hanges_ is thus: Get the skill of Tuning them with
your _Voice_, by imitating their Notes while _Ringing_. Or if you are
acquainted, either by your self or Friend, with some _Singing-Master_,
or one who has skill in _Singing_, get him to instruct you in the true
Pitch of any _Note_, and aid your distinguishing them; otherwise you may
be puzzled in this, to know which is _Treble_, which _Second_, &c. as in
532641, _&c._

2. To know the places of the _Notes_, is no way better to be apprehended
than thus: The Practitioner ought to form an _Idea_ in his Head of the
place of each _Note_, whether in a direct _Line_, or _Obliquely_; and
representing them by a _Figure_ in his Mind, see (as it were) by the Eye
of the Understanding, each stroke of the _Bell_, as the _Treble_, 1.
_Second_ 2. _Third_ 3. _&c._ so that as the _Ear_ is to direct him, when
to make the Change, so a right Apprehension of the _Motion_ and _Places_
of the _Notes_, ought to be a means to guide his Ear.

3. The Precedency of _Notes_, is of a very obvious Demonstration; thus:
In Ringing _Changes_ the Fore and Back-stroke, successively following
one another, are properly said to _Lye behind_ one another, according to
their places of striking. Or in short, in 12345, the _Note_ that leads
either at Fore or Back-stroke, is said to _Lye before_ the rest, and the
last to be behind, As the 2 is said to lye behind the 1, so it lyeth
before the 3, as the 3 lyeth behind 2, so it lyeth before the 4. And so
of as many as are _Rung_.

4. The manner of making a _Change_, is very common, and needs no
particular, but general Rule; That it is made by moving one _Note_ into
anothers place, Up and Down, as Occasion requires; but usually made by
two _Notes_ standing one next the other, as hereafter may be observed.

_Lastly_, In your Ringing _Changes_, these two things (in which consists
the practick part of this Art) are to be rightly considered, _First_,
Readily to know which two _Bells_ are to make the succeeding _Change_.
And _Secondly_, to consider (if you are concerned in it) what _Bell_ you
are to follow in making it. To understand which the more perfectly, you
must imprint in your Memory, the Method of the _Changes_ prick'd in
_Figures_, and to be expert likewise in setting them down divers ways,
and making any _Figure_ a _Hunt_ at Pleasure; and thus without pausing
or hesitating to consider the Course, you may throughly understand the
Methods; the Four preceding Obse
