I have already been singing professionally for years. Why should I start taking lessons now?
While many professional singers have natural talent, it is also common for them to have poor technique. Singers with poor technique often run into difficulties keeping up with the vocal demands of their schedules, and sometimes have to cancel concerts or even tours as a result of vocal fatigue, strain or injury.
Regardless of what point you are at in your career, proper technique can always be learned and applied. In addition to learning healthy singing habits and good vocal care, vocal lessons can help a professional singer gain endurance and stamina so that he or she may continue to perform night after night without running into vocal problems. An experienced instructor can also help the singer to naturally and safely repair any damage to the vocal apparatus without the need for surgery.
