(Please see Beginning Harmonic Analysis for more about this.) In the melodic minor scale, the sixth and seventh notes of the scale are each raised by one half step when going up the scale, but return to the natural minor when going down the scale. Harmonies in minor keys often use this raised seventh tone in order to make the music feel more strongly centered on the tonic. The harmonic minor scale raises the seventh note of the scale by one half step, whether you are going up or down the scale. There are two other kinds of minor scales that are commonly used, both of which include notes that are not in the key signature. There’s a lot of harmonic variety in the Melodic Minor Scale As with most of our common heptatonic scales, the 5th degree of the Melodic Minor Scale offers a dominant seventh chord, making the perfect cadence. As you probably know minor 7th chords contain the flat seventh. The Melodic Minor Scale offers the harmonization of 5 of the possible 7 different tertian seventh chords (The Major Scale offers 4). They contain only the notes in the minor key signature. The melodic minor contains a raised seventh, hence the scales more biting sound.
To hear some simple examples in both major and minor keys, see Major Keys and Scales.ĭo key signatures make music more complicated than it needs to be? Is there an easier way? Join the discussion at Opening Measures.Īll of the scales above are natural minor scales. Music that is in a minor key is sometimes described as sounding more solemn, sad, mysterious, or ominous than music that is in a major key. So you can't, for example, transpose a piece from C major to D minor (or even to C minor) without changing it a great deal. Music in minor keys has a different sound and emotional feel, and develops differently harmonically. But music that is in D minor will have a different quality, because the notes in the minor scale follow a different pattern and so have different relationships with each other.
(See Beginning Harmonic Analysis for more on this.) So music that is in, for example, C major, will not sound significantly different from music that is in, say, D major. In each major scale, however, the notes are arranged in the same major scale pattern and build the same types of chords that have the same relationships with each other. Each major key uses a different set of notes (its major scale).
