Key Info
  • Making music using a cattle grid (pt 1/2)
  • Duration: 04:54
  • Jem Stansfield from the BBC One series 'Bang Goes The Theory' explains the link between vinyl records, cattle grids and music: vibrations make sounds. He describes that driving at different speeds over a cattle grid produces sounds of different frequencies, so changing the spacing of the bars in a cattle grid and driving at a constant speed should allow him to make a musical tune. He measures the frequency of some musical notes and calculates the required spacing for the bars. He builds a prototype length of 'cattle grid' and tests it successfully, and uses some calculations to outline the huge task ahead of him in making the required amount of track. First broadcast on BBC One on 'Bang Goes the Theory'.

Ideas for use in class
  • Could be used to illustrate the generation of sound by vibration and to provide a novel context to the applications of sound. Students could repeat some of Jem's calculations involving the speed of the vehicle and the spacing of the rungs. Can be used in conjunction with 13207. This clip accompanies a BBC Teachers' Pack to support Series 3 and 4 of 'Bang Goes The Theory'. The pack can be downloaded from
