It is easier to play at a fast speed on the english, but what is the feckin point the music is not about speed its about lilt and pulse and rythym, the anglo can be played faster if more row criossing and less bellows changes are used, but a lot of english players should slow down and change or articulate bellows control more often, the anglo because of bellows reversdals is naturally more rhytmic. for morris dancing it is imo really important for english players not to sludge notes. to articulate bellows by either reversing bellows or pulling bellows ryhtmically in the same direction, for northumbrian music finger attack and staccato can be used to stylistically emulate the northunbrian pipes
