I have been visiting various singing websites lately and have found many of them to have great ideas and ways to help singers.
One thing I have noticed on a couple of the websites is their claim that you don’t need to have face to face lessons to sing well, just watch my videos and you can become the greatest singer. For me this is a one way street.
My comment to this is if you don’t know what you are doing wrong, you can never know what you are doing right.
Feedback is integral to good progress. Feedback is the rocket fuel that propels the acquisition of knowledge and without it, no amount of practice or watching videos is going to get you there.
A singing teacher is not merely there to offer encouragement and assessing levels of concentration, they are also on the lookout for small technical glitches that may have escaped the attention of their student.
You can get the basics from reading material or watching videos, but I would highly recommend you seek out a singing teacher or at least a mentor who can give you appropriate feedback and guide you on your musical journey.
