1. Industrial Ballads including mining, work in mills, sea songs and shanties.
2. Historical songs including Glencoe, marching songs, recruiting ballads
3. Transportation ballads, Australia, USA
4. Love songs, the village, life before the industrial revolution
5. Children’s songs
6. Nonesense songs
