up with vocal exercises before singing. You wouldn’t try running a marathon without stretching, so don’t sing without flexing your vocal cords. Start by sighing to gently stretch your vocal cords while also releasing physical and emotional tension. Sing different notes up and down your vocal range. Stop if you feel your vocal cords straining. Warming up your voice does protect your vocal cords, but it also gives you a chance to relax and gain confidence before singing.  Try warming up with lip trills. Put your lips together and vibrate your lips like you’re humming. Practice this with different notes. Also try arpeggios, such as by singing the “Do Re Mi” tonal scale. You can also choose a sound like “Re” and sing it up and down your vocal range. This exercise is called a siren. Don’t forget to use your entire body! This means maintaining your posture and relaxing your jaw. The more you practice, the more comfortable you will feel singing! Make some time so you can listen to yourself sing. As you hear your own voice, you will likely start caring less if others hear it too. In addition, you get plenty of time to improve your vocal skills, which also leads to more confidence.  Unfortunately, practice doesn't mean perfection. Remember to practice healthy singing, such as good posture and stopping when your vocal cords feel strained. You can sing when you’re doing daily tasks like work or cleaning. This can help make singing feel second nature to you. Love your voice because it is uniquely yours. If you don’t want to hear it, then don’t expect the audience to want to hear it either. Any doubt you feel towards your voice shows on your face and in your body language. You are unlikely to ever feel confident if you are busy doubting your voice.  Many famous singers don’t make it on their voices alone. Artists like Bob Dylan, Ozzy Osbourne, Britney Spears, and Madonna aren’t technically gifted vocalists. No one is a “natural.” Success while singing comes from practice as well as confidence from personality, songwriting, and stage presence. The easiest way to get started singing is to learn more skills. A teacher can guide you and give you feedback along the way. Seek out a vocal teacher in your area. Let them cheer you on as you learn to control and master your voice.  Select a voice teacher that is trained in the genre you wish to perform. Express any concerns you have with your teacher. Let them know that your confidence is an area you want to work on. Teachers can show you how to relax and also find songs that challenge your limits. Singing for a vocal teacher can help you gain confidence, but ask other people to listen to you sing too. This can be difficult, so find a setting that works for you. For instance, invite a few trusted friends or family members to listen to you at home.  Not everyone feels comfortable singing in front of people they know. A karaoke bar or open mic night might be better for you. You could also record yourself singing and share it with your friends and family or post it on social media. Have fun while singing. You can ask for feedback, but focus on getting comfortable on stage so you gain confidence.

Summary:
Warm Practice for at least 15 minutes every day. Accept the sound of your voice even if it seems imperfect. Work with a professional to train your voice. Practice singing in front of family and other small groups.
