A “partner song” refers to a combination of songs that share the same or similar chord progressions and create beautiful harmony when sung or performed simultaneously.

Famous examples include pairings of children’s songs and school songs like “Donguri Korokoro” and “Yuyake Koyake.” In recent years, however, popular creators have released duet videos that combine current hit songs, which has become a hot topic.

In this article, we’ll introduce a variety of partner songs that go beyond conventional categories.

Try incorporating them into singing-based recreational activities, challenge yourself at karaoke, and enjoy these exquisite combinations in many different ways.

Isn’t it surprising that these two songs by Mrs.

GREEN APPLE and Vaundy exist as partner pieces? “Ao to Natsu” is a refreshing youth anthem that evokes summer sunshine and a vivid blue sky.

“Kaijuu no Hanauta” is a fast-paced number about trying to reclaim an honest heart while comparing your past and present self.

Both songs are undeniable mega-hits.

orion × COSMOSYonezu Kenshi × Mimasu

[Too Emotional Warning] orion/Kenshi Yonezu × COSMOS/Choir Song 2024 ver.
orion × COSMOSYonezu Kenshi × Mimasu

By pairing Kenshi Yonezu’s signature song “orion” with the choral piece “COSMOS” as partner songs, you can create a compelling sonority that differs from singing each one on its own.

Released in 2017, Kenshi Yonezu’s “orion” calls for delicately conveying feelings through the vocals, bringing out the song’s lyrics of love—tender yet powerful.

For the choral piece “COSMOS,” understanding the meaning of the lyrics and singing with an unforced, natural tone will help communicate the piece’s appeal more effectively.

When combining them, it’s best to sing while listening to each other so the resonance blends, without getting thrown off by the other part.

Koinobori × Height Comparison

These two songs are known to every Japanese person.

They’re built on similar harmonies, so they match well, but that also makes it easy for one melody to pull you into the other.

The lyrics to Koinobori were written by Miyako Kondo, also known for the songs Tulip and Pony.

Her lyrics, which draw out the parental love symbolized by carp streamers, are timeless.

Sekurabe is a children’s song selected for the “100 Best Japanese Songs.” It would be great to try singing them as partner songs, and simply getting everyone together to sing children’s songs would make for a lovely time.

This Wonderful World × Twinkle, Twinkle, Little Star

Although What a Wonderful World has a jazzy, mature vibe and Twinkle, Twinkle, Little Star is hugely popular with children—and their styles are completely different—when you match their tempos and sing them together, a beautiful harmony emerges.

What a Wonderful World is a song about human connection and hope for the future.

Twinkle, Twinkle, Little Star, as its title suggests, depicts the twinkling stars in the night sky and is beloved by children.

Try singing the tender song and the cute one together to experience how well they pair.

Donguri Korokoro × Yuuyake Koyake

Partner song “Yuyake Koyake + Donguri Korokoro” Sing-along café at the 30th Aichi Utagoe Network
Donguri Korokoro × Yuuyake Koyake

Both are children’s songs that have been loved since the Taisho era and are still sung today, especially by kids! At first glance, you might think that because “Donguri Korokoro” is rhythmic, it wouldn’t fit well with the beautiful melody of “Yuuyake Koyake.” But both are designed so the lyrics fit within a 4/4 beat, so when you combine them, they line up perfectly! It’s kind of mysterious, isn’t it? This is just my personal opinion, but when sung simultaneously, the more relaxed rhythm of “Yuuyake Koyake” might be easier to get pulled off by.

I think it will go well if you practice by clapping your hands or using a metronome!

Annie Laurie × Londonderry

Partner song Annie Laurie & Londonderry
Annie Laurie × Londonderry

Even if you don’t know the title, as soon as you hear it you’ll say “I know this!”—that’s Annie Laurie, one of Scotland’s representative folk songs.

Its gentle melody, evocative of vast lands and a meandering river, is superbly relaxing.

Londonderry Air is a famous Irish folk tune, well known as a practice piece for piano and violin.

These two songs are linked in their praise of the natural rhythms of life that breathe in the cold northern lands, and when sung together they create an exceptionally beautiful harmony.

These two songs are huge hits at karaoke.

“Gurenge,” with its restrained A-melody, pre-chorus break, and explosive, crowd-pleasing chorus, is outstanding for pumping up the room! As for “Senbonzakura,” it’s no exaggeration to call it a monumental masterpiece beloved by every Vocaloid producer—so influential it can’t be contained within the Vocaloid world and has been covered by dozens of artists.

Sing these songs together, and there’s no way the energy won’t soar.
