I will admit that I'm a late bloomer and am very ashamed to admit that I had only heard of the band Revocation last year. I heard some of Dave Davidson's solos and wanted to look into his use of Hungarian minor. For anyone out there who doesn't know what "Hungarian Minor" is, we'll basically be taking a harmonic minor scale and sharpening (or raising) the 4th note a semitone. Let's look at "E" Harmonic minor and "E" Hungarian minor and see how they differ. (See diagrams below)
"E" Harmonic Minor: E F# G A B C D# E
"E" Hungarian Minor: E F# G A# B C D# E
Obvious Hungarian minor characteristics to point out are the 1 & 1/2 tone interval from C to D# (which is also in the harmonic minor scale) but also the Hungarian minor has a 1 & 1/2 tone interval from G to A#. You'll also notice the chromaticism between A#, B and C which has that very quintessential Revocation sound. Let's take a look at the "E" Hungarian minor scale to 2 octaves and get used to the shape. (See diagram below)
Now were going to look at the lick. (See diagram below)
I think of this in groups of 8 semiquavers over 2 beats (well derrr!). If that feels a bit tricky just work through it in 4 note groups and join them together. Obviously you can mix up the pattern and usage when you decide to implement it into your playing and soloing. Enjoy the exotic, evil and slightly chromatic win.
