Improvisation.

This is recorded with a hand-beaten Beat Root Tongue Drum. The scale is the Beat Root's “Major” scale. Beside it lies a Turtle Drum which I used for the two highest notes to add some extra “space” feeling.

Recorded using two Oktava MK 012 MSO2 condenser microphones.
Mixed with Free Software: Linux, Audacity, Kdenlive, Synfig Studio, and a custom program to detect notes and generate a video with waves from the audio.
