Music, as you have it, is not known on the Solar Planes, because your instruments are so incomplete and elementary. It will surprise you to know that the greatest instrument in most of the spheres is the Organ; it is not much like yours in appearance. I will describe one to you:- Firstly, you must understand that I can only describe these things to you in "pictures", constructed in the material you understand. The substances of Spirit are eternal, lasting; those of Earth disintegrate in time; not so Spirit.

The Solar Plane organs are larger than yours, and are made with an eye to beauty, and which differ slightly in colour in the various Solar Planes. They are made of a glassy-like material unknown to you. The fingering notes, or keys, corresponding to your black ones, are made of Amethyst or Mother-of-Pearl, and the white ones are made of Moonstone. There are six manuals, and to each of these are twelve "octaves", each of twenty-four myria-tones, - not eight, as in yours. The pedals are made of Chrysoprase and work independently of the hand manuals. The manuals are sloping as yours, but are continued right round to the side of the player. No music is required, and where your music-rest is, - instead, there is a sheet of opaque blue reflector, reaching from the organ to the top of the building. This is really a colour reflector, and on this the musician can see his thoughts of music manifest in colour, FOR COLOUR IS REALLY THE CONCRETE FORM OF MUSIC. I have seen the most beautiful silver colours give forth the most exquisite tones, and I have seen a poor green colour giving little response of pure harmony... The organ is the only sound heard upon this Solar Plane, played by a Mastermind; myria-tones of sound which ascend in Silver Spirals of sound to GOD.

The organ, of course, plays a large part in the Rites, as it does in other planes.

There is one other great difference between the Third Solar Plane and all the others, and that is - there is no great organ [here]. In the Temple... there are pipes; and the players of these pipes are the Little People, known on Earth as fairies AND WHO HAVE THEIR BEGINNINGS IN THIS UNIVERSE... Therefore, there is a constant piping - a tinkling of love and joy, which continually goes up to GOD.

There is no organ [in the temple], but the music proceeds from what would look to you as a collection of pipes, constructed of a substance similar to wood. There are no metallic substances as your metals in the Solar Planes. The music is high-toned, sweet-sounding - as a gentle crooning in the air... (the nearest approach to it being your oboe) which rises... as a perpetual love-praise - having within it a peace, a softness, in harmony with the song in the hearts - to God - of those who dwell on the Fourth Solar Plane.

A great organ is played at the Temple Rites. This instrument is constructed of a substance resembling golden glass, it is crystal-clear glass, flecked inside with the golden dust of the Creative Ray. The tones of this organ are deep and mellow - there are few high notes in this one, the tones are softened trumpet tones, tuned into that stature of music with the Great Creative Ray of GOD...

...And from the Great Organ in the Temple there ascends a praise in a harmony of the Fifth Solar Dimension - a sound of exquisite beauty to the ear, gentle, soft - to That Great GOD of Love.

The Great Colleges labouring in their work for GOD are packed with students, teachers and masters, but no sound, only an occasional sigh of breath, and music from the organ in the Great Temple, which, on account of the atmosphere of the Solar Planes being so pure and clear, issues from the open roof to be heard all over [this] Solar Plane.

There is music from the Great Organ, the tones of which are deep and of an exquisite quality. The organ is... carved from a white substance, the keys of the manuals are made from pieces of pink amethyst...

You can imagine the scene - the faint amethyst light drifting into the domed roof of the Temple, the exquisite perfume, the hushed melody which steals from the great organ, and the wordless chanting from those assembled there. There is no speech, it is not required, only the language of thought.

The organ in the Great Temple is a deep-toned instrument - of a sweet velvety depth of healing quality and harmony; few high notes are used.

[The Temple Rites] are preceded by organ music... the Great Service begins; all around listening to the strains of the Great Organ, and thanking GOD for the privilege of working for HIM.

The Great Temple building is transparent - the walls being made of, what would look like to you, thick blue glass, but it is not glass, it is a substance only known to us... The Great Organ, made of transparent material, is placed in the upper portion of the building. The tones of this instrument are deep, sonorous tones, there are no high notes.

The Great Organ is made of a transparent material similar to thick plate glass in the colour of pale blue; the keys of the manuals are of mother of pearl.

The Organ of the Great Temple is truly an instrument of great magnificence and of a different form from those in the other Solar Plane Temples; the stops are all wind instruments, highly pitched - like the songs of the fairies, the trill of the birds, or the waft of zephyrs. There is no singing, but a volume of airy music of sublime beauty pouring forth, in thought, - symbolised by music in the Temple as a Love-praise to GOD.

The Great Organ is deep in tone.

The Temple Organ is an instrument in keeping with the interior - of great beauty - and constructed of gold-stone, with keys made of Topaz. Its tone is deep in quality and its notes swell in a great diapason of sound which echoes throughout the great city of Sarahnah.
