An '''EFD''' ('''equal frequency division''') or ''' | An '''EFD''' ('''equal frequency division''') or '''AFD''' ('''arithmetic frequency division''') is a kind of [[Arithmetic tunings|arithmetic]] and [[Harmonotonic tunings|harmonotonic]] tuning in which each period is divided to a number of steps of equal frequency difference. It is a [[period]]ic [[tuning system]]. | ||
