Perspectives on information, technology and people
04 October 2022 1100-1215
We have discussed music, its form and its representation. This week we will look into music in its components and manifestations.
Let's begin by learning something we didn't know we didn't know.
① info world
We will start each session with one of us standing before the assembled group and introducing us to an "information world" that they are familiar with, but one that may well be new to the rest of us.
This will be voluntary: there will be no one necessarily assigned to do this weekly, though we hope everyone would want to share of themselves by taking advantage of the opportunity.

An extension of the information model you just watched.
John William Coltrane (September 23, 1926 - July 17, 1967) was an American jazz saxophonist and composer. He is among the most influential and acclaimed figures in the history of jazz and 20th-century music.
Born and raised in North Carolina, Coltrane moved to Philadelphia after graduating high school, where he studied music. Working in the bebop and hard bop idioms early in his career, Coltrane helped pioneer the use of modes and was one of the players at the forefront of free jazz. He led at least fifty recording sessions and appeared on many albums by other musicians, including trumpeter Miles Davis and pianist Thelonious Monk. Over the course of his career, Coltrane's music took on an increasingly spiritual dimension, as exemplified on his most acclaimed albums A Love Supreme (1965) and Ascension (1966).
Coltrane remains one of the most influential artists in music history and has received numerous posthumous awards, including a special Pulitzer Prize, and was canonized by the African Orthodox Church.

Why this is important
The most feared song in jazz, explained
John Coltrane, one of jazz's most revered saxophonists, released “Giant Steps” in 1959. The chord progression that makes up the entirety of the song came to be called the “Coltrane changes”; it's known across the musical world as one of the most challenging chord progressions to improvise over.
It's tough for two reasons: The chord progressions are played fast, and they're in three keys. ...
While this song is one of the most complicated in jazz, it's also the perfect tool to learn a few basic music theory principles that drive Western harmony.
