UV's Lee Chang-sub's 'Illegal Singing Class', Demonstrating Vocalization Stages from Chest Voice to High Voice

Lee Chang-sub, a member of the group UV, presented an unusual lesson scene themed around vocalization methods.

In the video released on the YouTube channel 'UV Recording Studio', the process of Lee Chang-sub teaching the cast members how to use their voices for singing was captured. At the beginning of the video, the cast members showed interest in Lee Chang-sub's way of making sounds and sought advice to become vocal masters. The cast members expressed their desire to learn Lee Chang-sub's way of using his voice, stating that in this country, only Nam-a, Ha Dong-kyun, and Jeong Seong-a have perfectly mastered vocalization. In response, Lee Chang-sub introduced himself as an 'academy director' who runs an academy at Suwon Station and began his full explanation.

From chest voice to high voice, step-by-step vocalization demonstration

Lee Chang-sub explained the major stages of vocalization, such as chest voice, nasal voice, and high voice, by implementing them directly with sound. Lee Chang-sub emphasized how to make sounds naturally, just like when speaking, explaining that one only needs to place the pitch accurately. In the video, Lee Chang-sub showed the differences between each vocalization by utilizing methods such as making sounds without opening his mouth. When explaining chest voice, he emphasized that it is a sound coming from the chest and mentioned the proportion of the bass, then proceeded to demonstrate the nasal voice, which utilizes the nose, and the even higher stage, the high voice. During this process, he was seen visually distinguishing the differences between head voice, nasal voice, and chest voice using gestures like pointing fingers.

In particular, to explain the high voice, Lee Chang-sub showed a practice method of making continuous sounds while lowering his posture and sticking out his tongue, similar to how actual athletes do. Lee Chang-sub continued the learning process, saying, "Once you reach this level, you can move on to the next stage with just a little bit of instruction." During this process, the cast members reacted to the vocalization stages shown by Lee Chang-sub, appearing to learn by feeling the sensation of the sound being transmitted toward the head.

A finale that confirmed Lee Chang-sub's singing skills

After the vocalization explanation was completed, Lee Chang-sub proved his skills by singing himself. Lee Chang-sub continued singing, delivering the lyrics, "Because of what I learned, my greedy hearts that disappear in an instant, through those passing clouds," and the cast members watching this gave a positive reaction to Lee Chang-sub's singing ability, saying, "You're good."
