Don, The Doric is spoken in the North EAST of Scotland in Aberdeenshire. It's almost like its own language in a way. As you head nearer to Inverness-shire the Aberdeen ' twang' disappears and you'll find Inverness folk ( Invernessians ) have their own accent. Much of it has gone sadly with so many incomers from Eastern Europe.
As you leave Inverness and head westwards then the accent changes again. The people of Skye, Lochalsh and all along the west coast have a lovely soft spoken lilt to their voice, almost musical. Up in the far north of Scotland The accent changes again, in Shetland, it's almost like another country, even the dances are faster there than on the mainland. For such a small country, Scotland has a heck of a lot of regional variations, not just in their accents but in cooking, lifestyle and dress wear.
I'm not sure if it's on youtube, but this funny monologue IS on spotify by the late Andy Stewart. Andy pokes gentle fun at the various accents of Scotland.
