TVhofe who are acquainted with the firft 
principles of harmony, may, by thefe 
tables, find any cencord to a given co- 
jour, and by the numbers which are an- 
nexed to them may alfo find the true con- 
cord and difcord in any given key; that 
is, when any colour 1s taken as the funda- 
inental, from, whence the 3ds, 4ths, sths, 
&c. receive their names. i

thus, a 3d. major to Green is Purple; 
| whereas, a 3d. minor would be Indigo, 
which it is not eafy to underftand, unlefs a 
perfon has a previous notion of the grounds 
of mufic. 
In all keys where the 3d. is minor, the 
notes properly belonging to that key may 
be found thus :—place the notes in their 
proper order, and write the intervals be- 
tween them underneath.

Suppofe Green — D is the fuzdameuntal 
_ colour, or key. note given, and I would 
know what colour is a 4th. to it; when 
the 3d. is minor, D in the Table of Co- 
lours is marked No. 6, and under the 4th. 
in the little Table above, is wrete 5 ;— 
add 5 to 611, which in the Table is G 
= Violet ;—and fo of any other. 
. But when the Key is major, that is, 
when it has a major 3d. the fecond-of the 
firft two Tables muft be ufed ; thus a 3d. 
major to Bb, or Red Orange, is found by 
adding 4 to 2—6 is D==Green. 
A 3d. minor would have been CX 
or Db, which upon the harpficherd, or 
organ, are the fame notes ; this is a dele& 
in the inftrument, and cannot be remedied ; 
but in colours the gradations ought to be 
taken more exact, which may be done by 
the next Table, expreffing the Flats and 
Sharps on every note ;—thus, DXi s blue 
green, more green; and Eb is blue green 
more blue; Cx is yellow green more 
yellow ; Db is yellow green, more green ;
