remain ~ The Key to the HeartKoyanagi Yuki8rank/position

[Official] Yuki Koyanagi “remain ~ Key to the Heart” (MV) YUKI KOYANAGI / remain - Kokoro no Kagi (10th single)

It seems this was the theme song for the TBS drama “How Many Years Will You Take a Break from Love?” and was performed at the 52nd NHK Kouhaku Uta Gassen.

The arrangement highlights Yuki Koyanagi’s signature combination of a rich tone and delicate vibrato, so it’s highly recommended as a practice piece for vibrato.

The overall vocal range is G3–D5, and the song builds toward the latter half.

Since there are many sustained notes, singing with a lingering resonance will make it easier to apply vibrato.

Also, while Yuki Koyanagi’s voice is powerful, try not to overstrain; use ample breath and aim to resonate through your body when you produce sound.

Yuki Koyanagi – Vow

Yuki Koyanagi’s 20th single, released in October 2006.

Yuki Koyanagi is known for her strikingly powerful mid-to-high range, which can likely be attributed to her use of a high-pressure mixed voice with minimal breath leakage.

Her tone is also notable for its edgy quality and rich overtones across the entire range.

Thanks to this, her gentle high-tone falsetto really comes to life.

The connection to what seems to be a relatively low natural chest voice is also exceptionally smooth and well-executed.
