Music
African music – the feel is very lazy, they are very behind the beat
I thought this was a very interesting point, I have never once thought about what is the item that makes African music so distinct compared to other types of music – the feel of the music being lazy and behind the beat
Sound
Sound is pressure waves traveling through the air
Sound in air is like ripples moving through water
The pitch of a note is determined by its “frequency” – how frequently it vibrates
The higher the frequency, higher the vibration
Every musical note we hear is known as a fundamental pitch (the loudest)
Different instruments have different fundamental pitches, there is an overtone series that makes them sound different
There are physical proportions embedded in the strings of an instrument
Principles of form embedded in the universe
“We shall therefore borrow all our Rules for the Finishing our Proportions, from the Musicians, who are the greatest Masters of this Sort of Numbers, and from those Things wherein Nature shows herself most excellent and complete.”
Leon Battista Alberti
Digital Music Theory
It is physics, it has a mathematical order written to it, and that order is possibly written to the universe
Definition: In Music Theory and Digital Composition, students explore the structure, writing, and recording of music as a design problem, with the intention of creating and releasing a finished piece of original music
Harmonic ratios as room shapes – I did not understand this
Is there some underlying math that rules/runs the world?
The Creation of Vinyl Records
As you sing, the diaphragm would vibrate, that connects to a needle that is connected to a disc made of wax, as you started singing, the vibrations of your voice would cut through the wax, then the process continues until you could stamp the wax disc
1950’s: music was recorded to tape, rather than to wax
Highest frequency humans can hear – 20,000 with perfect hearing, with age it deteriorates
Analogue vs. Digital
Analogue
EX: singing into the microphone, current generated in the microphone, generated by my sound
The electrical current generated is analogous to the sound wave
It is changed its form but has not been created into numbers
I have no idea how this example relates – It makes sense yes but I don’t get how mathematics and physics all tie into this
Electric currents varies with vibrations
Analogue process – converted to electricity
Digital process – converted into numbers, numbers represent possible frequency distributions (any yes or no answer)
