[Duet-Worthy Harmony Songs] Songs That Feel Great to Harmonize (1–10)
Miracle of BondsMAN WITH A MISSION×milet
The popular band MAN WITH A MISSION, which enjoys overwhelming support from young men, and the female singer-songwriter milet, known for her Western-style vocal delivery, collaborated on the song “Kizuna no Kiseki.” It’s famous as the theme song for the hit anime Demon Slayer: Kimetsu no Yaiba.
In this piece, the harmony parts are basically sung by milet, but since she sings the line below the main vocal, the song is very easy in terms of vocal range.
The instrumentals are a bit loud, so you might find it hard to pick out the harmony parts, but the parts themselves aren’t difficult—so definitely give it a try.
ringoHata Motohiro × Kusano Masamune
The song “ringo” by Motohiro Hata and Spitz’s vocalist, Masamune Kusano.
Since this piece features Masamune Kusano, many listeners may find the overall key to be on the higher side.
While the pitch is indeed high, the overall vocal range is not particularly wide.
Therefore, if you set it to an appropriate key, it should be singable for anyone.
The harmony parts appear in several places, singing lines above the lead vocal.
For that reason, the harmony singer should be mindful not to make their volume too loud.
Open the doorKanda Sayaka, Tsuda Eiyu
The globally successful hit film Frozen.
This duet version of Love Is an Open Door by Sayaka Kanda and Eisuke Tsuda is one of the popular songs featured in Frozen.
As is common in musical films, this piece is characterized by clear, easy-to-follow harmony parts.
Neither the lead nor the harmony lines are particularly difficult, and since it’s a male–female duet, there’s less risk of being thrown off by your partner’s voice.
Give it a try!
[Duet Harmony Songs] Songs That Feel Great to Harmonize (11–20)
Ah, what a relief.Hana＊Hana
This was Hana*Hana’s major debut single, released in 2000.
Hana*Hana is a female duo whose vocal abilities are highly acclaimed.
Even on this debut single, they showcase wonderfully crafted choral work.
The chorus arrangement is a relatively simple two-part harmony, so it should be fairly approachable and enjoyable for everyone to try harmonizing at karaoke.
For the song we’re introducing this time, “Aa Yokatta,” the part you need to pay the most attention to when singing it at karaoke isn’t the chorus, but rather the sections where the two singers trade lines like a call-and-response.
Pay close attention to the sense of rhythm and groove, and aim to sing it with style!
My WayDef Tech
Def Tech’s classic song “My Way.” If you were born in the Heisei era, when you hear “a harmony-driven track,” this is probably the first song that comes to mind.
One reason it’s so easy to sing is its narrow vocal range.
While there are other songs with a limited range for the lead vocal, this track also keeps the harmony parts relatively narrow.
That makes it perfect for people who struggle with higher notes.
Just note that there are many rap-style sections, so be sure to lock into the flow as you sing.
green leavesHata Motohiro × TOMOO
Singer-songwriter TOMOO has been gaining attention since the 2020s and is viewed within the industry as an artist poised for an even bigger breakthrough.
A collaboration between TOMOO and popular singer-songwriter Motohiro Hata, Aoba is the result.
Crafted as a classic J-pop ballad, the song features a very singable vocal line.
The female harmony part takes the lower chorus, so even those who struggle with high notes can sing it comfortably.
COLORSFLOW
I think FLOW is also famous for having twin vocals with lots of harmonies.
They do a lot of anime songs—are there any you all know? In this song, COLORS, KEIGO basically sings the main melody and KOHSHI sings the harmony parts.
From the B-melody they sing in unison an octave apart, then from the chorus there’s a lower harmony—going back and forth like that feels great to sing and really makes the song build up! This applies to any song, but if the lower harmony ends up louder than the main vocal, the balance gets thrown off and it sounds odd, so I recommend singing lightly with the image of supporting the lead.
It’s one of FLOW’s staple tracks, so definitely give it a try!
