Honesty and Reality
Your singing voice will be very close to your speaking voice. Your voice is as unique to you as your fingerprints are.
The emotion in your singing must be real and true. No one else has the same exact experiences, relatives, friends, and influences as you do. The meanings that you give things are unique to you. All of these things will affect how you feel, interpret, and sing a song.
You might consider writing lyrics and/or songs because in doing so, you will discover your uniqueness. When you write, be an artist, NOT a critic. Give yourself the freedom to express without judgement. I have written over 2200 songs and I write most days, exploring new possibilities.
The subject is vast.
I still study and learn new things.
Don’t be afraid to emulate a singer, to learn style, phrasing, dynamics, and musicianship. That process does not end there. It is the first step. After emulating (it is not the same as “copying”) then experiment with the song. See what might be changed, altered or improved. It could be the rhythm, the melody, the dynamics, the phrasing, the words, or anything that could make it more personal to you.
I practiced and recorded myself for about 3 hours a day for a year. There was a lot of self discovery in that journey. After a year, I had a recording that did not embarrass me for others to hear. I took it to a show producer in Las Vegas. She told me she wanted me in her show but that I still would have to audition in front of the cast. The audition went quite well. After a year of intense practice, when I finished my audition, the applause and accolades from the other cast members were also intense.
I found one unique aspect to my voice in one specific style but also could (can) do others. It comes down to just being yourself and preparing and then giving your all.
