This week, we'll listen for harmonics. We mostly think of harmonics as an element of music but there is a more fundamental physical quality underneath it all. Wave patterns are all around us. We know its how sound and light move and that changes in these wave can influence our perceptions and moods. Checking the frequency with us on this episode of Idyllic Music are Sleepy Koala, Garaz, Dlay, MindsEye, Cutside and DU3normal.
