Sand
Notes:
My original track for this one was straightforward and perhaps a tad bland, so I made a 2nd attempt at it, trying to create a sense of dynamic build, and including a couple of Phish-style temporary key changes (scroll down to see both tracks). Note that all key changes are “enharmonic,” meaning that the same group of notes remains consistent throughout, but the chord underneath changes. In this case it goes from A dorian to D mixolydian, back to A dorian, to E aeolian, and finally back to A dorian.
If you play the YouTube video, the video will guide you through the key changes with some visual cues.
