If you are a musician, and interested in teaching, then you will never go hungry! There is always a want for tutors - people will always want to learn music and need the guidance of someone else... you!
Ask one hundred random people, and chances are that the large majority will have an interest in singing, or playing some sort of musical instrument. Whether they enjoy singing, or playing, once you ask a little deeper you'll find that a large percentage of this number have at some stage sought the guidance of a tutor.
While the music industry booms, so will the need for tutors. Some people will always aspire to recreate the sounds that they love to hear, others enjoy the relaxation that playing can bring, and some even aim to write their own number one hit. Tutors will always be needed to help get wannabe musicians rocking.
There's another reason why savvy tutors will always find employment and a comfortable income. They know that the process of learning a musical instrument helps a growing child realise a few of life's lessons - practice really does make perfect, and like the date of a recital, a deadline always needs to be planed towards and constant action taken to completing the assignment well, and on time.
Mindful parents are also aware of this, and if they're not, they probably soon will be as the wise tutor advises about the positive benefits of learning the discipline to work at something. The instrument may be slightly irrelevant in the long run, but the lessons learned are completely transferable.
It is possible to earn a good living from doing something as enjoyable as teaching. And you'll find various articles and tips on achieving the best of this career on the net.
