Ken Hirai's easy-to-sing songs. Songs you want to sing with emotion (21–30)
POP STARHirai Ken
Released on October 26, 2005 as the 23rd single, it became a major hit as the theme song for the Fuji TV drama “Kiken na Aneki” starring Misaki Ito.
Marking the 10th anniversary of Ken Hirai’s debut, the song features a pop, exhilarating melody and luxurious strings.
With a relatively fast tempo and a bouncy rhythm, the melody line keeps driving forward, making it highly recommended for those who love bright, danceable tracks.
The chorus sits quite high, so in addition to using falsetto, it’s crucial to project your voice confidently without hesitation.
Try singing with large, full-body movements, as if sending your voice far into the distance.
Can I call it magic?Hirai Ken
It was written as the theme song for the Panasonic LUMIX GX7 Mark II commercial featuring Haruka Ayase and went on to become a long-running hit.
It’s a quiet, love-filled ballad where the acoustic guitar tones resonate with Ken Hirai’s vocals.
The overall vocal range of the song is F2–B4, and compared to other songs, the high notes aren’t unexpectedly that high, making it a range that seems singable in falsetto.
In fact, Ken Hirai sings it softly in falsetto to create a bittersweet mood, so it’s best to sing with the sensation of releasing a thin stream of sound from the top of your head.
For the low notes in the A section, be sure to raise your eyebrows and take care not to strain your throat.
Before our feelings overlap…Hirai Ken
Rather than imagining a painful future, “Omoigakasanaru Sono Mae ni…” inspires you to stay close to the precious person right in front of you.
Released in 2004, the song was used in a Toyota commercial and as the theme for the drama “Tsumiki Kuzushi Shinso: Ano Kazoku, Sono Ato no Higeki.” With a wide vocal range and a chorus that showcases Ken Hirai’s beautiful, resonant high notes, the difficulty level is on the higher side.
For women, slightly raising the key to adjust the lower notes may work well.
If you have a lower voice, using falsetto to tackle the original key is also recommended.
The song flows at a relaxed pace, so the melody itself is relatively easy to sing.
confessionHirai Ken
Confession is a song that sets dark love to a striking melody.
Released in 2012, it was used as the theme song for the drama W no Higeki (W’s Tragedy).
Its melody is somewhat challenging, with parts that move back and forth between high and low notes.
Overall, it sits in the mid-to-high range, making it easier to sing for women and for men who are comfortable with higher vocals.
Listen closely to the melody and try to capture the pitch changes as you sing.
canvasHirai Ken
Canvas weaves words like painting to capture the faint, bittersweet memories nestled in the precious days of youth.
Released in 2008 as a double A-side single along with “You Are Su-te-ki ♡,” this song was chosen as the theme for the drama Honey and Clover.
Since it spans a relatively wide vocal range, you’ll want to pay some attention to key selection.
Overall, the lyrics flow gently and unhurriedly, making the melody itself easy to sing.
If you’d like to try a song with a broader range, this makes a great entry point.
Missin’ you ～It will break my heart～Hirai Ken
The 2002 release “Missin’ you ~It will break my heart~” is a number that conveys the resolve to live on to someone precious you can no longer meet.
The song flows at an overall relaxed pace, making it easy to sing while savoring the lyrics.
There’s a sudden leap to higher notes toward the end, so if that’s not your strong suit, it might be better to start in a slightly lower key.
English lyrics appear frequently, but because the tempo is laid-back, you can sing them calmly without feeling too much pressure.
one earbud at a timeHirai Ken
The 1995 release “One Earbud Each” paints a lovely scene of sharing earphones with someone you like and listening to the same music.
Although Ken Hirai is often associated with gentle, ballad-like songs, this track is a bright, poppy, and fun number.
Its catchy groove makes it easy to sing along without overthinking.
The key is a bit on the higher side, so it’s comfortable as-is for many women, while men can lower the key a little to enjoy singing it, too.
Immerse yourself in the song’s world, ride the rhythm, and have fun singing!
