Brass Musical Instruments in the Orchestra

In this short video on YouTube, the BBC National Orchestra of Wales introduce us to some brass musical instruments:

Did you see and hear the tuba, the trombones, the trumpets and french horns?

What did you notice about them? Were they different shapes and sizes? How would you describe them?

What sounds did they make? Were they different to each other? In what ways?

How did the musicians play them? Were the different instruments played differently?

If you want you could watch the orchestra again, and have another look and listen?
