I have created a set of 6 Solfeggio Frequency Tubes made from aluminium, 38mm (1 1/2") outside diameter and 3mm (10swg) thick.

The frequencies are 396hz, 417hz, 528hz, 639hz, 741hz, 852hz. They are measured to room temperature around 20c, which is important because we are measuring frequency through air and to gain an optimum result uk room temperature is key. These 6 tubes resonate to the exacting frequencies and their vibration is ably assisted by the high quality material and wall thickness creating a long sustain.

The set includes a wooden stand and mallet at £395 plus postage or collection.
