There is one small change you can make to improve your singing instantly.
I have noticed that I have been reminding my students about this regularly.
Even in warm up exercises, they start the phrase strongly but by the end of the phrase it can be weak, often breathy.
One thing you can improve in your singing overall is to add energy throughout.
Make sure you stay engaged throughout the entire song.
A great singer doesn’t just start a song well. They end them beautifully as well.
A strong ending makes your performance sound polished, professional and full of confidence.
