The number one singing tip that can be given (in my humble opinion) is to look into a quality teacher that has the ability to assess your unique voice.

On your own, you can look into the variety of videos on YouTube that show you the basics, such breathing correctly, placement of the tongue, the raising of the soft palate, etc. That are essential to singing. I am afraid in your case there is not enough information to allow for detailed tips to be given to you. Do you have trouble with reaching certain notes? Sustaining them? Singing on key? What do you wish to accomplish with your voice? What type of music do you wish to sing?

I wish I could be of more help. Good luck 🙂

1. Sing from the "gut" not from the throat. THis means, support your singing with a lot of air. Don't push your vocal cords, especially on high notes. If you are feeling alot of strain then you need to take in more air.

2. Don't "push". If you push your vocal cords you might get a cool sound at first, but eventually (like 20 minutes) your vocal cords will get tired… Eventually you will bust your cords like this, and won'tbe able to sing at all. If your throat feels tired, drink a few sips of water or take a break. When starting, you shoudl never sing for more than an hour at a time.

3. ALWAYS warm up. Your vocal cords are just like any other muscle in your body and work best when warmed up. Warm up by singing scales, arpeggios, vocal excercises, or even just a simple song. Never start singing at the highest or lowest note you can sing, always start in the middle- at a comfortable pitch. This will set you up to hit the high and low notes without straining your vocal cords.

4. Stand up straight. It's the only way you'll get a good breath.

5. When breathing thing "out" not "up". When you breathe you usually only fill up about a third of your lung capacity. By breathing "out" and then "up" you can use up ur whole lung.

6. Always start with easier songs then work to harder ones.

7. To get louder, let out more air, don't scream or shriek.

8. Remember that practice makes perfect! You don't have to sing for two hours a day, but if you sing for even 15 minutes every day, you will improve greatly =]

Physical Tips
The muscles used for sit-ups or leg lifts are the same used to support (or press) air through the cords to bring forth a singer's sound. Some of these exercises, on a regular basis, add power to your overall tone.
Your jaw should drop — as it does when you yawn — whenever holding a note in your upper range.
If you have to cough or clear your throat, do so gently. These actions are like sandpaper to your vocal cords.
Eat and sleep properly — and ideally — exercise daily. All of these things will enable your body to achieve a state of relaxation and vocal-cord readiness and will benefit your singing more than you'd think.
Maintain a high level of water in your body. The old adage eight glasses a day… Helps keep your vocal cords lubricated and conditioned.

Breathing Tips
The significance of the diaphragm as a muscle of breath support is over-emphasized by most music singing schools and teachers. The diaphragm has two jobs: it furnishes the power for inhalation and then controls tone support.
When you take a breath for singing — to open the throat — add a yawning feeling as you're about to produce the tone (the beginning of a yawn, to be exact).
Be sure the shoulders do not raise when taking a breath.
If you can hear your inhalation, you're taking in too much air or your stomach is tense. Be sure your stomach is relaxed before, and as, you inhale.
Always inhale gently when singing. Heavy gasping of air will tighten your throat.

Essential Tips
Posture is the foundation. Be sure your posture is erect when singing — not a military stance, but comfortably upright. This positions you for maximum support.
Always imagine the sound that you want to make and then sing it — using all resources available — your entire physical being, emotions, psyche and spirit.
A tight jaw is bad for good singing. Do whatever is necessary to relieve your jaw, neck and shoulders of tension before you sing.
Don't smoke. Smoking puts at risk the entire mechanism you're going to stake your claim to a vocal career upon.
Don't try to imitate another singer's voice. Discover your own, unique, vocal identity.

Singing Tip 1. Practice breathing exercises for singing. A lot of people can actually sing real well but do not realize that they are overtaxing themselves and their voices because they are not breathing the right way for singing. Doing breathing exercises for singing will help you sing better.

Singing Tip 2. To improve on pitch problems, practice scales. Scales is the exercise where you start from a low pitch and slowly go up with each repeat of the exercise.

Singing Tip 3. Posture is actually important when you sing. Having the right posture for singing will help you breathe easier and will help you sing better.

Singing Tip 4. Sing within your vocal range. Do not force yourself to sing outside of your range simply because you think it can be done or it will make you more popular. Straining your voice on songs that are not in your range can actually damage your vocal chords.

Singing Tip 5. Your range may change over time and with practice and patience, you might be able to hit notes you never hit before. You will need to constantly condition your voice, train and practice to be able to achieve this in time.

Singing Tip 6. Never sacrifice tone for range. If you think that the higher the pitch you reach despite the rather irritating tone you produce for it means you are a better singer, you are wrong. Some people may give you singing tips that tell you to try and sing beyond your range to enable you to hit those high notes. This is wrong. A lot of good singers cannot hit a lot of very high notes but are still very successful because of the quality and tone of their voice.

Singing Tip 7. Warming up before you sing is essential. To properly warm up, don’t start at the lowest pitch you can manage. Instead, start in the middle, go down, go up then back to mid again.

Singing Tip 8. Pronouncing your words right when you sing also has a bearing on how well you will sound. You should try to do vowel exercises and pronunciation exercises along with your other warm up exercises before you sing.

Singing Tip 9. Constant practice is the key. If you find your progress somewhat slow, maybe you are not practicing regularly. If you want to improve your singing faster, devoting half an hour each day to training can actually do wonders.

Singing Tip 10. Never give up. If you find that all of the singing tips you get and the many different training exercises you find on singing seem to be too much for you, don’t give up – just tone things down. Do what you think you can do every day and just do that. Little by little you will soon see improvements.
