This requires a synthesizer capable of altering its home frequency tuning away from its native 440, to settings both of 432 and 528, an amp and a speaker. Place the speaker next to a glass filled with water and play the tone of 528, or even 440, loud enough so that the speaker causes the water to resonate. Notice the uneven and rather mushy wave patterns. Then tune to 432 and watch the water surface dance and perform in nicely arranged patterns. If you dont get the results, chances are youre doing it wrong.
