As I'm first getting the hang of this mod thing, this weeks theme was borrowed an old reddit songaweek created by reddit user 500MillionYears.
This week's theme is the descending chord progression i-VII-VI-V, otherwise known as the Adalusian Cadence, which in itself is a bit of a misnomer as it's usually used as an ostinato rather than a cadence. The Andalusian Cadence comes from flamenco music. In the key of A minor, the chords are
Am - G - F - E7
An historic pop music example is Runaway - Del Shannon - (as an aside, this song has a pretty cool pre-synth keyboard part, played on a Musitron).
As moderator I was hoping to kick this off with a song of my own, but I'm traveling and am not able to write and record for a bit, but maybe some brave soul will post their song.
