With a Love of Music and a Solid Technique,
Anyone with a Speaking Voice Can Learn to Sing
Everyone has a unique voice due to a myriad of biological factors. The first step to developing that voice to its fullest potential is to gain an understanding of the voice and body as an instrument. After all, you can't swap your voice out for a new one at the music store if it is damaged.
Once you understand how the voice and body work, the goal of taking lessons and learning technique is to learn to sing as healthily and efficiently as possible, developing your voice into a fuller, stronger and more stable instrument.
Singing is a wonderful passion. And if you have that passion, you owe it to yourself to pursue it!
Good luck on your journey, wherever singing takes you!
