It is very easy to get into the habit of singing loudly in order to hit higher notes.
The problem with this approach is that if you don’t have a solid foundation for singing, you will be hurting your voice instead of helping it.
Enter the concept of “sing light and right instead of strong and wrong”. The basic idea behind this principle is that if you can sing the notes correctly with a very light sound, you can sing them louder and still maintain that correct and proper foundation.
I will admit that this is tough at first, especially when you are first starting out singing. There are a few exercises, though, that can help you sing light with more ease.
Lip rolls are one of the best ways to build strength in your voice. Building strength with lip rolls will make singing light much easier.
