If i sounded say… 4 or 5 out of 10 in terms of how good i sounded vocally. At age 16. Do you think with vocal training I could get that up to around 7 or 8 out of 10?
Or do all good vocals come naturally?
As a future music educator I would say the vocal can certainly be trained.
Talent of course is a factor, there are some people who are better naturally suited to the task than others but almost any person can improve their vocal quality through good training and daily practice of proper technique.
It should also be said that each voice has its own unique timbre, and that whether or not a person's timbre is considered pleasing is extremely subjective.
