The use of therapeutic tuning forks began in 1550 in Italy as diagnostic tools for middle or inner ear conditions. Gradually, the technique developed in England, Germany, and France around 1840. Many physicists (Ernest Chladni, Hélène Grimal) demonstrated the vibrations of sound and their power. Numerous studies have been conducted on the influence of sounds on water and the human body. Renowned researchers have deduced the optimal frequency for each organ. The Harmonic Handpan Art produces clear and pure notes. The tone is pleasant, soothing, and relaxing. It can be used in many contexts, including simple performance or therapy. Each Handpan is tuned with a central note and seven additional notes allowing the player to perform as a solo instrumentalist or with a group.
