Whether you’re a musician, a music student, or a passionate listener, understanding these examples can deepen your appreciation of songwriting and arrangement.
1. Whitney Houston – “I Will Always Love You”
In the climax of Whitney Houston’s rendition, the song modulates upward by a whole step from the key of A major to B major.

2. The Beatles – “Penny Lane”
George Martin’s arrangement of “Penny Lane” features a subtle modulation from B major to E major, which enriches the song’s bright, whimsical mood.

It exemplifies how modulation can enhance a song’s narrative flow subtly but effectively.
3. Queen – “Bohemian Rhapsody”
The operatic section of “Bohemian Rhapsody” employs a dramatic modulation from B♭ major to D major, heightening the theatricality of the piece.
