Humming exercises allow you to prevent damage to your voice. When you hum, you are stretching the vocal cords and adjusting your voice to different ranges in pitch. Humming is also an effective exercise for practicing deeper-sounding notes. When humming, practice high and low ranges. Humming along to music can train your ear to listen if you are correctly reaching certain notes.
In the lip trill exercise, put your lips together and exhale out of your mouth with your lips vibrating to the released air, creating a "brbrbr" sound. To achieve this, ensure your lips are loose and relaxed. Once you are able to create that sound, practice producing notes with the lip trill, moving up and down the scale. This exercise trains you to control the flow of air while singing, and loosens up and takes pressure off your vocal cords.
Singing the scales is useful for keeping one pitch while singing. The basic major scale is "do, re, mi fa sol la ti". When singing this scale, start from a lower note and work your way to a higher range. Starting from a lower note puts less strain on your vocal cords and allows your vocal cords to stretch a bit before reaching the higher notes.
All your body's muscles should be relaxed before you begin singing. Begin your warm-up exercise by relaxing your entire body in a rag-doll position. To do this, ensure you are standing and then bend at the waist, allowing your head and arms to hang freely. Breathe deeply in and out of your nose for a count of three to four breaths. This will help you to feel calm and focus before you begin to sing.
