Studio

The Studio (スタジオ) is an area in Rhythm Tengoku accessed through the main menu. Here the player can listen to the music they've unlocked through the Perfect Campaign, as well as make use of their Drum Lessons by drumming to the music. Some Perfect Campaigns reward new drums to try out in the Studio as well.

After getting all Perfects, the Barista adds more music to the Studio.

Gameplay
Here the player can access a selection of tracks from the game, depending of the amount of Perfects obtained thus far. On the MUSIC LIST, the player can choose to listen to music, drum to it, move the tracks around or mark them. While Listening (リスニング), Anata appears in the Drum Lessons area, but instead of playing, he drinks coffee while the music plays. The Samurai Drummer is absent as well. The background displays various patterns or scenes depending on the track. After the song ends, it moves on to the next track that has a checkmark in the list, and loops to the top after the last track. Unlike the next two games, the player can't set the tracks to shuffle or play in order, and the tracks are usually in whatever order they were added as Gifts through the Perfect Campaign unless the player decides to move them around. The player can press the Select button to return to the Studio menu at any time. When the player chooses Drumming (ドラミング)', they first must choose the drums from the DRUMS LIST, collected from the Perfect Campaign. The various drums make different sounds. The controls are the same as in the Drum Lessons, and they can be considered a "practice" of sorts for this mode and Live. While drumming, the normal drum beat of the song is removed. After the song ends, the player can save their performance, which is marked with an "M" symbol. Choosing the song without selecting any options plays the saved performance, or only the music if no performance data is saved. Only one performance per song can be saved and up to 10 in total. Choosing "Drumming" when there's performance data will prompt the player to delete it. There is also a silent track which allows the player to drum freely, essentially composing a song.

The player can use Narabikae (ならびかえ) to sort the music and Check (チェック) to mark a track for Listening mode.

Music List
The very first track in the list is pure silence, allowing the player to compose their own music on the drums. Here, the prompt to save the performance happens when quitting with the Select button, as there is no "end" to reach. The player cannot mark it, and thus cannot listen to it.

Trivia

 * Several tracks in the Music List differ from what they are like during gameplay. For example:
 * Night Walk's tempo is a little slower than in-game.
 * Spaceball and Marching Orders end after the point the games would fade out.
 * Sneaky Spirits 2 loops twice without any tempo changes.
 * Iai Giri, Rat Race and Bunny Hop use specialized tracks meant to help with their gameplay during the game, and they have separate ones specifically for the Studio.
 * Showtime is a looped track, while the game ends before the first loop completes.
 * Tram and Poline is also looped twice with a defined end.
 * Power Calligraphy has an extra hyoshigi click which isn't heard during gameplay, as it ends before the last note plays. It can still be heard in Rhythm Tengoku Complete Music Collection and in future games.
 * Polyrhythm speeds up on the second half, and has a defined ending.
 * Remix 1, Remix 2, Remix 4, Rap Men, Rap Women, Ninja Bodyguard, Baikin Hakase, Uma Machine's four tracks, the three Practice Themes, the music from the Rhythm Toys, Endless Games and Drum Lessons Selection Menus, the Rhythm-kan Sokutei Results Theme, Rap Machine, and the arrange variants aside from The Snappy Trio, Bon Dance, Cosmic Dance and Tap Trial 2 are all missing from the music list.
 * Most of these differences are shared with how the tracks are represented on the Rhythm Tengoku Complete Music Collection, with the exception that Tram to Poline fades out when the game would end, rather than looping, and most of the missing music is included.
 * Rhythm Heaven and Rhythm Heaven Fever allow the player to listen to music in much the same way through the Café, where once again most tracks need to be unlocked as gifts from the Perfect Campaign. The player cannot drum to them, however, nor can they sort the tracks. Instead, they can choose to listen in order or shuffled.
 * In Rhythm Heaven Megamix, the player is able to Play Music and view the epilogue slide show in the Museum, the music being purchased from the Shop this time. If they start them while pressing down 🄻 and 🅁, they can drum to the music with the same controls as the Drum Lessons and Studio . Rather than playing as Anata, Spooky of the Tiny Ghosts is used instead. The player cannot save their performances.
