[Partner Song] Sing two different songs at the same time! Children's songs & latest hits (1–10)
Moon over the Ruined Castle × Mary Had a Little Lamb
Both songs are ones typically sung in kindergarten or elementary school, so you can probably sing them even without lyric sheets.
They also don’t require karaoke, so let’s just count in and sing them all the way through.
“Kōjō no Tsuki” is a work by Rentarō Taki, one of Japan’s most celebrated composers—a classic from the Shōwa era that carries a distinctly Japanese sense of melancholy.
“Mary Had a Little Lamb” is considered a nursery rhyme of American origin.
The darker arrangement of “Mary Had a Little Lamb” may feel odd at first, but as you sing it as a partner song, you’ll find you strangely get used to it!
Banquet Song × A Little Love Songtuki. × MONGOL800
High school artist tiki.
, whose debut song surpassed 300 million total streams at a record-young age.
Their appearance in the 2024 Kohaku Uta Gassen—shown only in silhouette and from behind—also became a hot topic.
It’s astonishing that tuki.
’s clear-voiced “Bansanka” pairs as a partner song with MONGOL800’s ever-energetic “Chiisana Koi no Uta.” There are videos where these two songs are sung simultaneously, so give them a watch first! It might be fun to try the challenge with like-minded friends, too.
Hamabe no Uta × Home on the Range
I think everyone has songs where they know the melody but only vaguely remember the lyrics.
“Hamabe no Uta” might be a prime example—you know the first verse, but then… The scene on the boat in the film Twenty-Four Eyes, where the song begins a cappella, was truly moving.
“Home on the Range” is an American folk song.
It was also featured on NHK’s Minna no Uta, and Akiko Yano has even covered it.
Listening to the beautiful, cat’s cradle–like interweaving of these two pieces is sure to leave you entranced.
Blue and Summer × Monster's Flower SongMrs. GREEN APPLE × Vaundy
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.
In the video, the two masterpieces are beautifully mixed with stunning vocals, so be sure to check it out for inspiration!
Small World × If You're Happy and You Know It
“It’s a Small World,” beloved as an iconic Disney theme song, and “If You’re Happy and You Know It,” based on an American folk tune, share similar styles and worlds, making them a perfect partner-song match! They’re fun for anyone to sing, from children to adults.
Since “It’s a Small World” has fewer words per measure, it might be easier to get pulled along by your partner.
Try singing them as a parent-child duo, and they’re also great for activities in childcare or senior care facilities—give it a go!
orion × COSMOSKenshi Yonezu × 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.
