Music in Hey! Pikmin
Almost all moments of Hey! Pikmin have some accompanying music to set the mood of the situation, from the menu the player is using to the cutscene they are watching to the area they are navigating through. The soundtrack for Hey! Pikmin was composed by Masato Kouda and Kento Hasegawa.
Plays in the title screen and saved game selection menu. This theme presents an ethereal electronic atmosphere, somewhat similar to The Distant Spring's theme from Pikmin. After some time, the synthesizers are joined by a harp ostinato and some simple hand percussion.
Plays in the sector selection menu, where the player spins the planet around and chooses which sector to go to. This theme draws on grand orchestral styles, opening with a strong melody on French horn, to emphasize the grand scale of the adventure across the planet, but it also features a constant layer of electronic sound effects, as if the sounds of the S.S. Dolphin II are playing in the background.
Plays in the Brilliant Garden's area selection menu, where the player can pick which area of the sector to play in. This wistful theme uses instruments with cute tone colors such as flute, xylophone, and harp to introduce the upcoming adventure in a peaceful way.
Plays in the Verdant Waterfront's area selection menu, where the player can pick which area of the sector to play in. A strong intro sets up this theme's firm rhythmic style. A simple melody is then exchanged between xylophone and a twangy plucked string instrument over a solid E chord. Later in the loop, dissonant scales in the background (very similar to those in the underground back side theme) change the feel considerably.
Plays in the Sparkling Labyrinth's area selection menu, where the player can pick which area of the sector to play in. This piece contains 3 distinct segments that are very different in style. The main thing holding them together is the steel drum, which is a fitting instrument for this sector's crystal theme.
Plays in the Ravaged Rustworks's area selection menu, where the player can pick which area of the sector to play in. This theme is a lush bossa nova, with a melody played by raindrop-like and whistle-like synthesizers, and guitar and strings providing a jazzy background.
Plays in the Leafswirl Lagoon's area selection menu, where the player can pick which area of the sector to play in. This beautiful theme in 3/4 time includes a calm melody played by 2 flutes over a simple guitar line, and later a second section with a similar melody played by an accordion over a more full-sounding background. The resulting theme is fitting for an autumn landscape.
Plays in the Sweltering Parchlands's area selection menu, where the player can pick which area of the sector to play in. Compared to the earlier area selection themes, this one is much more synthetic, and contains more of an uncertain feel around it. A hopeful-sounding melody is undermined by higher-pitched synthesizers playing at odd times.
Plays in the Snowfall Field's area selection menu, where the player can pick which area of the sector to play in. This theme creates a snowy feeling without the use of sleigh bells, which is cleverly done with a mix of staccato notes and swelling long notes played on xylophone and strings, with plenty of space in between. The second half of the piece may be a reference to The Forest of Hope's theme from Pikmin.
Plays in the Lushlife Murk's area selection menu, where the player can pick which area of the sector to play in. This theme's strange synthesized sounds (plus a marimba) complement the poisonous swamp theme of the sector, without sounding too negative. The game may be nearing its end, but optimism remains.
Plays during the Hey! Pikmin logs menu.
Plays during the Pikmin Park.
Plays during the results screen of a Secret Spot, where the collected pellet or treasure is shown. This short loop moves between simple piano chords which are colored by a synth arpeggio playing the notes of the chord a fifth above. The resulting theme is more reflective than celebratory.
Plays during the results screen of a Sparklium Springs level, where the collected Sparklium is tallied up. This theme is the same as the Secret Spot results theme, but transposed up a minor third, and with a bright synth melody added. This creates a slightly more exciting texture.
Plays during the game over screen of a standard area, where the player can choose to retry the stage or return to the area selection menu of the sector they are on. This also includes the segment with the brief cutscene showing Captain Olimar being beamed up to the S.S. Dolphin II.
Plays during the "Try again?" menu of a Secret Spot, where the player can choose to retry the challenge or return to the area selection menu of the sector they are on. This can happen by letting Olimar be killed.
