Karaoke songs you can enjoy singing in your natural voice without changing the key

One of the best things about enjoying karaoke is being able to sing out loud in your natural voice, right? But there are plenty of songs with keys that are too high to sing, or that can hurt your throat if you force them.

To solve those problems, this article introduces a wide range of songs you can sing comfortably in your natural voice! Whether you’re male or female, these are songs you can enjoy singing in the original key and finish feeling great, so be sure to use this as a reference when choosing your next karaoke songs!

Women (21–30)

HY’s classic song “366 Days.” This track is beloved across a wide range of ages, from younger listeners up to people in their 40s.

It’s a karaoke staple, so many of you have probably sung it at least once.

Its vocal range spans from mid1 E to hi G#, which is very wide, making it a bit challenging to sing without adjusting the key.

However, apart from the extremely high falsetto ad-libs in the final chorus, if you can handle the light falsetto in the B section, you can try arranging the ad-lib part in your own way.

Doing so will significantly narrow the required range, which is recommended.

Among Aimyon’s songs, “Harunohi” is particularly easy to sing in the original key.

I even had a male student who tackled it in the original key! The song itself is a bit long at about five and a half minutes, and once the singing starts it’s nonstop, but it’s widely known across all ages and genders, so it works well for karaoke.

That nonstop singing part can be a bit tough.

If you’re mindful of your breath timing and where to place accents, it becomes easier to sing without running out of breath.

Also, since the structure builds sequentially—A verse → B verse → chorus—it’s important to consciously add a little more energy to each phrase.

Right before the chorus, the high notes are the key: imagine sprinting up a staircase and project your voice firmly.

Give it a try!

Chanmina’s Harenchi is sung mostly in a lower register, giving off a mature, sultry vibe.

Just when you think it will end quietly, the last chorus turns emotional and shifts into a slightly higher range.

I think that switch is really important.

There’s also a rap section in the middle, so that part needs practice too.

My students practiced the rap section a lot as well.

When the rap really lands, it feels great to sing and sounds very cool.

For the rap melody, it seems easy to memorize if you first focus on humming or using a neutral syllable like “la” instead of the lyrics.

Try singing without forcing or pushing your voice!

Lingering Snowiruka

Iruka’s song “Nagori Yuki,” long cherished as a classic in Japan.

Released in 1974, it’s rooted in the then-popular folk music genre, and while it’s moving, it retains a certain folk-like poignancy.

It was originally a Kaguyahime song, but many people are probably more familiar with Iruka’s cover.

The song’s vocal range is relatively narrow, from mid1 D to mid2 G.

With the highest note at mid2 G, few should find it difficult to sing in the original key.

The A verse is somewhat spoken in style, so there are slightly fewer breakpoints, but as long as you don’t push your voice too hard, it shouldn’t be a problem.

Unchanging ThingsOku Hanako

Okuda Hanako’s classic song “Kawaranai Mono” (“The Unchanging”).

Released in 2006, it’s well known as an insert song for the film The Girl Who Leapt Through Time, and its orthodox J-pop ballad style has garnered support from many listeners.

The song’s vocal range spans mid2 A# to hi C#, which is a very comfortable and relatively narrow range for female singers.

While the final chorus features a solid development, there’s no key change, so you’re unlikely to struggle with vocal height.

In terms of range, pitch movement, and rhythm, it’s an easy song overall—definitely give it a try.

Female (31–40)

Anri’s hit number “Listening to Olivia.” Thanks to the recent revival boom, it has gained some recognition among younger generations as well.

The song was released in 1978 and became a long-running hit with its distinctive musical style that blends New Music and kayōkyoku.

Its vocal range is somewhat narrow at mid1 G# to high C, and the pitch movement isn’t very drastic.

It’s slightly high for men and slightly low for women, making it highly recommended as a song that can be sung in the original key regardless of gender.

Noriko Sakai, the idol singer affectionately known as Nori-P.

Despite past scandals, her cute songs are still loved by people of her generation.

Among her tracks, the one I especially recommend is Aoi Usagi (Blue Rabbit).

This song spans a fairly wide vocal range from mid1 A to high C, but since the highest note is only a high C, the high phrases aren’t particularly hard to sing.

Considering when it was released, it’s likely to be sung by those who’ve gained some years since then, so you may find that even the lower phrases, including the lowest notes, are easier to produce than you might expect.
