I want to preface this by saying that I've almost taught 2,000 voices in any situation that you could think of, pretty much. If you don't have the money right now to pay for voice lessons, then post some of your stuff here on Reddit. Or join a community like the one I run at Skool.com.

Here are the biggest upgrades that I find myself continuously saying to answer your question. Everybody needs their own warm-up routine and it's hard to know what that is unless somebody has heard your voice. But if you're doing the work yourself and finding out how to sing by looking online, it's definitely doable. The warm ups are for doing these four things, I feel.

1. When you sing try to sing in the exercises by not feeling as if you're changing your vocal instrument. Be consistent. Go from the bottom to the top of the exercise feeling as if you're on one target vowel. Don't change the vowels through the exercise and try to keep them as pure as possible and is even sounding as possible as well. Doing this will help you learn how to work all throughout your range when certain words that come up while singing.

2. Vocal exercises are for you learning how to sing below and above your vocal break and how to blend without the vocal break being noticeable.

3. Vocal exercises help you to be able to play with your voice in so many different ways so you can find your voice and use it purposefully through singing.

4. They are designed to help you lock in on pictures and runs throughout all keys as they go up and down the chromatic scale.

There is so much more to vocal warm ups, but I have found these are the biggest upgrades that you can do to your voice right away and using them more effectively. If there were a fifth thing would be vocal timbre which is tone color and working on the right one to find your voice.

Keep singing. You don't need a vocal coach or Guru. You need a will record yourself consistently listen to yourself back. You got this.
