Sound Therapy believes that our bodies contain ‘energy frequencies’ and people sonic frequencies are often wont to reattune these energies once they go off-key. Some proponents also believe it can relieve certain ailments, including anxiety and insomnia. Sound healers (often called “sounders”) say that it works by lowering vital sign , improving circulation, and reducing respiratory rates. Science says, well, not a lot.
Psychoacoustics is that the scientific study of the perception of sound, and it's fuelled researchers' paths to raised understand how it are often used as medicine. to know the basics of sound in healing, we must first understand our brain waves. The nucleus of our thoughts, emotions, and behaviours, is that the communication between neurons. Brain waves are generated by way of electrical pulses working in unison from masses of neurons interacting with each other . Brain waves are divided into five different bandwidths that are thought to make a spectrum of human consciousness. The slowest of the waves are delta waves (.5 to 3 Hz), which are the slowest brain waves and occur mostly during our deepest state of sleep. The fastest of the waves are gamma waves (25 to 100 Hz), which are related to higher states of conscious perception. Alpha waves (8 to 12 Hz) occur when the brain is daydreaming or consciously practicing mindfulness or meditation.
Steel Tongue Drum
A steel tongue drum is often made up of an empty (often 20 lb) propane tank. The tank is flipped over, rock bottom cut/knocked off; and 7 to 10 tongues are cut radially into the bottom of the tank, forming the highest of the instrument. Steel tongue drum also can be made up of new unused tank heads. The tongues are often tuned by the maker by varying the length of the cuts, or by adding weights, often neodymium magnets to the tongues. The steel tongue drum is usually tuned to pentatonic scales but are often tuned to the scale , the scale , or any set of notes the maker chooses. The instrument is played with the fingers or with mallets. The tone is bell-like.
