The school band
Read the text and decide if the sentences are true or false
The school band
My name is Talgat, and I am very interested in music. If I have free time I always spend it on playing. I play at home and at the music studio. I also have the school band. There are 4 people in my band. I am a leader. I play the guitar. I’ve chosen it because I like how it sounds. Marina is our singer. She always teaches us how to hold microphones correctly. I think she sings perfectly. We have a pianist in our band. She is very talented. Her name is Lena. Lena: “Yes, I can play the piano. The beautiful sound of piano is the reason why I’ve chosen it. You can think that this instrument is easy to play, however it isn’t. It needs a lot of skills. You must learn the notes and feel the rhythm right. My fingers always move quickly, I try to learn a lot of techniques to become a good pianist.” The fourth person of our band is Zarina: “Music takes a very important part of my life. When I was four I chose my instrument, it was the violin. I love how this instrument makes me feel. Every week I have 4 hours to practice playing it. After the lesson we play with our school band. I think we’ll be famous one day because we practice a lot. Music is really important for all of us. It’s important for musicians to find their own musical instrument. It might be guitar, piano, violin, trumpet, drums and etc. Each instrument has its sound and a mix of all these sounds can make magic.

There are two leaders in the band.
Lena thinks that playing the piano is easy.
