and his Essay for explaining its Principles and Use. 375 



In like manner as the Minor and Major Intervals of the 

 Scale are at two unequal distances or intervals apart, as 

 mentioned above, the Sharpen'd Notes of Mr. L.'s Scale 

 are also at two different distances from their naturals*, in 

 different parts of the Scale, and so have flats two different 

 effects, on different notes, respectively : thus, 



1st. The Interval between

 minor; and 2nd, between

 2g + 2S, or 472 + f + 4m, the Semitone niedius, both 

 of which kind of sharps, being on major Intervals, are 

 called Redundant Intervals by Mr. L., and the word major 

 is omitted, as Redundant Second, Redundant Fourth, &c. 

 3rd. The Interval between

 lor 3rd ^ b3, & 6th & b6 / ' '^ ^ "^^^ the Semitone 

 medius, both of which kind of f^ats, bein^ on minor Inter- 

 vals, are called Diminished Intervals, and the word minor 

 is omiited by Mr. L. in naming such, as Diminished 

 Second, Diminished Fourth, &c. 



T must reserve a further account of this interesting volume 

 for another communication, only mentioning, that Messrs . 

 Flights have verv nearly finished a new Organ on Mr. 

 Lisiou's construction, with bF and other additional Notes, 

 so as considerably to extend the Scale, and perfect more 

 Keys, than on the Organ made in Scotland, which Mr. 

 Liston exhibited last year, and which is still open daily for 

 the inspection and hearing of the lovers of Harmony, who 

 will not neglect, I hope, to treat themselves with examina- 



• In all re;jiilarly Trnipcrcd Scales, there is but one value to Sharps, and 

 tlie same is alio the value of the flats, tiiroughoiit the fcnle, a:id it is called 

 Minor Linima (1); between tliese and the next adjoining' notes are Majof 

 l.immas (L) ; and every regular Doujcave is corapoted of 7T + 51 in each 

 octave, ill an invaiiahle order. 



t *B, ivc, or //Vll and VIII, «1'' asd '/«F or IV and *IV, &c. do not 

 readily appear to be agreeable to lyir. L.'s principle of naming the Interval?, 

 on -which account I have stateil these intervals as above C, althoujjh UbD, 

 bijC;. WiC, btiK and bbA are not in his Scale. It is ob->ervable. that in double 

 Sharps and double Flats, one of such is t — H and the other '1' — 1 1, so that 

 the value of each bli is the same, viz. the Redundant L.ininia el AI.-. i.iston, 

 = T + t — 2H, = 2f + 3g + 3X, or SOS + 2f + Tin.
