In mathematics, the harmonic mean (sometimes called the subcontrary mean) is one of several kinds of average, and in particular one of the Pythagorean means. Typically, it is appropriate for situations when the average of rates is desired. The harmonic mean can be expressed as the reciprocal of the arithmetic mean of the reciprocals. As a simple example, the harmonic mean of 1, 2, and 4 is 3 1 1 + 1 2 + 1 4 = 1 1 3 ( 1 1 + 1 2 + 1 4 ) = 12 7 .
The harmonic major scale is a diatonic tonality like major, melodic minor, and harmonic minor. Each pair of notes two degrees apart in the scale (e.g. its 2nd note and 4th note) form the interval of a major or minor third, as is also the case for the major, melodic minor, or harmonic minor tonalities,
