Music Theory 101: From Keys And Scales To Rhyth... May 2026
This guide covers the essential building blocks of music. Think of these as the "alphabet" and "grammar" of the language of sound. 1. The Foundation: Notes and Intervals
A (Semitone) is the smallest distance between two notes (e.g., C to C#). Music Theory 101: From Keys and Scales to Rhyth...
Sharps raise a note by a half step; flats lower it by a half step. 2. Keys and Scales This guide covers the essential building blocks of music
When you play three or more notes at once, you create a chord. The Foundation: Notes and Intervals A (Semitone) is
The set of sharps or flats at the beginning of a staff that tells you which notes to play throughout the piece. 3. Rhythm and Meter Rhythm is how music is organized in time. The Beat: The steady pulse you clap along to. Note Values: Whole Note: 4 beats Half Note: 2 beats Quarter Note: 1 beat Eighth Note: 1/2 beat Time Signatures: The two numbers at the start of a piece.
A (Whole tone) consists of two half steps (e.g., C to D).
"Programs must be written for people to read, and only incidentally for machines to execute."
- Abelson & Sussman, SICP, preface to the first edition
"That language is an instrument of human reason, and not merely a medium for the expression
of thought, is a truth generally admitted."
- George Boole, quoted in Iverson's Turing Award Lecture
"One of the most important and fascinating of all computer languages is Lisp (standing for
"List Processing"), which was invented by John McCarthy around the time Algol was invented."
- Douglas Hofstadter, Godel, Escher, Bach
"Lisp is a programmable programming language."
- John Foderaro, CACM, September 1991
"Lisp isn't a language, it's a building material."
- Alan Kay
"Any sufficiently complicated C or Fortran program contains an ad hoc informally-specified
bug-ridden slow implementation of half of Common Lisp."
- Philip Greenspun (Greenspun's Tenth Rule of Programming)
"Lisp is worth learning for the profound enlightenment experience you will have when you
finally get it; that experience will make you a better programmer for the rest of your days, even if you never
actually use Lisp itself a lot."
- Eric Raymond, "How to Become a Hacker"
"Lisp is a programmer amplifier."
- Martin Rodgers
"Common Lisp, a happy amalgam of the features of previous Lisps."
- Winston & Horn, Lisp
"Lisp doesn't look any deader than usual to me."
- David Thornley
"SQL, Lisp, and Haskell are the only programming languages that I've seen where one spends
more time thinking than typing."
- Philip Greenspun
"Don't worry about what anybody else is going to do. The best way to predict the future is
to invent it."
- Alan Kay
"The greatest single programming language ever designed."
- Alan Kay, on Lisp
"I object to doing things that computers can do."
- Olin Shivers
"Lisp is a language for doing what you've been told is impossible."
- Kent Pitman
"Lisp is the red pill."
- John Fraser
"Within a couple weeks of learning Lisp I found programming in any other language
unbearably constraining."
- Paul Graham
"Programming in Lisp is like playing with the primordial forces of the universe. It feels
like lightning between your fingertips. No other language even feels close."
- Glenn Ehrlich
"A Lisp programmer knows the value of everything, but the cost of nothing."
- Alan Perlis
"Lisp is the most sophisticated programming language I know. It is literally decades ahead
of the competition ... it is not possible (as far as I know) to actually use Lisp seriously before reaching the
point of no return."
- Christian Lynbech, Road to Lisp
"[Lisp] has assisted a number of our most gifted fellow humans in thinking previously
impossible thoughts."
- Edsger Dijkstra, CACM, 15:10
"The limits of my language are the limits of my world."
- Ludwig Wittgenstein, Tractatus Logico-Philosophicus 5.6, 1918
