There are lots of singing tips and it could take a life time to give all of them (especially without hearing them)

But essentially when you're going into high notes it is important that you're throat is as relaxed as possible. A lot of people do this by tensing your lower torso for support although I wouldn't suggest going into Diaphragm or pelvic floor muscle work without training or a tutor.

A nice little trick (and you'll notice singers doing it now i've said it) is as you hit the high note to bend your knees.

You see most of the problem with high notes is the thought of "OMG!! This note is far to high and you tense up. But by bending the knees it phycologically confuses the brain as it starts to think down rather than up and you forget just how high the note was.

That's irelevent the fact is it works.

Also try walking, or even running, whilst trying to hit high notes. Again it offers distration. Or put you r hand out and lower it when as you go higher. These are all little tricks.

Also use your cheek bones. It's good to practice smiling when you sing as by lifting your cheek bones your hard and soft pallet (top of your mouth) create more space which allows more room for sound and creates a better vocal quality it also aids the false vocal folds to retract (which is a good thing lol)

Just keep up the work and remember that there are lots of different styles of singing and no one style is correct for everyone :D.

One of the main foundations when learning singing is to learn how to breathe correctly so that you are able to control your breathing when you are singing. Once you master your breath control or breathing technique, you will then be able to hold your notes well as well as improving your tonal quality when you sing. We are all born with correct breathing capabilities. As babies, we yelled and screamed and can be heard from very far away even though our lungs were very small then. Our voices resonated far and wide. Why is that so? It is because we used our lungs and our sound production resonant naturally and effectively.

As we get older, we became lazy as we only use the upper part of our lungs, taking in shallow breaths instead of making optimum use of our lungs. Furthermore we lost the ability to use our natural resonator properly and thus lost our sound projection ability as well as our good voice timbre. As such, we need to unlearn the bad breathing habits with the correct vocal exercises.

Surrounding your lungs is a muscular system called the diaphragm which is attached to the lower, sides, bottom and back of your ribs. When you breathe in, the diaphragm muscle lowers and displace your internal organs. When you breathe out the diaphragm helps to bring in the muscles around the lungs (abdominal muscles) to control how quickly the breath is exhaled just like an accordion squeezing out air in a consistent way.

If you breathe out fast, the diaphragm does nothing and just sits pretty. When you breathe out very slowly, the diaphragm resists the contraction of the abdominal muscles. A good singer will then use this diaphragm muscular system to control the singing breath as it is being exhaled.

Hold your index finger about an inch from your lips and breathe out slowly and try to notice the action of the diaphragm as you exhale. This should be the amount of breath used when you sing. A singer do not need to 'push' or 'force' air through the vocal cords to produce a good strong or loud sound, doing this will create a lot of air pressure against the vocal folds may damage the vocal cords.

Your tummy should move inward or contract when you exhale. It should not be intentionally sucked in because by doing so, it will prevent the diaphragm from working naturally as it should. Instead the abdominal area should remain expanded to the level it was when you inhaled and allowed to gradually decrease naturally at the end of the singing breath.

This is where the excellent singing controlled breathing happens. The singer expands the lungs by inhaling and controls the amount of air expelled when singing by allowing the diaphram muscular support system to expand. So that it feels as though your tummy is slowly blown up like a balloon when the air goes into your lungs. In short, this is what is meant when people say, "Sing from your diaphragm".

The theory is easy to understand, but it requires a lot of vocal exercises and practices to internalize this correct breathing technique until it becomes a sub-conscious breathing habit of a good singer.

It takes obviously some talent, LOTS of patience, diligence, courage, hard work, dedication and LOTS of lessons with a GOOD vocal teacher. Besides, your voice will keep maturing until you are in your mid-30s so you need a lot of TIME as well. Therefore:

THE ONLY SAFE way to learn the correct singing techniques & to improve properly IS to take OFFLINE face-to-face singing lessons with a fully trained vocal teacher! The teacher HAS TO BE in the same room with you, so that he/she can give you proper feedback. However, even the best teachers in the world cannot make wonders, so please be realistic with this. Singing lessons are NOT going to help if one is tone-deaf!

Please do NOT rely on any dodgy web tutorials because that way you can misunderstand things VERY EASILY and develop bad habits, hoarseness, vocal nodules and other nasties IN NO TIME, and even though you would sound good! It is always much wiser to invest a little bit of your money/time to face-to-face lessons rather than wasting the same amount of money (or even more!) to frequent ear-nose-throat specialist visits due to aforementioned problems, so please reconsider this. If you can't afford vocal lessons, then joining a choir is the only SAFE alternative option. And believe me, but even MANY of those who have music as their hobby DO take lessons as well!

Always remember to warm up your voice properly, but please know your limits and don't overdo your voice! Remember the diaphragmatic support, do not strain your throat too much! Also, remember good body posture!

Avoid fizzy drinks (burp danger), dairy products (mucus risk), caffeinated products (coffee & tea included, they dry up your throat) and spicy food (irritation risk)! You can consume these things, but NEVER before singing!

Do NOT shout, yell, scream nor otherwise abuse your voice AT ANY TIME! Also, please respect your vocal range; if your teacher says you are, say, more of an alto (baritone if you are male), then you ARE more of an alto (baritone).

DO NOT try to imitate anyone famous, that will usually give you just bad habits and even damage your throat. You are YOU and your voice is unique, so please learn to cherish that. The world does NOT need copycats.

Do NOT sing, whisper, shout, yell nor scream if having a sore throat/cold/flu, Also, do speak as little as you can if you have flu/cold/sore throat!

Remember to drink at least 2 litres of room-temperature still water every day, not just during singing days!

Smoking is a big no-no, as is inhaling secondhand smoke. Also, avoid staying in dusty and/or moldy environment.
