User:CompactStar/HSU notation
Basically just User:CompactStar/RST notation but makes more sense
This is an extension of 3-limit chain-of-fifths notation where prefixes are added to convey higher-limit commatic alterations. But only goes up to 11-limit
81/80 = hyper- (H), 80/81 = hypo- (h)
64/63 = super- (h), 63/64 = sub- (s)
33/32 = ultra-, 32/33 = infra- (i) (same as in Alpharabian tuning)
Similar to ups-and-downs notation, Im must be used instead of i for chord progression roman numeral analysis
