My ten yr old son can sing soprano quite effortlessly and his voice has a vibrato quality too (I think that's what it's called). The problem is that I know next to nothing about singing or voice training, but other people, (his teacher and other parents) have said to me that his voice is lovely. If I want to nurture it at this stage, what would you advise please, vocal training? And if so, what is the price range of individual classes please, we wouldn't have a lot of money, but if it's something he's enthusiastic about we'll try and fund it. Thanks in advance.
