Create emotional stability and harmonious relationships.

This is one of a series of six 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 fourth note, which resonates to a frequency of 639 Hz.

This frequency works on connecting and harmonising relationships and deals with our perceptions of love. It can help you to change the way in which you interact with the world so that you bring more harmony and balance in your life and can help with issues around self-love and acceptance, loneliness and emotional stability.

This recording contains two tracks, the first you can use in the daytime as it will guide you back to full waking consciousness at the end. The second track will guide you into a deep sleep state at the end, which makes it ideal for using before you go to sleep at night.

When you are instructed to repeat affirmations, connect with positive feelings (e.g. happiness, joy, love), this will help you absorb the suggestions on a deeper level. You don’t have to repeat the affirmations out loud but do make a strong connection with them.

This App includes:
639 Hz Solfeggio Sonic Meditation Audio Track 1 – 36:11 (awake version)
639 Hz Solfeggio Sonic Meditation Audio Track 2 – 42:11 (sleep version)
FA 639 Hz Solfeggio Music Only Audio Track – 11:52

This one is great!

I highly recommend anything by Glenn Harrold. I have been regularly listening to his hypnosis/meditations for several years now. This is one of my favorites and truly helps me re-center and fall asleep at night. Thank you!!

So grateful

Glenn Harrold has really made a difference with all of his hypnosis apps I've used. I rarely sleep without playing one. I am sensitive to tone and sound, and his skillful mix of hypnosis and hertz therapy really helps me calm down at night.

These apps are the best!

I love these apps! I have been stalking the app store for the last few weeks since I heard a new one was coming out. They are so relaxing, and the 528 app is also very healing. I have a two year old daughter, and we always listen during her nap time, and she gets so relaxed she goes right to sleep. I recommend the audiobooks, as well bc you can put them on a playlist and listen all night. Can you tell I think Glenn Harrold apps are amazing?!
