  •  Spot-on rant, zenbassoon. (13+ / 0-)

    I am teaching my daughter fractions with a monochord.  She knows that when two notes are a "perfect fifth" apart, the ratio of their frequencies is 3/2.   Other intervals have simple fractional equivalents.

    Every harmonic interval has a polymetric equivalent, and we practice playing these on drums.

    I hate the corporatization of our public education system.

      I teach medieval music in a University, and my students are always amazed to see that pedagogy that's several milennia old still works! The discovery of these ratios has long been ascribed to Pythagoras, who lived in the 6th century BC.  However, he didn't believe in writing things down, so it's impossible to prove one way or another.

      If others are interested, the simple ratios are:

      unison = 1:1 (obviously)
      octave = 2:1
      perfect fifth = 3:2 (as WarrenS said)
      perfect fourth = 4:3
      major third= 5:4
      tone/whole step = 9:8

        is to teach music and thus convince the wing nuts that we're really teaching theology, music of the spheres business.
