In Chennai, India, AJ Block met and recorded with the worldly bansuri flute player Navin Iyer. Listen and enjoy.

This is Didge Project’s first experiment with didge bass–the use of the didgeridoo as the bass instrument in a pop/funk context. The intro sequence consists of entirely didgeridoos. Didge Hop features Tyler Sussman on Didgeridoos, Saxophone and programming and AJ Block on didgeridoos and trombone.

When two didgeridoos drone together, the resulting sound is greater than the individual parts as new overtones and rhythms are created. The sounds of the two didgeridoos on this track form an extremely low pulsing frequency, conducive to meditative (theta) brain wave states. This track is an excerpt from Didge Project's album, Didgeridoo Meditation: An Odyssey Through Consciousness. Do not listen to this recording while driving or operating heavy machinery. This recording is best heard on stereo headphones and should not be listened to on laptop speakers.

The collection of melodic and primordial sounds experienced on the Didgeridoo Meditation CD has enhanced my practice immensely. Energy and sound have become powerful components of my treatment as a psychologist. The level of mind-body attunement assisted with the sounds of breath, didgeridoo, and Tibetan singing bowls provided on this CD have helped both children and adults in my practice to become more relaxed and balanced in their lives. The soothing, ancient harmonies touch the earth's rhythms in ourselves. Helping others to create a sense of well-being and harmony while reducing stress and mental chaos has come full circle from the ancient past to my current practice.

How it works

When your brain processes two different frequencies simultaneously — say, 100 Hz and 95 Hz — the difference between the frequencies is also manifested as sound, in this case a very low pulse at 5 Hz. By simultaneously combining the sounds of two didgeridoos, we can produce and control these low pulses. And the brain itself produces electrical activity in waves, which correspond to different states of mind. So with two didgeridoos, we can produce a sustained pulse at, say, 4-7 Hz, which mimics the brain’s own theta rhythm — a very deep meditative state.

Through a customized set of didgeridoos that we designed specifically for this album, we are able to take the listener on an Odyssey through consciousness, accessing a continuum of brainwave states, from the most active beta state to the deepest delta state.

Brainwave states have been categorized into the following categories:
