added a section about alternative notations
Line 124: Line 124:
*adding the ratios of 3, 5 and 9 introduces greater [[error|error]] while giving several more harmonic identities to the 10-EDO intervals.

For alternative notations, see [[Ups_and_Downs_Notation#Summary of EDO notation-"Pentatonic" EDOs|Ups and Downs Notation -"Pentatonic" EDOs]] (pentatonic fifth-based) and [[Ups_and_Downs_Notation#Natural Generators|Ups and Downs Notation - Natural Generators]] (heptatonic 3rd-based).
This is a heptatonic notation generated by 5ths (5th meaning 3/2). Alternative notations include pentatonic fifth-generated and heptatonic 3rd-generated.
 
'''<u>Pentatonic 5th-generated</u>: D * E * G * A * C * D''' (generator = 3/2 = 6\10 = perfect 5thoid)
