Our tunable tongue drum has an ingenious tuning system with magnets that let you play six different scales so you can enjoy a variety of soundscapes. 
To switch to one or another scale, simply refer to the diagram inside the Beat Root tongue drum.
Next to the name of each scale is an illustration showing you where you need to place the magnets.
For example, the Zen scale requires two magnets, one on the green placeholder and another on the yellow one.
