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!

Male (41–50)

Sign of Lovesupittsu

It makes you want to imitate those unadorned vocals! This track by Spitz, a rock band that’s been at the forefront of the Japanese music scene for many years, was included on their 1999 album “Ka-Cho-Fu-Getsu.” It was originally written for the duo PUFFY.

The relaxed, easygoing guitar rock sound is fantastic—you’ll want to clap along and get into the groove! The vocal range should be easy for most women, and it’s quite approachable for men too.

It also sounds like it would be fun as a duet!

Male (51–60)

Formed in 2004, back number is a rock band that has remained at the forefront to this day.

While their songs often feature abundant falsetto and many high-note phrases, there are also tracks suited for lower male voices.

One such song is Suiheisen.

Although this piece spans a slightly wide range (mid1 D to hi C), the highest chest voice note is mid2 G, so as long as you can handle the falsetto parts, it should be relatively easy for lower-voiced male singers.

It’s also recommended to intentionally raise the key for the falsetto sections to make them easier to sing.

DOES – Overcast Sky / THE FIRST TAKE

Released on June 18, 2008, it’s the fifth opening theme song for the TV anime Gintama.

At just three minutes long and with a repeating melody, it’s extremely easy to remember.

I think it’ll be a big hit with fans of anime songs, rock, and bands! The vocal range is C3–F4, which is comfortably within the range for many male singers.

If you’re good with high notes, you might find it a bit lacking, so try raising the key when you sing! By the way, songs with a narrow range that are easy to sing can sometimes feel a bit dull and less enjoyable.

In those cases, try adding exaggerated dynamics to each phrase, emphasizing the initial accents, or making small tweaks to build excitement.

If you avoid sounding too flat and learn to sing it with a pleasant flow, you’ll enjoy it even more!

Wine Red Heartanzenchitai

Anzen Chitai - Wine Red no Kokoro (Wine-Red Heart)

With lyrics by Yosui Inoue and music by Koji Tamaki, this is one of Anzenchitai’s signature songs.

Many people born in the early Heisei era or the Showa era have probably sung it.

Since it’s sung in a generally calm tone and range, it’s easy to sing at karaoke.

There are a few spots where the melody rises.

Belting those parts can sound cool, and singing in a composed tone like Tamaki does also gives it a tasteful charm.

From the high point of the chorus to where the melody drops slightly, the pitch can be tricky, so it may help to focus on the lower notes and sing them carefully.

It’s a recommended song when you want to deliver a gentle, heartfelt performance.

SMILE ~Like a Clear, Sunny Sky~Kuwata Keisuke

Keisuke Kuwata “SMILE ~Like a Clear Blue Sky~” Commercial Broadcasters Official Special Movie (Joint Commercial Broadcasters Project ‘Let’s Do It Together’ Support Song)

It’s a cheer song imbued with the message, “No matter the era, don’t forget to smile and keep looking forward.” It was used as the theme song for the 69th NHK Kouhaku Uta Gassen and also as the theme music for Nippon TV’s broadcasts of the Tokyo Olympic and Paralympic Games.

As you listen, you’ll notice the melody stays relatively low from start to finish, so it’s recommended for singers who are strong in the low to mid-high range.

In the low notes, be careful not to let your voice get muffled so you can maintain good balance.

Rather than forcing your voice, make sure to use your breath well as you sing.

Also, lifting your facial muscles and eyebrows will brighten the tone of your voice, making it less likely to get muffled and easier to sing.

Singing with a smile versus with a blank expression gives a completely different impression, so be sure to try it.

Among vocal training students who struggle with high notes, a very common comment is, “Because my voice is low, Masaharu Fukuyama’s songs are easy to sing!” In fact, Fukuyama’s songs often have a wide low range and don’t feature many excessively high notes, so there are plenty of songs you can sing in the original key.

However, one caveat is that if you sing the low notes with your throat as if you’re speaking, even a comfortable range can feel strenuous.

It’s important to vibrate the vocal cords at every pitch, so place your hand in the hollow between your collarbones and try singing while checking that your vocal cords are properly vibrating.

Also, when producing sound, aim your voice as if projecting to a distant point; this helps engage the vocal cords rather than the throat.

Instead of mumbling up close, it’s best to sing as clearly and crisply as possible.

It was Sukima Switch’s second single, released in March 2004.

It landed many tie-ins, including being an insert song for the film “Rough” and the theme song for Night 3 of Fuji TV’s four-night drama series “Sotsu Uta.” Throughout the entire piece, you can feel a warm, easygoing atmosphere—truly one of the Heisei era’s gentle masterpieces.

The vocal melody doesn’t require straining for high notes, so many people should be able to enjoy singing it without changing the key.

Just pay attention to the brief falsetto part that appears for a moment in the chorus.
