The octave may be divided into two perfect fourths plus one whole tone, to form an '' 'aañjh''. However, in monophonic music, the perfect fourths divided into ''hañbaacin'' may even be stacked on top of each other indefinitely, without regard to octave equivalence, a practice called ''shiilyohookh''. The same hañbaac or melody may be imitated a fourth above or below in this case. | The octave may be divided into two perfect fourths plus one whole tone, to form an '' 'aañjh''.

More recently, the theorist Wañjeyi proposed representing the Sjowaazheñ musical system by dividing the octave into 58 equal parts. One of his rationales was that the perfect fourth in 58edo is 24 steps, a highly composite number. | [[Verse:Tricin/Etsoj Jopah|Etsoj Jopah]] analyzed Sjowaazheñ tetrachords in terms of rational divisions of string lengths.
