Due to his stylistic choices, Jungkook often employs a very unique approach to his singing. He never tries to paint himself as a powerhouse vocalist and uses the natural smoothness of his voice to his advantage. Instead of mixing and belting high, he often sings softly and with a lot of breathiness in tone throughout most of his range. Not only that, but in order to maintain the smoothness and softness in his singing style, he often chooses to sing with his falsetto as opposed to mixing and thus has yet to create the correct muscle memory and development of his mixed voice. For the most part, his mixed voice is quite light in tone and lacks power. His mixing technique relies on a more head-dominant approach and a lot less on his chest voice, which helps him maintain a smooth soft tone overall. Stylistically, it fits exactly the way he intends it to.
However due to him being unable to develop his mixed voice properly and by using too much breathiness in his singing, his larynx tends to be raised much earlier than a more developed tenor would. He actually often mixes quite low and is not known for being a very high belter. Most of the time his mix only goes up to F#4 in their repertoire, only occasionally singing up G4 and G#4. When he sings up to Eb4 and E4, he sounds mostly relaxed and is able to maintain some support, even if it may be shallow and lack depth. However anywhere above E4, his larynx raises and his throat starts to become tight, which results in a mostly whiny tone production. His voice is unable to escape the tension, causing him to sound thin and closed above E4. This can be heard when contrasting the C#4’s in “양화대교“, D4’s in “모릎“, “Fools“, Eb4’s in “See Through“, “뻔한 멜로디” and E4’s in “心中的日月“, with the F4’s in “Coffee“, “Butterfly“, “Miss Right“, F#4’s in “샤방샤방“, “Let Me Know“, “Love is Not Over” “Tomorrow“, “Lost Stars“, G4’s in “See You Again“, “눈, 코, 입“, G#4’s in “I Need U“, “잡아줘” and Bb4’s in “Bang Bang Bang“, “If You” and “Perfect Man.”
