I found this interesting, this morning. It is a discussion about scales and tonality in music from different cultures. To quote from the website
Musician, DJ and producer Nabihah Iqbal celebrates the variety of music systems across the globe.
Drawing on musical traditions from around the world, she takes a closer look at the notes and scales used to make music. She examines how and why our ears hear some music as ‘in tune’ and other music as ‘out of tune.’
There is a more detailed description of the program here
The podcast is available here for the next 29 days (until 27th September) on the BBC Sounds website.
