The '''middle second''', '''28/25''', is the interval between [[5/4]] and [[7/5]], and is intermediate in size between [[10/9]], which it is [[126/125]] sharp of, and [[9/8]], which it is 225/224 flat of. A [[meantone]] where the tone is tuned to be exactly 28/25 has a fifth of size 2 √14/5, or 698.099 cents. | The '''middle second''', '''28/25''', is the interval between [[5/4]] and [[7/5]], and is intermediate in size between [[10/9]], which it is [[126/125]] sharp of, and [[9/8]], which it is 225/224 flat of.
