Unfortunately, you are unable to alter the basic timbre of your singing voice to match that of another singer without suffering damage to your voice. That is, if you have a deep-sounding voice and want a high-sounding voice, you can seriously damage your voice by singing or speaking at a high pitch.

Online tutorials provide extensive information about the mechanics of singing, however, the online tutorials are not a substitute for a voice teacher because online tutorials do not provide feedback about your singing nor the progress that you are making in your singing.

As your parents won't permit you to take lessons from a vocal coach, you can strongly consider joining a choir at school or church, which will teach you the basics of singing, the correct posture, breathing technique and other mechanics of singing.

My singing voice is very similar to your singing voice, however, I learned how to sing very well with the voice that I do have because a voice teacher explained to me that I could not alter the basic timbre of my singing voice.

Here are some tips about how to sing better:

1. Know thy voice.

Spend quality alone time with your voice. Take your voice out on dates, so to speak, and really get to know it. You might even try recording your singing voice to hear it more objectively. Find out the answers to these questions:

Is my singing voice big or small? Thin or full?
What kind of vibrato do I have? Fast, slow, medium, heavy, thin, non-existent? Am I able to sing both with and without vibrato? When I sing without vibrato, does it feel different in my body than when I do sing with vibrato?

What is my full vocal range? What range am I most comfortable singing in?
Where is my passaggio (the pitch(es) where the voice changes registers)?
How long can I sing without taking a breath? (i.e. How well do I support my breath?) What do I notice in my body and what do I notice about my tone when I start to run out of breath?

How does it feel in my body when I am singing well and when I am not singing well?
What kinds of food and drink affect my voice negatively/positively?
How long does it take for my voice to "warm up"?

There are no right or wrong answers to these questions—everybody's voice is different. The more informed you are about your own voice, the better you will be able to care for it and improve it.

2. Take care of yourself.

Your body is your instrument and you only get one. So, stay hydrated. Get enough sleep. Don't smoke.

3. Support your breath.

You've probably heard this before by every choral director and voice teacher you've ever had—and there's a reason for that. Proper breath support is imperative if you want your tone to sound the best it can. Unfortunately, it seems like every pedagogue has a different way of explaining breath support, which leads to a lot of confusion. This is an area where a personal voice teacher will come in handy for you. He or she will work one-on-one with you to help you learn or improve your breath support so that your tone is always supported. [Read: "Choral Cliché: Support the Tone."]

4. Keep your jaw loose.

A tense jaw will cause your tone to sound constricted and may even cause you to sing out of tune. So, reduce your jaw movement to only what is necessary and don't chew on your vowels. For example, if you are singing a major scale on "ah," there is little need to move your jaw while ascending from pitch to pitch. Keep your jaw as stationary and as loose as possible, and think of making the shape of the vowel inside your mouth rather than with the muscles in your lips.

Tip 1: Think about breath. Without proper breathing, you aren’t using your voice to its full potential. To find out if you’re breathing correctly for singing, place your hand on your stomach and inhale. Your hand should move out—your stomach should be expanding, not your ribcage and chest. That’s because you need to support your breath with your diaphragm—the muscle underneath the lungs that inflates them. The diaphragm is activated by abdominal muscles, and it’s much stronger than the muscles between your ribs—the muscles you’re using if your chest, not your stomach, expands with your breath.

You’ll need to have strong breath to give your voice adequate support for singing. To do this, you’ll need to use your stomach and lower abdominal muscles to support your breath. Ab crunches and sit-ups can help you build up strength in this area that you can use to project your voice.

Tip 2: Focus on posture. Your breath travels from your lungs straight up through your mouth. If its passage is twisted, kinked, or blocked in any way, it won’t be able to get out efficiently. How you stand has a big effect on how you sound. You should be standing with your legs about shoulder-width apart. Your chest should be lifted to give your lungs plenty of room to expand. Your shoulders should be back and relaxed.

Tip 3: Relax. If there’s tension anywhere from your abdomen to your head, it’ll affect your sound. Your facial muscles, tongue and throat muscles, vocal cords, jaw and shoulders should all be as relaxed as possible. There are plenty of jaw and facial exercises as well as warm-up activities that will help you relax the muscles in your shoulders, face, and vocal cords.

Tip 4: Know where to put your tongue and soft palate. The soft palate should be raised—this will give more space for your voice to resonate. The tip of your tongue should be placed at the back of your teeth. This will keep it from blocking your throat if it’s positioned too far back.

Tip 5: Watch what you eat. There’s nothing better for your voice than water. Period. If you have a performance coming up, avoid dairy and thick drinks for at least three days beforehand. Drink only water the day of the performance.

Tip 6: Don’t strain. Pay attention to your body. If something hurts when you sing, you’re either at the limit of your range or you’re doing something wrong. You should be able to sing at a strong, healthy volume if you’re maintaining proper breath control; if something hurts because you’re singing too loudly, you’re probably not supporting your voice well with your breath—the vocal cords are doing all the work. If you hurt when trying to hit certain high or low notes, however, it may be that you’re trying for a note that’s outside of your range. It’s true that good breath control can expand your range, but the size of your vocal cords determines the pitches you can reach. You may not be able to hit certain notes no matter how well you support your voice. It’s important to choose songs you can sing comfortably. Above all, don’t try to sing if you have a sore throat—you may make it worse.

Tip 7: Warm up before singing. Don’t go straight into a song without a good warm-up first. A good warm-up routine should concentrate on relaxing your body and getting your breath ready, and should start with simple deep breaths. It should progress to light humming from there, and then some scale work once you feel ready. It’s important not to strain too hard during the warm-up process—don’t reach for notes that aren’t comfortable, and don’t sing at the top of your volume.

Tip 8: Get a teacher. A good voice teacher can really help you improve your voice. It’s sometimes hard to determine how you sound when you’re by yourself; even the most dedicated singer can get into bad habits without feedback. A teacher can give you immediate feedback on how you’re doing and address specific problems you may have.

SINGING IS THE OLDEST FORM OF MUSIC AND THE HUMAN VOICE IS THE OLDEST OF INSTRUMENTS. WE LOVE THE MUSIC AND THE SOUNDS FROM IT EVOKES SOMETHING INSIDE US WE HAVE TO RECREATE THESE SOUNDS OURSELVES TO SATISFY AN ELUSIVE FEELING . SO SINGING IT OUT OURSELVES IS OUR OWN PERSONAL SOURCE , HOWEVER SOME PEOPLE JUST DO IT BETTER THAN WE DO AND WE FEEL CRUSHED WHEN OTHERS TELL US WE CANT SING .VOCAL COACHES CAN HELP SOMEWHAT IN SO FAR AS TECHNIQUE AND BREATHING PHRASING AND DICTION BUT NOT TONE OR INATE SOUND QUALITY. SOME PEOPLE ARE JUST BORN GIFTED. BUT .. I WILL TELL YOU A SECRET ABOUT OUR VOICES AND THAT IS OUR OWN EARS LISTEN TO OURSELVES WHILE WE SING IS OK BUT YOU NEED TO RECORD YOURSELF SINGING SEVERAL SONGS AND THEN YOU WILL BE ABLE TO REALLY HEAR YOURSELF OBJECTIVELY YOU MAY OR MAY NOT LIKE WHAT YOU ARE HEARING THEN.
