Invention of the telescope
 September 25, 1608: the lensmaker Hans Lippershey from
Middelburg (the Netherlands) applies for patent for an
instrument “om verre te zien” (to look into the distance).
 October 7, 1608: successful demonstration for the princes of
Orange: Lippershey receives an order for 6 instruments, for 1000
guilders each!.
 within two weeks two other lensmakers (including Lippershey’s
neighbour!) apply for similar patents; as a result, patent is not
granted
 a letter from 1634 mentions an earlier telescope from 1604, based
on an even earlier one from 1590

Galileo Galilei (1564 – 1642)

Born in a musical family: his father Vincenzo Galileo was a
lutenist, composer, music theorist (author of “Dialogus” on
two musical systems), and carried out acoustic experiments

Heard of Lippershey’s invention
and reconstructed it

First discoveries in 1609

Principal publication in 1632 (“Dialogus”
on two world systems), trial in 1633

Rehabilitation in 1980 (!)

Copernicus’ heliocentric model
New accurate measurements by Tycho Brahe
Kepler’s first two laws
Invention of the telescope
Galileo’s discoveries
Kepler’s third law

Newton’s gravitational model of the solar system
This revolution overthrows a system that was in essence in place
for 2500 years. We can hardly imagine the impact on 17th century man.

Foundation of the universe

central to antique cosmology was the idea of
harmony as a foundation of the universe

this universal harmony was present everywhere:
in mathematics, astronomy, music…

therefore, the laws of music, of astronomy and of mathematics
were closely related

in essence, this principle was the foundation of cosmology until
the Galilean revolution
Music of the spheres
9
Pythagoras (569 – 475 BC)

principle that complex
phenomena must reduce to
simple ones when properly
explained

relation between frequencies
and musical intervals

the distances between planets
correspond to musical tones

Johannes Kepler (1571-1630)
Music of the spheres

Plato (427 – 347 BC)

In his Politeia Plato tells
the Myth of Er

First written account of
Harmony of the Spheres

A later version is given
by Cicero in his
Somnium Scipionis
Music of the spheres
19
Later development
 many
different systems were used to assign
tones to planetary distances – no standard model
 different
opinions on whether the Music of the
Spheres could actually be heard
 influence
of Christian doctrine
 macrocosmos
Music of the spheres
– microcosmos correspondence

Boethius (ca. 480 - 526)
Trivium:
 logic
 grammar
 rhetoric
Quadrivium:
 mathematics
 music
 geometry
 astronomy
Music of the spheres
21
Music according to Boethius

musica mundana
harmony of the spheres
 harmony of the elements
 harmony of the seasons


musica humana
harmony of soul and body
 harmony of the parts of the soul
 harmony of the parts of the body


musica in instrumentis constituta
harmony of string instruments
 harmony of wind instruments
 harmony of percussion instruments


The making/performing of music is by far the least important of
these! But this will now begin to gain in importance.

22
Influence of musical advances and
Christian doctrine

from the 11th century onwards, there is an enormous
development in the composition of music




musical notation
advances in music theory (Guido of Arezzo)
early polyphony
Christian doctrine had great influence on the
development of sacred music



sacred music was in the first place a reflection of the perfection of heaven
and of the creator
the 9 spheres of heaven became the homes of 9 different kinds of angels
theories of the music of angels developed

23
The choirs of the angels
 Hildegard
von
Bingen (1098 – 1179):
O vos angeli
Music of the spheres
24
Range more than
2.5 octaves!
Unique in music
history and
not (humanly)
singable

of the planetary
orbits via the five
Platonic solids.

Kepler’s Music of the Spheres


In his Harmonices Mundi Libri V Kepler assigns tones to the
planets according to their orbital velocities
Since these are variable, the planets now have melodies which
sound together in cosmic counterpoint
Music of the spheres
28
Musical example given by Kepler
Earth has melody mi – fa (meaning miseria et fames)
 This is the characteristic interval of the Phrygian church mode
 As an example he quotes a motet by Roland de Lassus, whom he
knew personally: In me transierunt irae tuae


What is the Phrygian mode?
To create a mode, simply start a major scale on a different pitch.

mi

unexpected places

The above tune is in the Dorian church mode
Quiz question: which Beatles song is this?

After Kepler, Galileo & Newton
Universal harmony as underlying principle removed
 End of the Harmony of the Spheres
 Founding principle of astrology removed
 Harmony of the Spheres occasionally returns
as a poetic theme or esoteric idea

Amazing results!

P2 * ( L B )1/2 = 1823 = Mass of Proton

P4 * W2 = 137.0 = Fine Structure Constant

P-5 * ( L / WB )1/3 = 6.67*10-8 = Gravitational Constant

P1/2 * B1/3 / L = 1.496 = Distance to Sun (108 km)

W * P2 * L1/3 * B5 = 2.999*105 ~ Speed of Light (km/s)
Mass of Electron
2.998 measured
(so measurements probably wrong)

Modern musical analogies
WMAP CMB temperature power spectrum
Musical analogies are still possible, but as results, not as the principle

Approach to music and science
 modesty


playing someone else’s composition is bold
understanding the universe is a very ambitious goal
 honesty


play only what you think is right
say only what you think is right
