the making of it move the one up, and the other down, as the _3d_ and _4th_ here has done. The Learner may take notice, that in ringing termes ’tis not usual to say, that a bell makes an up-change, or a down-change; but in short, that it _moves up_ or _down_, which implies the former. When a note makes an up-change, ’tis then said to move _over_ the other note; and when it makes a down-change, to move _under_ it: as in the next preceding example, where the _3d_ note is said to move up over the _4th_, and the _4th_ down under the _3d_, in which manner the terms _over_ and _under_ are given to the two notes that make every change. _Observ. 5._ In the time of ringing changes, two things are by the Practitioners to be well considered. First, to observe and readily to know, which two bells are always to make the next succeeding change: Secondly, if he is concern’d therein, to consider what bell he is to follow in the making of it. Upon a right knowledge of these two things, depends the Practick part of this Art. To make him expert herein, he must before hand perfectly understand, and readily remember the course and method of the changes prickt with figures, wherein he ought to be so well skill’d, as to be able to prick them down divers ways, that is, to make any figure a Hunt at pleasure; which when he can readily and speedily do, without pausing to consider of the course, then ’tis presumed that he understands the methods throughly. But yet he will not be capable to put them in practice, untill he understands the manner of making a change in ringing; neither can he understand that, until he understands the precedency of the notes; nor the precedency, until he understands the places; nor the places, until he knows the notes one from another. Therefore the four preceding observations being first perfectly understood, and also the methods of the changes as before; the Practitioner may then successfully proceed in the ringing of changes; and as a further help therein I will here instruct him. There are three bells concern’d in the making of every single change, except only when ’tis made behind, and then but two: whensoever the note of his bell is to make a change with any other note, his ear must then inform him whether it lies before or behind the other note; if it lies before, then in making the change it must move up behind it, that is, to follow it; and consequently, he must draw down his bell next after that which he makes a change with, which is called an up-change, as I said before. But if the note of his bell lies behind the other, then in making of the change it must move down to strike before it, and consequently he must draw down his bell next after that which the other before followed, this being a down-change. So that the making of an up-change is very easie, because he must always follow that bell which he makes a change with; but a down-change is more difficult, because he cannot so readily
