Pupils needing extra support 

Could be encouraged to try different materials, grips and pressures; could be prompted to move around to find a clear space on the paper.

Pupils working at greater depth

Should be encouraged to experiment with how they control the materials using the tip, edge or side; could experiment with combining multiple types of lines in response to the music; could select an appropriate colour to use in response to the music and change or combine drawing materials whilst listening.
