Sound to Music
(understanding Scales)
● Sounds are waves moving
through a medium (air)
● Just like any wave, we can
chart the high and low point of
the wave graphically
● The lower the sound, the
longer the period of the wave
● The higher the sound, the
shorter the period of the wave
over time
● When two waves interact
together, they can either go
against one another
(dissonance) or they can
match at specific points
(consonance)
● Because of the mathmatical
relationship of sound waves to
one another, nature creates
what is called the “Harmonic
Series”
● This series matches the points
where the waves will intersect
one another
● The fundimental pitch is the
lowest (and slowest) wave but
as you increase the speed,
you simply increase the
number of times the wave
moves within the fundimental
pitch.
● Therefore, fundimental pitches
typically contain all the
harmonies in the harmonic
series.
● Pythagoras was the first to
figure out this relationship.
● He played with different size
anvils, bells, strings and
wooden flutes and realized
there was a mathamtical
relationship between them.
● This mathmatical relationship
in nature is why specific notes
interact well with eachother
building the different scales.
● The harmonic series does
not directly give us the
scale, instead it gives us
the ratios of each scale
degree.
● 1 (fundimental),
●
2 9th
harmonic or 8/9
●
3 5th
harmonic or 4/5
●
4 11th
harmonic or ¾
●
5 3rd
harmonic 2/3
●
6 12th
harmonic 5/8
●
7 15th
harmonic 8/15
●
8 2nd
harmonic 1/2
For the Mathmatically Inclined
Intervals
● When two notes are played together, the
difference in the peaks of the two notes creates a
“beat” pattern.
● The more offset they are, the more beats there
are between them.
Common Frequency
● Although note names have been given to pitches
since musicians began writing in all 12 keys, the
decision to standardize the actual beat frequency
of the note A above middle C didn't happen until
1936.
● A 440 is still debated upon but stays the
standard “concert pitch in the UK and the Unied
States.
