444 Mr. Farcy's extended Scale 



affords, into the mysteries of this curious subject, I should have 

 been very glad to have seen this done. I will, therefore, now en- 

 - deavour, to give such directions, as may easily enal)le any of your 

 curious Readers, to construct such a Table of Intervals for them- 

 selves. 



The Key Note C, with its artificial Comma under it, or C, is 



o 



placed in a central square of my Table : the squares on its right 

 hand, in the same horizontal range, are occupied by the follow- 

 fv^u ■ G D A' E' B' F'* 

 .ng succession ofVths, VIZ. 353^ ,q^^ ^^2, 208, 566, 312, 



C'» G"* D'4 A"* E"* B''* Fh* C'** G''** 

 58, 416, 162, 520, 266, 12, 370, 116, 474, 



^f,Q and rytj : the same horizontal column containing, in 



F Rb 

 reversed order, or towards the left hand, the Vths, 054 caq 



Eb Ab D^b G'b Cb F% B"bb E'^bb A^b 

 150, 404, 46, 300, 554, 196, 450, 92, 346, 



D'^bb G^bb C'^bb F'^bb B^'b^ , E^bi 



600, 242, 496, 138, 392, ^""^ 34. 



The vertical column of squares passing through C, is in like 

 manner occupied, upwards, by the following succession of Illrds, 



. E G« B* P** r*5 A*3 C*4 E*+ ,G45 

 ^'^•197,394,591, 176, 373, 570, 155, 352, ^"" 549: 



and the same column also contains, downwards, the Illrds, . . j. 



Fb Dbb B b' G'b' E'b* C'b* A'b5 , F'bs. 

 218, 21, 436, 239, 42, 457, 260, ^"^ 63. 



Besides which, two other short ranges of Illrds are added, one 

 at bottom of the Table, not under C, but beginning under D, 



fwith coojj*"'^ extending towards the right hand; and the 



other at top, beginning over Bb f with o^ ) and extending to- 

 wards the left hand. 



Although the C (or Illrds) range of Vths, proceeds no further 

 than 17 towards the left hand, yet the C'*'* (or + 7 Illrds) range, 

 proceeds in like manner 7 Vths fiirther towards the left hand, and 

 others of the ranges above the C range, do the same, in lesser 

 degrees, occasioning the Table to swell out towards the top left- 

 hand corner, as already hinted : And in like manner the C'b+ (or 

 — 7 Illrds) range, extends out to the number of 24 Vths, to- 

 wards the bottom right-hand corner of the Table, and other 

 ranges near, in lesser degrees.
