Minor Chords
Minor chords sound sad, unhappy or melancholic. A song written entirely in minor chords will accentuate this. A
comic song, though, might deliberately mismatch the theme of the lyric with the harmony – imagine a tragic lyric set
to a series of major chords at a quick tempo, or a happy lyric set entirely in a minor key at a slow tempo.
In most chord progressions, minor chords are combined with majors. This causes a subtle alternation of mood and
tone that can be aesthetically and emotionally stimulating. Some types of music do not have chord sequences in this
sense; in Indian music, for example, there are long scale sequences that are mono-chordal, without chord or key
changes.
The chords of Am, Dm and Em have effective open-string shapes.
