One way to alleviate stage fright is to practice breathing and meditation exercises. Singers who suffer from overwhelming stage fright may face real difficulty as it can interfere with diaphragmatic breathing. Breathing and meditation before the event can be quite effective. Find a quiet place, center yourself, remove any negative thoughts and focus only on your relaxed, deep breathing. When applied successfully, this remedy should allow you to concentrate on the task ahead, instead of your nerves.
Visualization is also a highly effective technique to quell performance anxiety. This can work well if you are able to visualize the performance from start to finish. For some, the act of seeing themselves going through each moment of their performance or speech and ultimately seeing the event culminate in success, allows them to translate the visualization into reality. Climbers are known for visualizing a difficult climb before they begin. Live performance is comparable to climbing as there are no do-overs.
The emotional freedom technique has also been used in eliminating stage fright. It works on anxiety in the way that acupuncture works on physical pain. Specific acupressure points are stimulated to treat emotional imbalances in your body through tapping. Many people have been helped with this technique. Young children can also learn to do this on themselves quite easily.
For some people, stage fright is simply a confidence issue. The best way in these cases to combat the anxiety is to practice tirelessly. The more you practice and get out there, the more confident you become. Even if you have had ten bad performances, if you experience one victory, you can then draw on that memory each time you perform. The more victories you have, the more your stage fright is likely to diminish.
Lastly, seek help until you feel you have conquered your performance fear. Keep trying. If your stage fright is so debilitating that simple exercises or practice have not helped you, seek the help of a professional. The bottom line is don't let stage fright get in the way of your success.
