Creatively demonstrate changes in pitch to Year 5 pupils by playing this short video in which the same piece of music is played on a range of stringed instruments.
A musician tries to mimic the sound of a bear's footsteps. The pitch of a small guitar is too high, but Key Stage 2 pupils can learn how the longer strings of a bass guitar make a lower, more bear-like sound.
The video ends with a question designed to begin a primary classroom discussion on sound and pitch.
