Play the top key of a piano. It should be a C. Starting from there, count that key as 1, and count down the white keys to get to 5. That's an F. Do it again, and you'll get a B, an E, an A, a D, a G, and then a C again.
 
Now build chords on top of this. Just triads, all on the white keys. You should end up with the following sequence: C, F, Bdim, Em, Am, Dm, G, C. This is your basic [['''Circle of Fifths]]''' progression.
 
This has turned out to be a rather popular progression. This is probably in part because it uses the strength of the [[Authentic Cadence]], multiple times in a row--especiallyrow—especially if you modify the chords appropriately, you can pretty much produce a chain of overlapping authentic cadences.
 
The basic progression, in Roman numeral notation is as follows:
Line 17 ⟶ 16:
The exact chords can be modified, but the sound is still similar. Note that the first four chords of the minor version are the same as the last four chords of the major version; this overlap is often used by composers to [[Modulation|modulate]] between keys or express ambiguity of tonality for various purposes.
 
The full eight-chord progression (or seven-chord, if you don't count the repeated chord at either end) is pretty prominent when it occurs, but doesn't occur too often. Much more frequent, though, is a half-sized progression consisting of four chords--usuallychords—usually the last four of either progression or the first four of the minor progression (which is the last four of the major one anyway).
 
The partial version, especially when using the last four chords of the major progression or the first four chords of the minor progression, is closely related to the [[Humoresque Progression]], with the only difference being the second chord. The difference is not that great since the two second-chords share two triad notes anyway.
Line 24 ⟶ 23:
* C, F, Bb, Eb, Ab, Db (C#), F# (Gb), B (Cb), E, A, D, G, C
 
The term "circle of fifths" also refers to a circular diagram shown on the right here. This, however, shows the relationships between the different pairs of keys major and minor and how many sharps or flats they have. To put it in layman's terms, there are twelve different notes in each octave, and each one of them has a major scale (along with a minor scale starting on a different note), and they each have some number of sharps or flats, and the circle diagrams them in an easy-to-reference format. This also shows "enharmonics"--keys—keys that can be spelled in two ways, but (generally) sound the same, because notes like F# and Gb are basically the same.
 
'''Note''': The notation "m7b5" (i.e. "minor 7th chord, with flatted fifth") is the ''half-diminished seventh chord''. So, "A#m7b5" is the same as A#<sup>ø7</sup>. The m7b5 notation is just an artifact of the jazz-originated letter-based chord notation system.

{{examples}}
 
==Examples of the full (eight- or seven-chord) progression, or more than half at least:==
* [[George Frederic Handel]], the [[Passacaglia|Passacaille]] from the Suite in G minor, HWV 432: [http://www.youtube.com/watch?v=KV1uXsWdJHk It's a theme and variations based on a theme that is EXACTLY this chord progression.]
* Examples written by [[Antonio Vivaldi]]
Line 39 ⟶ 38:
* [[Franz Schubert]], [http://www.youtube.com/watch?v=pGbh_oAwuOE Impromptu in Eb major Op. 90 #2], starting at 0:23, and again in the recap at 6:07
* [[Gloria Gaynor]], "[[I Will Survive]]", and its covers (which is this progression in A minor, repeated)
* In ''[[Final Fantasy I (Video Game)|Final Fantasy I]]'', the [[Game Over]] theme, "Dead Music".
* [[Leon Lai]], "Summer Love" (the refrain has the first seven chords, in G minor)
* [[Selah]]: "You Are My Hiding Place" (like "I Will Survive", the entire song is built on repeated instances of Bm, Em7, A, D, G, Em, F#; so only the sixth chord is altered, into a very similar chord)
* The [[SNES]] game ''[[Demons Crest|Demon's Crest]]'', several times in the track "[http://www.youtube.com/watch?v=VN5u60S3l6I Palace of Decadence]"
* In the ''[[Rockman Dash]]'' (i.e. ''[[MegamanMega Man Legends]]'') soundtrack, the insert song "Your Wind is Blowing", combines [['''Circle of Fifths]]''' with the [[Humoresque Progression]], by changing the second chord in the minor-key sequence to VI--thusVI—thus producing an instance of the latter within a variation of the former.
* [[Ritsuko Okazaki]], "Serenade", insert song from [[Fruits Basket]], two instances in the verse: A7, G#m7, C#m7, F#m7, B7, E (skips the D#dim chord); followed immediately by A#m7b5, D#7, G#m7, C#m, F#m9, B11, E)
* [[Melocure]], "Agapé" (in the verses: Em7 A7 Dm7 Gm7 Cm7 F7 [[Bb M 7]]; in the bridge: Em7b5, Am7, Dm9, G7, Cm7)
 
==Examples of the half (four-chord) progression:==
* [[King Harvest]], "Dancing in the Moonlight" (Cm7 Fm7 Bb9 Eb)
* [[Talk Talk]], "It's My Life", refrain, right after using the very similar [[Humoresque Progression]]
