1. Start with any key.

2. Look up the relative minor.

3. Go one step to the right and/or one step to the left in the Circle of Fifths. http://en.wikipedia.org/wiki/Circle_of_fifths

There, you have the most popular and pleasant-sounding chord progressions in any key. If you want funkier progressions, go further in the circle.

Edit: The chords sound more jazzy when you go counter-clockwise (it is the circle-of-fourths). Thanks for the correction, @gnaritas.

I couldn't get it to work in Firefox (20 beta).

I couldn't in Chrome on linux either (Version 25.0.1364.152), looks like they've lost their site for the time being, have to check back later.

It now works in FF and Chrome.

The circle of fifths and fourths are the same circle. Clockwise is a fifth, counterclockwise is a fourth.

Thanks. The mirrors were throw up quickly to handle the load and; that link that led you to the analysis area was overlooked.

This is awesome, but I kind of wish that it matched progressions with progressions.

Right now, if I give it I V vi IV, it'll show me "Complicated" by Avril Lavigne. While that song does contain those chords, in that order, they function very differently - because the actual progression is vi IV I V.

If you start with a minor chord and always follow the most likely chords, you end up having the exact chord progression from the song. They were right after all.

First of all - great job! :-)

When I search for any song, I only get the chord progressions of an excerpt, not for the whole song. Question: do you have the chord progressions for the whole song stored?

If yes, why don't you show them? It would be great to use in a fake book...

If no, what did you normally chose? Verse, Chorus? Sometimes the musically most interesting things happen in the Bridge... Why didn't you find the full progression - just for time reasons? I think if you have mostly Chorus progressions, it's quite difficult to deduce general statistical information about "all of popular music", wouldn't you agree?

The "Rel" option uses relative notation for easy transposition. Nice!

Thanks! All analyses on Hooktheory are in done in sections. Analyses load one section at a time. Since songs (well, most songs) repeat the same harmony in each verse / chorus / ... it made sense for use to use the section approach. One the Trends page the section that loads is the one that matched the chord progression you searched (if multiple sections of the same song match, we omit them from the song list). If other sections of a song have been analyzed, there are buttons just below the title so you can see them.
