Specially metered drumming to reduce heart rate and blood pressure. The drum beat is in three, which corresponds to a normal heart beat. Track 1: Native American drum that gradually decreases from 80 to 50 beats per minute. Good for shamanic work to help you into a hypnotic state with the slow steady beat of the drum. Your body rhythms try to synchronize with the drum. Track 2: Native American drum with Andean clay flute, alto recorder, flute, cello, and recorded wind sounds decreasing from 80 to 50 beats per minute.
