Kepler's discoveries revealed that the Music of the Spheres was not simply an ancient, ignorant delusion. It has a basis in reality. He had demonstrated further that the planetary tones were not fixed as previously thought but produced all manner of changing intervals as each planet passed from aphelion to perihelion and back again. Moreover, the heavenly harmony was not for the benefit of the earth but rather the sun since Kepler's observations were heliocentric rather than geocentric. Oddly, this actually reinforced that Ancient Greeks' geocentric layout with the sun as mese. Originally the sun's position was halfway up the celestial ladder and served as the central tone of the heptachord scale but the new view of the universe now put the sun at the centre of it all, which is closer to reality, and so Kepler's scheme actually improved on the ancient concept of the sun as mese.

Kepler made other discoveries between astronomy and music that were very innovative and quite delightful. In traditional astrology, there are 5 celestial Aspects that can take place in 12 different "houses" of the zodiac (now you know what Jesus meant when he stated, "In my Father's mansion there are many houses."). The word "zodiac" means "circle of animals" because the zodiac appears to wrap around the earth like a belt and each sign is represented by an animal (except Libra which is the scales). The 5 Aspects, first proposed by Ptolemy, are the conjunction (two planets in line on the same side of the sun), the opposition (two planets in line on opposite sides of the sun), the sextile (two planets at a 60-degree angle relative to the sun), the square (two planets at 90 degrees relative to the sun), and the trine (two planets at 30 degrees relative to the sun).

While Ptolemy did relate the zodiacal signs to musical tones, Kepler equated these 5 Aspects with their appropriate musical intervals. A conjunction leaves the full zodiacal circle so it represented the interval called the prime (0 half-steps); the opposition divides the circle in half and so represents the octave which always has a ratio of 1/2; the sextile leaves 5/6 of the circle and so corresponds to the minor 3rd; the square leaves 3/4 of the circle and so corresponds to the perfect 4th; the trine leaves 2/3 of the circle and so corresponds to the perfect 5th.
