Once you have mastered your technique and start to feel and hear a difference in the way you sing, it will instantly give you the confidence to take things to 'the next level'.
If you're looking to improve your singing ability for auditions for example, you'll know it takes more than just sounding great. Your performance has a genuine physical effect on your sound as well as your stage presence. Just smiling for example, or changing your facial expressions can completely alter the type of sound you produce, but it really takes guts to take yourself out of your comfort zone, and can sometimes feel completely un-natural. Once you have the basics down you can really have fun with it! It doesn't matter what style you sing, your body language and presence will effect the mood you're trying to create and it takes practice to get this right. A performer needs to be sensitive enough to understand and really know their audience, and they will gradually learn how to adjust and tweak performances accordingly. Mostly, singing is about being in touch with your feelings, being vulnerable, taking chances and expressing those feelings with an open heart. Sometimes it doesn't pan out of course, but you'll soon learn what works and what doesn't. This is how we evolve from being just a singer, into to a true performer who is able to hold their audience and bring that something special!
