Welcome to the world of "Vocalo Jazz" [VOCAJAZZ]

One Room, All That JazzDATEKEN

One Room, All That Jazz! – DATEKEN feat. Miku Hatsune / One Room, All That Jazz – DATEKEN feat. Hatsune Miku

It’s a track with a mature jazz vibe.

The piano’s quiet, beautiful tone and the simple yet captivating lyrics make you want to listen while tilting a glass filled with something fragrant as the night grows late.

It’s also recommended for those times when your heart feels a little tired.

I really, really, really hate it.Dennoko-P

[VOCALOID] DAI DAI DAI KIRAI / DAI DAI DAI KIRAI (known as “I hate you”)

A Vocaloid track with a uniquely soft sound and a mysterious atmosphere.

It’s the debut song by Den-no-ko P, a Vocaloid producer known for a distinctive, independent musical style, released in 2014.

While it’s a fast-paced, jazz-tinged piece, its appeal lies in genre-defying arrangements—like the noisy timbres that surface at key moments and choral work featuring various VOCALOIDs.

Listen once, and you might find it hard to escape Den-no-ko P’s world.

Glass Threads / feat. Ken

Perhaps because of its simple sound, it feels like the music seeps deep into your chest.

It’s a song by Tota Kasamura, a well-regarded Vocaloid producer known for choral pieces, released in 2019.

The thick, warm singing voice of the VOCALOID library Ken pairs beautifully with the soundscape of just piano and drums.

The lyrics portray the heartrending feelings of a protagonist longing for love.

As you listen, your heart grows increasingly tight—it’s a sad yet beautiful Vocaloid track.

Queen of the Nightscrew-type

[Yukari Yuzuki] Queen of the Night [Original]

It’s a mature world that’s both sexy and bittersweet—the contrast is irresistible.

Composed by Nejishiki, the Vocaloid producer also known for the hit “Freedom Lolita,” the track was released in 2016.

It’s a full-fledged jazz number with a sense of glamour and exceptionally high quality.

The sound design matches the lyrics perfectly and never gets old—you’ll want to play it on repeat.

Incidentally, this is a self-cover using Vocaloid of a song originally provided to the singer Senra.

Someone To You / flower (Dare Demo Nai / flower)

How about a jazz number with a downbeat vibe? It’s a track by Δ, a Vocaloid producer also known as the creator of “You’re Not Wrong,” released in 2018.

From the piano timbre that sounds like the keys are being struck hard to the rough, distorted sonic image, it’s incredibly cool.

The lyrics feel as if they directly portray the protagonist’s turmoil over their own existence.

It’s a highly addictive work that stands apart from mainstream jazz.

Club = Majestynyanyannya

Club = Majesty / nyanyannya (The Great Genius-P) feat. Kagamine Len

It’s an ultra high-speed song.

It’s so fast that if you could catch every word on the first listen, that would be amazing! In a way, it makes full use of Vocaloid’s strengths.

But precisely because of that, I can’t help but think how incredibly good it would feel to be able to sing it flawlessly—or to perform it.

[Hatsune Miku] Gossip [OSTER project]

Listening to this glossy, powerful track, I couldn’t help but imagine a scene from a movie: a woman singing in a corner of a restaurant bar, accompanied by a grand piano.

It’s a sexy, cool song with a great tempo that makes you want to start stepping to the beat.
