Sample:
Dear Mr. Peterson,
I am writing to apply for a membership in your musical band. My music teacher, Prof. Huntington, strongly recommended that I attend such a renowned organization, telling me that it would benefit me in many years to come.
I have been loving music ever since I was in elementary school. I learned piano at eight and flute at twelve. I hope I can grow up into a good saxophone player in your team-with so many music lovers around me, I will surely become more creative and enthusiastic.
If my application could be taken into favorable consideration, I would be most grateful. I am looking forward to your early reply.
Best regards.
Yours sincerely,
Li Ming
