Of Changes, &c.
There are two kinds of Changes, viz. Plain Changes, and Cross-Peals; which Terms do denote the Nature of them; for as the first is stiled Plain, so are its Methods easy; and as the second is called Cross, so are its Methods cross and intricate: The First have a general Method, in which all the Notes (except Three) have a direct Hunting-Course, moving gradually under each other, plainly and uniformly: Plain are likewise termed single Changes, because there is but one single Change made in the striking all the Notes round, either at fore or back-stroke. But the Second is various, each Peal differing in its Course from all others; and in Cross-Peals as many Changes may be made as the Notes will permit. In short, as to Plain-Changes, I shall not dilate on them here, it being so plainly understood by every one that lately have rung a Bell in peal; All therefore I shall add is this, That any two Notes that strike next together may make a Change, which may be done either single or double, as you list. The single, by changing Two Notes; and the Double, by changing Four, i. e. Two to make one Change, and two another; which is however called One double Change, and not two Changes; because tis made in striking the Notes of the Bells once round. For the rest, common Observation and Practice bids me stop here, and demands a Clearing those dark Intricacies which attend Cross-Peals.
