What is chest voice?
Chest voice is the register most people speak in. On lower and middle notes your vocal folds are relatively short and thick, and they meet firmly along much of their depth on every vibration. That firm contact makes a sound rich in harmonics, so chest voice sounds full and strong and gets loud easily. The buzz you feel with a hand on your breastbone is sympathetic vibration; the sound itself is shaped in your throat and mouth, not your chest.
Men and women both have chest voice. Most pop, rock, gospel and country singing lives in it or close to it, and a belted high note is a chest-like sound carried higher than usual. Its weak spot is the top. Push chest voice too far up without letting it lighten and you get strain, a shouty tone and eventually a crack. Teachers call this "pulling chest", and it is the most common reason high notes feel hard.
