On DoHxeaves, or Musical Scales with tivelve Notes. 415 



Key major, in this case, yet it will apj)ear, on counting up 

 from D, that many ot the intervals are false above that note, 

 ill this arranceiiient of the Douztave. 



Mr. Liston denominates that the original ^caJe (p. 28), 

 which the twelve finger-keys give on his Organ, without 

 the use of any pedal, viz.

Wherein, when compared with the last Scale, we have, 

 instead of the minor Second in the first line, the redundant 

 Unison ; instead of the 5th we have the IV, and mste^id of 

 the minor sixth the Redundant Fifth, or Diesis-defective 

 minor Sixth. The second line shows, that three sharps 

 and two flats occur in this original scale. The third shows 

 the intervals betwten the several half notes, as they are 

 vulgarly called, in Chromatic Elements, where 7S + 3»» 

 4 2= VIII, as before; the founh show? the ratios ; and 

 the fiUh, the order of the two tempered douzeave Elements 

 L and 1 mentioned in the note p. 375, and where 7L + 

 5l = Vlll, as before. 



The following Tables, will show the consonances that 

 can be taken true, in the Doiizeaves last mentioned, either 

 Perfect or Tempered, and the Wolves or false notes which 

 TcsuUi for the wfini of additional notes, beyond the num- 

 ber 12.
