Seven fifths on the 'natural' keys F-C-G-D-A-E-B-F# are smaller than pure by 1/5 syntonic comma, three fifths are pure (f#-c#, c#-g# and f-bb), the fifth ab-eb is tempered by 1/5 syntonic comma and the fifth eb-a# is enlarged by 1/10 of a Pythagorean comma.
This temperament has been used in the organ at Greyfriars, Oxford, St Paul's, Deptford and St Giles-in-the-Fields.
