190. TWO MULTI-OCTAVES SCALES MADE FROM INTERVALS OF 5THS AND 3RDS (OR 6THS)



The next two scales are made entirely from intervals of 7 semitones , in other words intervals of 5 and intervals of 3 or their complementary intervals of 6ths . They come from successive triad major or minor chords of 2 or 3 frets in the  uniform tuning by 5ths of string instruments. In addition these scales , when reduced to a single octave they give the diatonic scale.


1)   C2-G2-E3-B3-G4-D5-A6-F6-C8     6 OCTAVES

INTERVALS IN SEMITONES

7-9-7-8-7-7-8-7


2) C2-G2-B2-F3-A3-E4-G4-D5    3 OCTAVES


INTERVALS IN SEMITONES

7-4-7-4-7-3-7

Such scales can be used also for tuning of strings so as to give major minor triads with few only frets (2,3 frets)
