Tunes with unusual key changes
Bit of a vague question this, but I’ve heard a few tunes played at sessions/gigs which have unexpected key changes in them. A good example of what I mean is gravel walks when it goes into Cmajor in the third (?fourth) bit . I don’t know why this sounds more odd than in other tunes with a minor -> major shift, but it just does.
I’d really like to learn some more tunes with a similar feel but don’t know the names of any. So, what are they called?
