'Directing changes the moment you see your vocal cords.'
I visited an otolaryngologist with a vocal major student who was about to finish their debut showcase and album recording. Although this friend was known as a "member who sings well" for effortlessly handling high notes, their voice sounded thin and unstable in the lower register.
This coincided with a period of poor vocal condition, making it difficult to distinguish whether the issue stemmed from physical condition or vocal habits.
Direct observation through laryngoscopy and vocal fold vibration testing revealed that the low notes were slightly different from expectations. As the pitch descended, the vocal folds appeared to open while the cartilage inside the larynx twisted. The image on the screen looked like someone twisting a thin aluminum can sideways until it crumpled. This provided grounds to reevaluate the phenomenon I had assumed was simply "poor voice quality preventing low notes," now considering vocal habits as well.
Seeing one's own vocal cords directly was also a new experience for the vocalist. After confirming vocal habits on screen—habits that were difficult to fully grasp through verbal explanation—their attitude toward acceptance changed. With additional explanations from an otolaryngologist based on the examination images, they could finally connect the sounds they had only heard with their body's movements. This made the starting point of training significantly more concrete.
Individual lessons began after the examination. Although this vocalist had undergone long-term training at an entertainment company, our first individual lesson started not by adding new techniques but by re-examining falsetto and low notes.
Why start with falsetto and low notes for a vocalist who skillfully handles high registers? In practical music, falsetto is not merely a substitute for high notes that are difficult to produce with chest voice. Shifting between chest voice and falsetto to alter tone color and texture is itself an important expressive technique. Recently, vocal textures resembling casual speech or humming have been actively used in popular music. As "bedroom sound" has become familiar, vocal charm in directions other than powerfully projecting high notes has also gained importance. One such aspect is how skillfully and attractively falsetto can be utilized.
Another key focus was the relationship between high notes and mid-to-low registers. While guiding vocalists, I often observe cases where high notes sound excellent but different vocal patterns interfere in the mid-to-low range. This vocalist similarly had unstable mid and low notes but possessed good vocal quality in the high register.
Therefore, rather than repeatedly practicing only the problematic low notes, we adopted a method of descending from the well-established high notes to mid and low registers. By maintaining the sensory experience of sound production in the high range while lowering the pitch, unnecessary tension patterns in the low notes decreased, resulting in overall vocal refinement. Vocalization does not necessarily have to be built only from low to high pitches. If certain ranges are already functioning well, answers can be found there and connected in the opposite direction.
This also invites reconsideration of the meaning of basic vocalization. Practical music never demands only neat and perfect sounds. It may involve rough scraping, heavy breath mixing, or intentional sound distortion. What matters is not just whether one can produce such sounds, but whether they can be selectively used when needed and return to a comfortable sound afterward. For this purpose, basic vocalization serves as a default value. Fundamentals are not rules that limit expression but foundations that expand expressive options.
This day's experience also demonstrated that "vocal condition" and "vocal habits" should not be treated as the same issue. Professionals who use their voices as a livelihood need to distinguish whether current vocal cord conditions or recurring problems stem from physical state or vocal habits.
Here, hospitals and training provide different types of information.
Otolaryngologists confirm the medical condition of vocal cords using examination equipment. Vocal trainers address pitch ranges, vocal patterns, and singing habits while listening to actual sounds. Seeing one's vocal cords at a hospital does not automatically change singing habits, nor can a trainer determine the medical state of vocal cords simply by listening to them for a long time. Distinguishing the roles of these two fields helps more accurately understand professional vocalists' voices.
Vocal management relies less on new tricks and more on already known fundamentals.
These include sufficient sleep, hydration, correcting overused vocal techniques, warming up before singing and cooling down before bed, and adjusting vocal usage volume ahead of performances or recordings. While these may seem too obvious to notice, for professionals who use their voices as a livelihood, consistently adhering to these fundamentals is management itself.
In vocal training, learning to listen to one's own voice is crucial. However, if one must stand on stage professionally for an extended period, understanding how that sound is produced within one's body is equally necessary. The technique of creating good sound and the management required to sustain it over time must go hand in hand.
