📝 About this app

This is the second of a series of six sonic meditation recordings by Glenn Harrold and Ali Calderwood, which are based upon the ancient Solfeggio musical scale. Each note in this scale has specific healing properties and this recording uses the second note, which resonates to a frequency of 417 Hz and is associated with the colour orange and the element of water.

This particular frequency works to dissolve emotional patterns and imprints from the past and facilitate positive changes. It will also help to clear other emotional patterns, such as low self-esteem, self-rejection, overindulgence, jealousy and emotional instability, all of which exist within the same vibrational energy. It has been said that the solfeggio tones can even help to release blocks and traumas from past lives.

Glenn Harrold's skilled vocal delivery and guided meditation combined with Ali Calderwood's deep and moving soundscapes tuned to 417 Hz combine to create an amazingly powerful meditation recording that has the potential to clear away blocks on a deep cellular level. Listen now to resolve past traumas and facilitate changes that will leave you feeling lighter and free of old baggage.

There are two audio tracks in this App, the first has a wake up ending for daytime use, and the second has a go to sleep ending which is ideal for bedtime use.

This App includes:
417 Hz Solfeggio Sonic Meditation Audio Track 1 – 37.11 (awake version)
417 Hz Solfeggio Sonic Meditation Audio Track 2 – 42.11 (sleep version)
RE 417 Hz Solfeggio Music Only Audio Track – 10.18

About the Sounds
The music with this series of mediations has been specially crafted and precisely tuned to transmit each of the solfeggio frequencies. By combining these sounds with a guided meditation, you also have the potential to release deep-rooted blockages. These compositions also contain an array of sacred instruments and sounds such as crystal bowls and didgeridoo and sacred chants, which work to further enhance the effects of the Solfeggio tones.
