Sorry to disagree EJ!A conical bore chanter may be, but the Northumbrian Pipes have a cylindrical bore which gives it its sweet tone.
More like a flute with a bag in some ways.
For the technically minded, the chanter is 'stopped' at the end which also gives it a "fairground steam organ" feel as it separates the melody notes.
Only one finger at a time is raised and then replaced resulting in a stoccato effect.
That's why I said it requires a completely different playing technique compared to other pipes.
