New musical sketch/work in progress thing!!
If anyone is so inclined, check out my newest musical sketch for a track called "Within":

https://soundcloud.com/apexparadigm/within-theme-1

It's an instrumental track with 3 guitars, 1 piano and drums.
Guitar is me recorded by me, effects are done with Guitar Rig, from Native Instruments
piano and drums written by me and synthesized with Kontact, also from Native Instruments.

I've been messing with playing in the 5th position in drop tunings,
and thus was the riff born,
then I adapted it for several things and wrote in some drums in a sort-of hastily fashion.
(that's why I call it a sketch)

If anyone wants specifics:
it's in F# harmonic minor at about 93bpm.
with the guitar tuned to Drop C# (Drop D but down half a step: C#, G#, C#, F#, A#, D#)

Harmonic Minor means that you take the minor 7th scale step, in this case E,
and make that sonuvabitch a major 7th instead of a minor 7th by raising it one semitone, or step.
The result is a step and a half gap between the minor Sixth and the major Seventh,
and the major Seventh makes the dominant chord, C#, into a major chord rather than a minor chord, increasing it's functional harmonic resolution potential, and thus "Harmonic" minor.
Harmonic minor has some interesting flavor; it's rather exotic for how similar it is to the natural minor scale, aka. Aeolian mode.

I think it's rather ******* sweet, personally.

Spanish classical music plays on this harmonic structure thoroughly, as do many other things.
Anyway, there you have it.

Feedback is appreciated,
if you listen, I shall be honored to hear what you honestly think.
It may not be your style of music, but I implore you to think about listening.

As always,
thank you for your time.
