Hi folks! Hope this is interesting/of use!
I've used the well-loved tune Brighton Camp (The Girl I Left Behind Me) to show how I approach playing both melody and accompaniments in various ways on the 20b C/G anglo.
The video starts with me playing and then it goes on to a discussion/demo.
Brighton Camp is used for a dance we do with my local side Bow Brook Border in Worcestershire, so when I’m not dancing I’ve been jamming along with melodeons/accordion/fiddle and a lot of their tunes are in G major. Some seem to lie easily on the anglo and immediately can be accompanied whilst playing melody. Others require a bit more thought and experimentation. Interesting though!
