Bb
Way down in Louisiana down to New Orleans
Way back up in the woods among the evergreens
Eb
There stood a log cabin made of earth and wood
Bb
Where lived a country boy named Johnny B. Goode
F
Who never ever learned to read or write so well
Bb
But he could play a guitar just like he's ringin' a bell

Bb
He used to carry his guitar in a gunny sack
And sit beneath the trees by the railroad track
Eb
The engineers would see him sittin' in the shade
Bb
Strummin' to the rhythm that the driver made
F
When people passed him by they would stop and say
Bb
Oh my that little country boy sure can play
End of song Play again?

Which side does the ear lean to?
Our reading: to us the song feels closer to the Bb minor side because the major V chord points straight at Bbm. That is an interpretation, not a rule — the same chords are just as valid seen from Db major, and switching between the two views is exactly where the practice value lies.
Show the degrees above the chords — relative to Db or to Bbm; comparing both readings is a practice of its own.
Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

The key pair is Db major and its relative Bb minor (5 flats). 3 different chords appear 16 times in total; 0 of them sit naturally inside the shared scale. The major V of Bbm brings the harmonic-minor leading tone, giving the minor side a sharper, more dramatic pull; seen from Db, the same F is V/vi, a secondary dominant heading for Bbm. Bb acts as a secondary dominant, briefly pointing at another chord of the key.
There's no textbook cadence here; the chords circle around each other in a loop, so the song feels more like a groove than a series of arrivals.
Empty slices are chords the song doesn't use.
Starting on Bb, the song gives away its key from the very first bar. Bb, Eb, F carry the song: V/ii–II–V/vi relative to Db, V/iv–IV–V relative to Bbm. Bb is the interesting twist: in Db it is a chromatic chord (V/ii), while in Bbm it becomes the dominant (V/iv) that makes the minor side sound so determined. Ending on Bb, the song seals Db as home. The lyric sheet marks 2 section types, so the same chord pattern returns in a clear, predictable order.
This analysis is generated from the song's chords by akorculuk's harmony engine using consistent rules. When you change key, the degrees stay the same; only the chord names change.
