The '''Benedetti height''' of a positive rational number N/D reduced to lowest terms (no common factor between N and D) is equal to N*D, the product of the numerator and denominator.

The [[logarithm]] base two of the Benedetti height is the [[Tenney height]], or Tenney norm.

The name is based on the fact that the scientist, mathematician and music theorist [http://www.webcitation.org/6076Lm8r4 Giovanni Battista Benedetti] first proposed it as a [[measure]] of [[inharmonicity]]. It may be the first number-theoretic [[height]] function ever defined for any purpose.
