The name //Tenney height// stems from the fact that [[James Tenney]] proposed it. However, it has been proposed that it should be called //Benedetti height//, since the first person to propose it as a consonance measure seems to have been Renaissance scientist and mathematician [[http://www.webcitation.org/6076Lm8r4|Giovanni Battista Benedetti]]. | |||
