For IELTS speaking part 1, remember to give short, simple answers. Answer the question with a full sentence and give a reason for your answer. Here are some example questions and answers about musical instruments (from Cambridge IELTS book 6):
1. Which musical instrument do you like listening to most? (Why?)
My favourite musical instrument to listen to is the guitar. I like the fact that there are different types of guitar, like classical, acoustic and electric. I love the variety of sounds a guitar can make.
2. Have you ever learned to play a musical instrument?
I took some guitar lessons when I was younger and still have a guitar at home. I don't play it much nowadays. I wish I had more time to practise.
3. Do you think children should learn to play an instrument at school?
Yes, I think it's a great skill and it's really enjoyable to be able to play a musical instrument. All children should be given this opportunity.
4. How easy would it be to learn to play an instrument without a teacher?
It would probably be more difficult without a teacher. You need someone to show you what to do and correct your mistakes. You need a lot of discipline to teach yourself.
