Sound and Colour
Intone the musical tone and divine/letter sound assigned to a particular Key, Hebrew letter or Sephirah while vividly visualising its corresponding colour, so sound and colour together attune one’s state to the principle that Key embodies.
Sound and colour: Pick a letter / Key / Sephirah and its three attributions — colour, tone, sound. Settle and breathe. Visualise the colour vividly; on the out-breath intone the sound on its pitch, slow and resonant, feeling sound and colour as one vibration. Repeat for several breaths, holding the union. Rest in the attuned state, then let it fade and ground. Sound gently — don’t strain.
What it is
Alongside contemplating the Tarot Keys, Paul Foster Case taught a sound-and-colour practice: each of the 22 Hebrew letters (and so each Major Arcana Key, each path of the Tree of Life) is assigned both a colour and a musical tone — and a divine name or letter-sound — and the practitioner intones that sound while holding its colour vividly in mind.
Case used sound and colour together as, in his words, a “formula of healing” and attunement, distributing a system of letter-tone-colour correspondences through his books and devoting a short study, The Correlation of Sound and Colour, to it.
The idea is that vibration is the common root of both tone and colour (“Through sound the world stands,” he quotes), so chanting the right tone while seeing the right colour resonates the practitioner’s consciousness into harmony with the principle the letter/Key embodies.
Read plainly, it is a paired vocal-toning and colour-visualisation practice — a structured way of using sound and image together to shift and steady one’s state.
The Method
A faithful working sequence drawn from Case’s correspondences:
- Pick the letter / Key / Sephirah you wish to work with, and look up its three attributions: its colour, its musical tone (pitch), and its sound (the Hebrew letter-sound, or, for a Sephirah, the associated divine name).
- Settle and breathe. Sit upright, relax, and take a few slow easy breaths to centre.
- Build the colour. Vividly visualise the assigned colour — filling the field of inner vision, or as a coloured light surrounding or within you.
- Sound the tone. On an out-breath, intone the sound on its assigned pitch, slow and resonant, letting it vibrate in the chest, throat and head. Feel the sound and the colour as one vibration.
- Repeat, holding the union. Continue for several breaths, keeping the colour steady in imagination while the tone is sounded, so attention rests on the fused sound-and-colour.
- Rest in the attunement. Fall silent, keep the colour a moment longer, and notice the felt state the practice has produced — Case treats this attuned state as the point.
- Close and ground. Let the image fade, return to ordinary breathing, and ground. (Sourcing note: a faithful synthesis of Case’s letter-tone-colour correspondence practice; the specific colour and pitch assigned to each Hebrew letter are tabulated in his books and the B.O.T.A. lessons. Note that scholars trace this correspondence set back through Golden Dawn sources — see Section 3.)
Source & Lineage
Case published the system in The Tarot: A Key to the Wisdom of the Ages (1947), the booklet The Correlation of Sound and Colour, and the B.O.T.A. lessons, building on the Hermetic Order of the Golden Dawn‘s scales of colour and its attribution of the Hebrew letters to the paths of the Tree of Life.
Researchers (e.g. Darcy Kuntz) note the letter-tone-colour correspondences themselves were assembled from earlier Golden Dawn material (notebooks associated with Allan Bennett), which Case systematised and taught.
The practice is the sonic-visual complement to his Tarot Key meditation and pairs naturally with the colouring of the Keys. → (Paul Foster Case node, case paul foster); lineage: Golden Dawn, Dion Fortune, Israel Regardie.
Common refinements
Forcing the voice. Intone gently and resonantly; straining the throat or over-blowing the breath causes light-headedness and breaks the focus.
- Letting the colour drift. Keep the colour vivid and steady while sounding the tone — the union of the two is the practice.
- Treating it as a one-off. Like the Key meditation, it deepens with repetition on the same letter/Key.
- Chasing the “perfect” pitch. Approximate the assigned tone in a comfortable register; the steadiness and the pairing matter more than exact frequency.
- Skipping the close. Let the image fade and ground before resuming activity.
