'''25/21''', the '''quasi-tempered minor third''', is the interval between [[6/5]] and [[10/7]], and also [[7/5]] and [[5/3]]. It is [[225/224]] sharp of [[32/27]], [[126/125]] flat of [[6/5]], and [[tempering out]] 126/125 makes the 1–6/5–10/7 triad into a [[diminished triad]] where two minor thirds make up a [[tritone]]. It is extremely close to 3 steps of [[12edo]] (300 cents). | |||
25/21 is also an important interval in the [[Bohlen–Pierce scale]], where it represents a "BP whole tone", i.e. the large step in the [[4L 5s (3/1-equivalent)|Lambda scale]]. | |||
