Fifths experiments

Using the two monochords or a duochord and following the style of Lloyd:

  1. Remove both movable frets, tune both strings to unison, typically at lower C (Lloyd reccomends 240 Hz).
  2. Replace the movable fret to the lower monochord, tune it to the fifth above (ca G below middle C). Measure.
    Hint: Use overtones.
  3. Replace the movable fret to the upper monochord, tune it to some random pitch (not too high), tune the lower string to an fifth above. Measure.
  4. Repeat with upper string at the fifth to determine the pythagorean full tone.
  5. Lower the second fifth one octave.
  6. Continue with the cycle of fifths.
