The Pythagorean Scale a mathematical method that is used to create all the notes of the musical scale from the harmonic series; this scale is called the Pythagorean Scale. The naturally happening harmonics are whole number multiples. To get the other notes of the scale‚ we must use fractions. The harmonic series gives us the ability to create periods of time of perfect 5ths‚ the ratio of 3/2f‚ "f" being the starting frequency. By using these 5ths‚ we can create the pythagorean scale. We can
