Drink plenty of water. You should try to consume at least 64 ounces of water each day in order to keep your body hydrated. Staying hydrated can help to prevent your throat from becoming dry when you sing.
Refrain from yelling frequently or overusing your voice, which can stress and even damage your vocal chords.
Stay away from antihistamines when you are planning to sing. Antihistamines can dry you out too much and cause your throat to become raspy.
Refrain from eating or drinking dairy products before singing, as dairy products increase mucus production. This can interfere with the quality of your voice as well.
Warm up your voice slowly every time before you sing. Sing softly and cover a wide range of notes slowly before you begin any performance.
Use the muscles in your abdomen to support your sound as you sing. This is where your power should come from, not from your throat. Practice good posture when you sing, which helps you to use your muscles efficiently.
Drop your jaw in order to increase the space in your mouth in which your sound can resonate. Project your voice; imagine you're sending your voice out to the rear of the room in which you are singing.
Relax the muscles in your face and neck. Tension in these muscles can adversely affect your tonal quality and your vocal range.
Stay on pitch by imagining you are coming in from on top of a note. This helps to prevent you from singing flat.
Enunciate your words very carefully so your listeners can understand your lyrics.
