[Harmony Songs for Duets] Songs that feel great to harmonize

When you sing harmony songs at karaoke or live shows, that satisfying moment when your part blends perfectly with your partner’s feels so good, doesn’t it? But when you actually try it, many people may feel things like: “I can’t tell which is the lead and which is the harmony,” “I keep getting thrown off,” or “It’s hard to stay on pitch.” So this time, we’ve picked out songs where the harmony parts are clearly divided and easy to sing, as well as songs that feel great when you harmonize on the chorus! We’ve gathered everything from classic Showa-era hits to the latest tracks, so enjoy harmonizing with your karaoke buddies or bandmates!

[Harmony Songs to Sing as a Duet] Songs That Feel Great to Harmonize (71–80)

Since this song was used as the theme for TBS’s Tuesday drama “Taigan no Kaji – This Is My Way of Life!,” I think many of you will find it familiar.

With Rikon Densetsu, harmonies tend to come in right at the key moments, and that selective use feels very band-like.

Most of the harmonizing happens on word endings, often as a lower harmony, giving the vocals a gentle feel.

In the last chorus, they go all-out with octave-unison lines and harmonies, which really brings the song’s atmosphere across.

The range isn’t too wide either, so it should be an easy challenge even for those who aren’t used to harmonizing.

presentJITTERIN’JINN

This was Jitterin’ Jinn’s second single, released on February 14, 1990.

Speaking of Jitterin’ Jinn, they were one of the representative bands of the so-called beat-punk genre, which was at the center of the band boom in the ’90s.

Many of their songs feature very straightforward, easy-to-grasp melodies and catchy lyrics, and “Present” is one of those hits.

Starting from the A-melodic section of the second chorus, a male vocal “ji-hamo” (syllable-by-syllable harmony) comes in.

In the original, the male chorus part is a lower harmony, but if you’re singing this at karaoke, since it’s a male-female harmony song, I think having men and women sing in unison can still make it sound “authentic.” Enjoy!

This is THE ALFEE’s 17th single, released in January 1984.

Following their previous smash hit “Mary Ann,” which marked a complete shift from their early folk style to a rock-forward sound, this single again features Masaru Sakurai on lead vocals.

THE ALFEE is known for having all three members capable of taking the lead and for their acclaimed choral work.

While many of their songs include very complex chorus arrangements, this track uses a classic rock approach: the chorus comes in only on the signature phrases of the refrain.

To be honest, the harmonizing element might feel a bit thin here.

Still, it’s one of the best songs for everyone to sing the hook together and get hyped, so don’t worry too much about perfection—just have fun singing it!

This is Kobukuro’s 9th digital-only single, released in July 2022.

Incidentally, as a CD single it is their 34th, released in October of the same year.

It was reportedly created as the official theme song for the Osaka-Kansai Expo to be held in 2025.

While Kobukuro are well known for their harmony work, this song features a vocal arrangement designed to stand on its own with a large-group unison performance.

So by all means, enjoy singing it together with all your friends on the spot.

In sections like the A-melody where harmonies appear, the parts are written to harmonize a third above the main melody—give that a try as well.

Sukima Switch’s harmonies are basically the “lower harmony” in my mind.

The upper harmony is easy to grasp, but isn’t the lower harmony kind of hard to find by ear? Still, their two voices balance so well—I love it, and it always makes me want to harmonize! Especially in this song, the lower harmony right after the final chorus line of the hook feels amazing when it locks in, so that’s my top recommendation.

I think it’s fine to sing with about the same volume as Ohashi! The key with lower harmony is to support firmly without sticking out more than the lead vocal, so it might be tough to pitch at first, but do your best not to get pulled toward the main melody!

This is the theme song for the Sunday drama airing in the April 2025 season, “Dame Mane! – Managing a Hopeless Talent –.” As with most dramas, the timing when the theme song kicks in near the end is just perfect, and since this song has no intro, I was moved every time by vocalist Mayu Tanikinu’s gentle voice.

As you listen, the unison one octave below in the chorus really stands out.

This serves as an important foundation in the low end! The way the chorus comes in after the C section with call-and-response is also lovely, so I’d love to line up the timing and sing that part too.

Basically, the harmony is sung one octave below, so it might be too low for some women, but be careful not to strain your throat.

twofold forgettingKobukuro

Kobukuro’s 33rd single, released on July 7, 2021.

By the way, the title is pronounced “Ryōbō.” Since their debut, Kobukuro—a duo of Shunsuke Kuroda and Kentarō Kobuchi—has been highly praised for their harmony work, and that well-regarded harmonization is alive and well in this song, letting you enjoy beautifully crafted chorus parts.

Because they’re known for their choral work, some people might hesitate to try harmonizing this song at karaoke, but the chorus arrangement isn’t actually that complicated, so there’s nothing to fear! Definitely give it a try.

Just be careful not to make your vocals too edgy or forceful, as that could spoil the song’s charm.

Aim to sing as gently and softly as possible.
