These are the 4 most common chords in The Beatles’ Beatles compositions. The order of the chords in these tunes is similar to the order of the chords at the end of a chord progression of any kind, so that a chord progression in The Beatles’ songs can have the same order as a chord progression (as it normally does) in a standard guitar chord progression, like the chord progression for the blues or a blues progression in a song on the radio.
Most of these chords are the same as in the blues and rock blues. Many guitar chords in The Beatles’ music could also be found in classic rock (like the chord progression in “Blackbird”) or in modern folk (like the chord progression in “Strawberry Fields Forever”). Some were borrowed straight from other genres (e.g. the chords in “It’s Only Permanence” and “Ticket To Ride”). But most of these are the same as the chord progression at the end of the song.
To get a more useful, yet non-numbers-based picture of the importance of chord changes, try playing through the songs on the following chords (with the appropriate tempo and chord changes included). Notice how many of those changes can be attributed to chord progressions, not simply to chords played by the band, or to chords played by a particular guitarist. You may notice that, for whatever reason, in some of the songs, more of the chords do have more to do with chord progressions than in others.
It’s probably obvious that all of this list, especially the first four, are pretty much the same as the chords in the standard guitar chord progression. But in this song, I’ve got two chords (I and V) that could be considered to have more to do with chord progressions than in any other song, that I use as examples: first, the 1st, 6th, 11th, 6th and 5th (I) and the 7th (V), the ones that were introduced by George Harrison. The other three are the first four in the traditional guitar blues, like the Cm7 chord and the 4th (G).
Let’s take that further. In the song’s first half, I play an extended-upbeats rhythm, so I’ve got an Fm7 chord in the middle, a C7 chord in the top 4, a G7 chord in the middle 5, a Cm7 in the top 3, and an A7 that’s at
