This is a static set of aluminium tubes, made from premium quality materials, made by Emrys Skye at Dragon Frequency based in the Norfolk area of the UK. They are designed to hang from a beam, ceiling, stand and elsewhere. They are used in sound journey work where the practitioner desires the use of high quality frequencies. This complete kit weighs approximately 4kg and comes with a wool headed mallet and a sturdy canvas carry bag with 5 individual sleeves to protect the tubes. Details: These are 1 1/2" (38.2mm) diameter aluminium tube with a wall thickness of 3.2mm. They are tuned to create a resultant tone when all five tubes are played as a collective. The lowest tone is known as the Gateway dragon, followed by Om, Alpha, Omega and the Pulse dragon of Infinity. These are used to help connect from the 9th D and above and used in Dragon Frequency work. Your investment: £249 including carry bag, woolen mallet and UK shipping.
