands your utmost attention from the moment it kicks in.
There's this tiny thing called "Jingle" and it plays every time you complete a chapter or a case. It's extremely short (at the most about four seconds). But the feeling of satisfaction and awesome you get when it plays...
The entire Jazz album. All of it. They're not just good remixes, they're really great jazz songs. The Steel Samurai Theme is amazing. Come on, would you be suprised if this was from an 40's cop show? Also Godot's Theme and Furio Tigre.
You think these remixes are good on their own? Try Unlimited Corners, a mashup of several entries on this page. Words cannot describe the experience of listening to it.
And of course, when Phoenix/Naruhodo goes to Marvel, he takes not one, but two of his themes with him (and is the only character in the series to have two themes.) This and this. Listen, and behold, you will realize, they're iconic music made Up to Eleven.