Plays during the options menu. If the player adjusts the music volume, the effect takes place right away, so the player can use this song to figure out how loud the music volume is.
Plays during most of the S.S. Dolphin II update cutscenes, for all scenes that aren't the ship talking about having discovered a boss battle area, since the Inside the S.S. Dolphin II - boss found track plays in those ones.
Plays during the credits sequence.
Unlike in previous Pikmin games, the music in areas does not change dynamically based on what is happening in the game, and is constant throughout each scene of gameplay. However, most areas have 2 themes: one for the front side, and one for the back side, with one version fading out and the other version fading in when a doorway is entered. Front side themes are the primary themes of the areas, and contain diverse musical textures. In contrast, back side themes are much more sparse and ambient, and are only loosely based on the corresponding front side theme.
Plays during the "front" side of most areas in the Brilliant Garden: First Expedition, Mushroom Valley, Back-and-Forth Road, and Cherrystone Pass. It also plays during the tutorial area after the crash-landing.
Plays during the "front side" of most areas that take place underground: Cavern of Confusion, Serene Stream, Glowing Bloom Pond, Springpetal Cave, The Hollow Sky, Space of Silence, Drenchnozzle Den, Lights in the Darkness, Terror Trench, Below the Ice, Ordeal of Flame, and Peculiar Rockfall.
Plays during the "front side" of the Sizzling Precipice.
Plays during Olimar's Madcap Ride.
Plays in all boss battle areas, including Fragment of Hope, in the section that takes place before the boss is actually encountered and fought. The player is unlikely to hear this theme for more than a few seconds, but even right at the start, tense string chords and dissonant xylophone arpeggios set a strong theme of tension. Later on, there are some unexpected harmonic shifts in an exchange between the strings and a bassoon.
Plays during a Secret Spot. This theme encourages completing the puzzle as quickly as possible, through creating constantly rising tension. This is done with lots of chromaticism, as the most common chord movement is a semitone rise upwards, and almost every part has plenty of contrast between neighboring notes. This reaches a climax when the piece breaks its pattern of chord resolution to modulate to a higher key, accompanied by a change to brighter synthesizer tones.
Plays during a Sparklium Springs area. This incredibly synthesizer-dominated piece uses many different electronic sounds and fast rhythms to create an exciting texture that fits the minigame well. The pop-style chords and melodies leave no time for hesitation or reflection – the goal is to get the Sparklium as quickly as possible.
Plays during the fight against the Bulborb.

Plays during the fight against the Berserk Leech Hydroe during its buried form.
Plays during the fight against the Berserk Leech Hydroe during its quadruped form.
Plays during the cutscene that takes place when the player collects a treasure (or Sparklium Seed) dropped by a boss, and the S.S. Dolphin II's pod beams up Captain Olimar, any living Pikmin, and the treasure. The exception is the Emperor Bulblax, since Emperor Bulblax defeated plays in that case.
Plays when a Secret Spot level is introduced, after the loading screen, and before the "Start!" message. The arpeggiated chords and scales in the jingle effectively state to the player that a puzzle is about to occur.
Plays during the short cutscene where Captain Olimar and the Pikmin celebrate having collected the pellet or amiibo treasure at a Secret Spot. This simple fanfare with a simple G-A-B chord progression features an interesting synthesizer tone playing a short melody.
Plays when Captain Olimar loses all of his health and the screen fades to black, in a Secret Spot. Using instruments commonly associated with sad musical themes, this jingle sets up a chord resolution and then doesn't resolve it, to emphasize the failure of Olimar.
Plays when a Sparklium Springs challenge starts, after the loading screen, and before the "Ready..." message. This unusual-sounding fanfare features bright synthesizer tones reminiscent of those in the main Sparklium Springs theme, playing a sequence of quite diverse chords.
Plays during the short cutscene where Captain Olimar and the Pikmin celebrate having finished a Sparklium Springs challenge. This is a very traditional video game fanfare, featuring brass instruments playing ascending chords and a harp playing glissandi.
