Mufical notes are written or engraved, on 
or between five fundamental lines, to which 
there are occafionally added one or two 
more in the writing or engraving. Now, in 
order to avoid the obvious inconveniency of 
adding too many of thefe occafional lines, 
Cliff's were invented, by which any particu- 
lar line, or interval, may be made the place 
of any note in the fcale: if, for example, I 
make the place of G the lowed line but 
one, as in the common ^Triple Cliffy then 
the note in the interval above will be A, and 
that in the interval below will be F, and fo 
of the reft. But if I make the upper line 
but one, F, as in the Bafs Cliff ", then the in- 
terval above will be G, and the interval be- 
low will be E. There are other Cliffs to 
anfwer the fame intention j but this is fuffi- 
cient to explain the defign and conveniency 
of this arbitrary method of fixing a parti- 
cular note on any line or interval.
