Journeys

Journeys

Series you listen to in order. A part counts as completed once you've heard most of it; parts are never locked.

Threshold

0/4 parts

A four-part ritual: a descent from alpha to theta, stillness, expansion and return. We suggest leaving at least a day between parts.

  1. Threshold I · Body Asleep, Mind Awake30 min · Lying down somewhere comfortable; it's fine if you fall asleep.
  2. Threshold II · Deep Stillness30 min · You can write a few sentences in your journal about how the previous part felt.
  3. Threshold III · Expansion35 min · The longest part; choose an uninterrupted half hour.
  4. Threshold IV · Return25 min · It ends awake; move slowly for a few minutes afterwards.

Dream Gate

0/2 parts

A pre-sleep preparation and a morning dream-journal habit. There is no promise of lucid dreams; the aim is to make time for recalling and noting dreams.

  1. Dream Gate · Lucid Preparation20 min · Listen before bed; write your dream in the journal when you wake up.
  2. Pre-Sleep Unwind (no headphones)20 min · Second night: a pre-sleep sound you can also play without headphones; write in the journal again in the morning.

Solfeggio Path

0/9 parts

The nine pure tones of the Solfeggio list, from low to high. The list is a modern spiritual interpretation popularised in the 1990s; there is no scientific evidence and lists vary between sources. For curiosity and listening practice, at a low volume.

  1. Solfeggio 174 Hz · Pure Tone15 min · The lowest tone; somewhere quiet, at a low volume.
  2. Solfeggio 285 Hz · Pure Tone15 min · You can listen lying down or leaning back.

  8. Solfeggio 852 Hz · Pure Tone15 min · You can take a short break and continue.
  9. Solfeggio 963 Hz · Pure Tone15 min · The highest tone; turn it down or stop if it feels tiring.

Chakra Journey

0/7 parts

A seven-stage listening ritual, from root to crown. The tones come from Hans Cousto's cosmic octave set: octave multiples of periods such as the Earth's rotation, lunar phases and orbits. Chakra frequencies are a spiritual practice from various traditions; sets vary between schools and there is no scientific evidence.

  2. Chakra 2 · Sacral · 210.42 Hz10 min · Sacral: the synodic-Moon tone.

Makams

0/5 parts

Five makams of Turkish music in 53-comma tuning: in each, a drone on the tonic and a slow melodic motif. Ottoman sources wrote about the effect of makams on mood; this is a historical account with no clinical basis today.

  1. Makam · Rast12 min · Rast: regarded as one of the most fundamental makams; ascending path, dominant neva.
  2. Makam · Ussak12 min · Ussak: try to hear the comma-flat segah.
  3. Makam · Huseyni12 min · Huseyni: lingers on the dominant huseyni, ornamented with evic.
  4. Makam · Kurdi12 min · Kurdi: the small step (4 commas) above the tonic gives its colour.
  5. Makam · Nihavend12 min · Nihavend: one of the makams closest to the Western minor scale.

Stillness

0/3 parts

Three short listens based on traditional frequency narratives. There is no scientific evidence; clearly labelled, for curiosity.

  1. Schumann 7.83 Hz20 min · During the day, sitting down.
  2. Solfeggio 528 Hz · Pure Tone15 min · In a quiet place, at a low volume.
  3. By the Stream (no headphones)15 min · Closing: with the stream, paying attention to your breath.
