The harmonic minor is most notably used in klezmer, Gypsy and classical music. To form a harmonic minor scale you should raise the 7th degree of the scale by a semitone. (see picture)

The Hungarian Gypsy scale may be created from a harmonic minor scale by sharpening the 4th degree of the harmonic minor scale. This introduces an additional large jump (an additional augmented second interval) into the scale, whole step – half-step – augmented second – half-step – half-step – whole step – whole step.

Getting started

Ok To get started we can practice a little with a keyboard. I assume you have a keyboard as it is an essential feature of any (home) studio. To get used to the harmonic qualities of the scale, mess around with all the white keys starting at A and sharpen the seventh key with one semitone. When you have made some riffs and arpeggios it's time to add some chords.

If you are not familiar with chords that you can use when playing a lead melody in harmonic minor scale then please take a look at this website: www.8notes.com. You can find any style of chords there in any key there is with the Piano Chord and Scale Finder.

MIDI

For the sake of speed we will use the midi files I made for this tutorial.

First lets make a good starting point. Start off with the basic chord progression.mid. Now load the file in your sequencer and assign the channel to a virtual instrument, preferably a wind instrument like a clarinet, to set the right mood. Playing along with the chord progression will help you as a guideline for any lead melody you might come up with.

This concludes the first MIDI tutorial, please make suggestions or remarks regarding this article using the comment box below.

Cheating

I made a Kontakt Instrument that only plays in the harmonic minor scale, no mater what key you hit. This is the result of KSP scripting.  Check out the instrument right here
