Vocal warm ups are vital to longevity, for vocal health, for your singing future, achieving healthy tone, technique, no tension etc
Posture is key for singing. Be aware of how you’re carrying yourself. Being hunched over will lose energy and your breathing will become shallower. You want to have a lifted rib cage. Think about “Noble/Royalty” and posture accordingly. Head up but not pushed forward or backwards. Stand with feet slightly apart and ground yourself well.
Hydration – try to drink half of your body weight (lbs) in ounces. Tea is also great with honey and lemon. If you are on the verge of having a cold apple cider vinegar in hot water is very cleansing for the throat area. Cinnamon and honey is also a great “tea” option. If you live in a really dry place look into investing in a humidifier. If you’re unwell Fishermans Friend are a great option as they also help clear mucous out.
Diet is really important. If you eat well and healthily you will have great energy. Dairy products can create mucous, especially noticeable within a few hours of singing. Caffeine is not great for singers – it can coat your vocal chords.
Sleep – it affects your energy, muscles, focus, stamina, you are at your best when you have great rest. Consistent, adequate sleep.
Exercise, particularly in the morning to get your muscles warmed up. Keep your neck, throat, shoulders, back etc free of tension. Stretching is great too.
Don’t overuse your voice. Be conscious of when you need to rest your voice. This is particularly important for long or multiple worship sets. Make sure your in-ear mix is good so your not internally competing with it.
Speaking voice – most of us talk in the lower third of our range. When you energize your voice (e.g. when talking to a child) you go up in your range a little bit. This is actually a healthier pitch for your vocal chords, so just be aware of it.
Pursue people in your circle who can help you in your vocal health – vocal teachers, worship leaders etc
