BBC Bitesize
Below you will find two links, one to Key Stage One and one to Key Stage Two.
In Key Stage One, there is a range of clips that encourage the children to hear some different types of music, participate and join in with songs and to look at what actually creates sound.
In Key Stage Two, the videos focus more on the elements of music, such as tempo, pitch, melody, texture, etc. These will prompt more detailed discussions of what makes music so important.
In all cases, these videos can be used to encourage to make children compose their own sounds and perform them! Happy exploring!
