This can happen when you use too much air to sing those low notes (too much air coming out). You are probably coming down from a high note and forget to tone down your breath. For your low notes, sing them a bit more casually and avoid trying too hard.
Make sure you're singing in a suitable range.
Then try talking in a “monotone” (i.e. not adjusting your pitch up and down for emphasis). Then try singing that note you were speaking. With this note which just “comes out naturally” you may well find it easier to maintain a steady pitch.
This is usually due to constriction in your vocal tract, larynx coming up too high, breath pressure too high, tension in your articulators (jaw, tongue), not lifting your soft palate enough and/or not having proper internal and external muscular support.
We can detect a shake in our voice well before it is noticeable to others. So, if you think that your voice sounds shaky, it is unlikely that anyone else will notice it!
Clinical bottom line. Lots of people have shaky voices at one time of another, e.g. when nervous, tired or overstimulated. Other people have shaky voices because of an underlying neurological condition, such as Essential Tremor.
Your voice is shaky. Your voice is crackly. Your voice is raspy or more raspy than usual. You are hoarse; experiencing voice hoarseness.
The answer is yes! Singing is a skill that you can work on and improve with time and practice, and you don't even need a voice teacher to make improvements right away.
Lack of Practice. Sometimes a soft voice can come from as simple a problem as lack of practice. The vocal cords are muscles, just like anything else. Just like a runner needs consistent practice in order to finish a marathon, singers need consistent practice in order to improve their voices.
Listen to your voice and correct the pitch as you sing. If your note is flat, you will need to bring your voice slightly higher. If your note is sharp, you will need to bring your voice slightly lower. Once you have found the correct pitch, try to remember the “sensation” of singing in tune.
The best drinks before singing are warm drinks without caffeine or milk, warm water and herbal teas containing manuka honey, lemon and ginger are ideal. Warm or room-temperature water will hydrate your vocal cords, making them more supple and less liable to injury.
In short, the answer is that there is no “too soft” or “too loud” for vocal health–it's all in how you produce the sound. Here's the longer answer: When it comes to singing “freely” or even healthfully, it isn't really about singing loudly or softly—more about the way you're producing that loud or soft sound.
If you sound like a child, it is most likely that you are not using enough diaphragm support to release your singing voice in a relaxed mode; instead you constrict your throat more, in order to squeeze out your voice.
While we can't guarantee that all bad singers will become “good,” most if not all singers can become better at what they do, if they put in the time and effort necessary. What is this? Bad singers may struggle with pitch, or bad technique, or rhythm, or something else.
Our voice therapists recommend that for every 60 minutes of voice use, you need 10 minutes of voice rest. Overuse can damage the vocal cords, and if you often find you have lost your voice by the end of the day or after an hour of singing, your vocal cords may be experiencing tissue damage.
To be sure, some aspects of singing are influenced by genetics. "There are certainly people who are more natural singers, and the physiological shape of their vocal tracts can give a more or less pleasing natural sound to the voice," Hutchins points out.
A quavering voice is shaky and a little unclear. People's voices are often quavering when they're tired or afraid. If you're about to cry, you might speak in a quavering voice. Quavering voices are a little bit pitiful. When someone's voice quavers, it becomes unsteady, a little like a stutter.
Curious to know what your own voice sounds like? If you don't own a vocal recorder, Beatty recommends taking file folders (a couple of magazines or pieces of paper will do in a pinch) and placing them in front of your ears so they're sticking out from the sides of your head.
When you speak and hear your own voice inside your head, your head bones and tissues tend to enhance the lower-frequency vibrations. This means that your voice usually sounds fuller and deeper to you than it really is.
