(4.12)  Other Exotic Scales

While we looked at the Japanese and Spanish scales in some detail earlier, there are also many other exotic scales originating from music of Eastern Europe, Asia and the Middle East.

Although they don't often appear directly in western music, they are powerful ingredients for adding melodic and harmonic spice to 'plain vanilla' western music.

Some of the most common examples you are likely to find are shown below.   When played, they can evoke strong echoes of the traditional or contemporary music of their respective cultures.

Even though these scales sound very different from the Major scale, they still share the property of having seven notes.  The names of their degrees are therefore chosen carefully, so each of the seven note letters (A to G) is used once.

In other words, the fourth note of the C Hungarian Minor scale is called F# - not G♭ - because there is already a G as the next note up.  This makes it easier to write melodies in these scales on staff lines, but there are still likely to be many accidentals.

It would seem possible to make up your own 'irregular' key signatures to suit any seven-note scale (including the Harmonic Minor, Melodic Minor, and Spanish).  For example, here is one to suit C Hungarian Minor.

You need to exercise extreme caution with these, however, as classical music theory insists that only the Major key signatures are valid, and your 'irregular' key signatures would not be widely understood by other players.
