"Hesus" by Aegis - special number cover

Date: July 21, 2019
Place: TGCM Main Church in West London, England
I chose this song because it tells us that the One we need in our lives, especially during the times when we feel discouraged, anxious, scared, lonely, depressed, or just about to break down and cry; all we need is Jesus, and accept Him in our hearts. The message of this song is dedicated to those people who needs Jesus the most.
I was suddenly asked to perform a special number for that date. I'm not even sure if I did it right as this was my first time to sing solo in front of many people. I used to sing in choir or groups when I was still a little girl, lost the ability to sing or had problems with my voice upon reaching puberty, and took me a long time to sing again, after many years. Although, I used to sing in Alto before, then people heard me singing in Soprano (I was just singing out of the blue or was asked to try to sing), others were saying I was harmonizing.
To be honest, I really don't get it about what is alto, soprano, or what does it mean when you are harmonizing. I just sing because I wanted to sing.
Please bear with me on this video if I made mistakes, it was my first time. Also, sorry for the video quality, it was not from me or my phone. This was 3 years ago and video was taken on the phone of my mom's friend. Better have it confidential.
