“Stairway to Heaven” by Led Zeppelin is recognized for its use of modal interchange, specifically borrowing chords from the parallel minor, and its distinct way of blending rock and folk music elements. This piece is in the key of A minor and the chord progression in Verse 5 is simple but quite effective.

“Whole Lotta Love” by Led Zeppelin is a hard rock song that was released in 1969. The song features a famous guitar riff with a simple, blues-influenced chord progression. That guitar riff is based on the D and E chords and can be heard throughout the main part of the song. The verse consists of the same primary chords as the riff, with slight variations in the E chord during the iconic “You need cooling” vocal part. The overall harmonic structure of the song with its repeating chords D and E gives it a strong I-V dynamic while staying in the D Mixolydian mode. Additionally, the guitar riff borrows elements of other blues progressions, creating a distinguished sound.

The song is in the key of A Major and it makes some interesting use of borrowed chords and modulations. The arrangement of the song is fairly typical rock/pop with a verse-chorus-bridge structure. The bridge utilizes a modulation to the relative minor key, F# minor.

The key of the song “Good Old Fashioned Lover Boy” by Queen is primarily in C Major. The song employs both diatonic chords (chords that naturally occur within the major scale key) and borrowed chords (chords from a parallel mode). There is a bit of modal mixture where the song borrows from an outside key, specifically the minor key, which is often used in pop music to add color and tension. You can see this in the use of some of the chords here like Fm and Eb7. The piece also utilizes secondary dominant chords and diminished chords. In the bridge, there is modulation to different keys, namely to Fm, which is a parallel minor of F, includes Eb7 (secondary dominant) and Ab (borrowed chord), and goes through sequence of V-I pattern (G7-C).
