Singing is the art of performing. A good singer is a good musician (he sounds good and sings the right notes) and a good performer (he's hot and interesting to watch). There is, in fact, a relationship between performing well and singing well; These skills depend on each other.
Is there a secret formula for becoming a great singer? No, but cultivating these five skills brings out both musical and performance abilities. Practice these exercises, and you'll be able to sing accurately and put on a good show.
good ear
singer needs to sing in tune! For those who weren't born with sensitive hearing skills (also known as a musical ear), learning to match pitch consistently is an important first step to singing. Working with a voice teacher on auditory skills exercises, and practicing those exercises at home, helps. Technology, such as pitch recognition apps, is helping at-home practice for students who aren't yet sure if they're singing the right pitches.
breathing power
The more support you have, the more phrases you can sing and the easier it will be for you. Developing a strong base of breathing support by learning about the body's breathing systems and doing exercises related to the breath allows you to sing those newly tuned songs with ease and softness.
relax
Have you ever seen someone with a rigid body (shoulders, tense)? It's very stressful for the audience, not just the performer. Learning to relax your body—particularly parts directly related to singing such as your jaw, tongue, and neck—in performance situations is an essential skill for singers. Practice singing in front of a mirror, noting what is happening. When you hit a high note, do you strain your shoulders and neck? See what happens if you don't. Does it look better?...
balance
While you need to relax in singing, you also can't be a blessing on the ground. Fans take artists with a strong attitude more seriously. Practice standing comfortably and straight, without crossing your arms or leaning to one side. Balance your weight across your feet, over your pelvis, and all over your spine.
If you're playing another instrument while singing, spend some time finding a good position for your body while you're doing it. Are you leaning too far forward to look at your guitar strings, for example? What do you think of this sound?
Self-confidence
If you've ever watched an amazing singer, you've probably noticed that you look quite confident. Maintaining a relaxed, correct posture is a big part of this: Humans score a relaxed, open posture as a sign of confidence, and standing this way can make you more confident, too. Practicing auditory skills, breathing support, and other elements of good singing also helps you feel more confident in your abilities.
Got pre-show misinformation? Do some slow breathing exercises. Eat bananas (they help the brain produce serotonin). Try holding a power pose, such as "Wonder Woman Pose" for two minutes (this also raises dopamine levels in the brain). Then get out there and have a great time!
