Apart from major keys, the other basic tonality used in western music is a minor key. Minor keys are often said to have a sadder or darker sound than major keys. Songs in a minor key use notes taken from a minor scale. There are three types of minor scale – the natural minor scale, the harmonic minor scale and the melodic minor scale.
The A natural minor contains exactly the same notes as the C major scale. The difference is that it starts and finishes on an A note instead of a C note. The A note then becomes the key note. To highlight the difference, the degrees of the scale as they would relate to the A major scale are written under the note names. Notice the flattened 3rd, 6th and 7th.
