[[Phi]] taken as a musical ratio (ϕ*f where f=1/1) is about 833.1 cents. This [[metastable]] interval is sometimes called '''acoustic phi''', or the phi neutral sixth. It is wider than a [[12edo]] [[minor sixth]] (800 cents) by about a [[sixth-tone]] (33.3... cents). | [[Phi]] taken as a musical ratio (ϕ*f where f=1/1) is about 833.1 cents.
