Type of funereal music played on bagpipes?

It all depends on the funeral and who you are playing for, normally slow airs would be played.

Personally, I played Amazing Grace at my grandmothers Funeral...

It all depends, if you are playing at a personla funeral, you can choose, otherwise you may be aske to play specific tunes.

Many hymns are suitable for funerals and most slow airs. Highland Cathedral is also a favorite.
