The singer anatomy is complex and contains many parts of the body. I’ll discuss below some of the main parts.
The hard palate – The hard palate is in the top of the mouth and it is forward of the soft palate which is more towards the back of your throat. You can easily feel the hard palate vibrating when you sing with head voice or chest voice. Basically, the more resonance you get from the upper parts of your body will make the hard palate vibrate. The hard palate is part of your skull.
The soft palate – The soft palate is that soft tissue on the top of your mouth back towards the throat and behind your hard palate. I made a lot of progress in singing when I learned to raise the soft palate and open my throat because you’re allowing more air out when you sing. You are not singing with a closed throat and straining yourself when you learn how to raise the soft palate. Also, vibrato develops more naturally when you learn how to use the soft palate correctly.
The nasal cavity – The nasal cavity is just one of the cavities in your body that contributes to your original sound as a singer. It is a space behind the nose and you can play with this area as you sing and decide if you like the sound emanating from the nasal cavity or if you’d rather sing more from your mouth producing a different sound.
Head voice – Your head voice is just voice resonating in your head cavities. I consider the nasal voice part of the head voice. Your head voice again produces different tone than your chest voice and singing from the lower diaphragm. You can now see how you can tap into different cavities within the body to produce different singing sounds. You can also get breath control while singing.
The larynx – the larynx is your Adam’s apple and it holds the vocal chords. Your pitch is manipulated within the larynx and this is why some people call it the voice box. The larynx also protects part of the trachea.
The vocal chords – are little flaps of tissue that vibrate EXTREMELY fast. Just think hummingbird wings, but faster! They are truly a phenomenon in the human body and you can see why it’s so important to sing with proper technique and protect the vocal chords. As you exhale air, they start vibrating and regulate the amount of air being exhaled. This varying regulation produces the different sounds being produced with your voice.
