What are the things which will potentially kill a singing career? These shouldn't be a secret but you would think so when you listen to all the competition TV shows.
The first is no musicianship (or poor musicianship). What CAUSES singers to sing out of tune, off pitch, or even worse: change keys? You may not know what to call it but it sure does sound amateurish or bad and it is sooooooooo irritating to hear. What is that singer NOT hearing and NOT identifying and why don't they know it?
The second is not being able to use the voice without it cracking or breaking. "Air" is not the answer to this but if you think it is, well...you're going to keep cracking.
There are more factors, but a third one is that a singer has no concept of how his or her own voice truly sounds. This can be emotional, mental, physical, or simply a lack of experience and/or training. Get recorded and try to be objective when you hear the playback
The solutions are not so complicated but they do go beneath the superficial and that is also where a true artist goes to improve and learn and thrive and succeed.
