I follow this blog (among many others!) and was struck by this post:

Ben Newmark is a Humanities teaching in a secondary school, and that will give a certain direction how is has arranged his lists. Maybe some things are different for primary class music, or individual piano tuition, but there are many similarities.

I found it well worth a read through, and a bit of ‘ponder-time’, so I asked if I could share it here.
