Such unconventional chord progressions can also be found in songs by bands such as Massive Attack and Björk, who are also pioneers of the trip-hop genre.

– A# minor over G# (iv/VI)

These examples show the innovative and intricate blending of elements from jazz, funk, and electronica characteristic of the trip-hop genre.

Musical Analysis

C# minor is the tonic or home chord of this progression. The C major that follows is a borrowed chord from the parallel major key (C# major); this is an example of mode mixture or modal interchange, where chords from a parallel key are used to increase the harmonic interest of a piece.

The E over B and E over G# are inversions of the E major chord, which is the dominant (V) in the key of C# minor. The changing bass note—first B, then G#—creates smooth voice leading and adds harmonic interest.
