Is it normal to get a lot louder the higher you when are singing in your chest voice?

Yes, it is normal for the voice to get louder as you sing higher in your chest voice. This is because the vocal folds become thinner and more elastic as you go higher in pitch, which allows them to vibrate more freely and produce a louder sound. Additionally, the higher harmonics of the voice become more prominent as you go higher in pitch, which can also contribute to the increase in volume.

However, it is important to note that the voice should not be forced or strained when singing in the chest voice. If you feel any pain or discomfort, you should stop singing and rest your voice. It is also important to use proper vocal technique to ensure that you are not damaging your vocal folds.
