What's the difference between 440Hz & 432Hz, and can I choose either for my TerraPan?
These are frequencies to which musical instruments are most commonly tuned. It is standard practice to tune instruments to 440 hertz. Tuning your TerraPan to this frequency will likely be best if you intend to play it with other instruments and/or are expecting the notes to be completely recognizable. Tuning to 432Hz has become popular among people who wish to use their instruments primarily for therapeutic and meditative purposes. Some people believe that the frequency of 432Hz has a balancing affect on the energy within one's body. Evidence of this is cited through cymatics, the study of the effect of sound on matter. There are many comparative YouTube videos that demonstrate the uniform symmetry and definition when matter is stimulated by pitches tuned to 432Hz.
