When you sing it is like a painting rather than a photo
A photo captures the light as it is. A skilled photo gives the viewer a glimpse of the atmosphere of the time and place. it is limited though because the camera records the manner of the wave lengths of the various light beams as they enter the lens. A painting acoustically conveys the emotion that moved the artist during the moment. It is an analogue recording of experience.
Your ability to hit the notes allows people to see the picture. You ability to sing with soul helps people to feel the experience.
