Auris instruments are tuned to a five-tone scale: d-e-g-a-h, with d and e repeated. This scale is special because every combination of notes sounds good. It lets anyone play freely, without worrying about playing wrong notes. That’s why it feels fun, easy, and natural—especially for kids and beginners.

The pentatonic scale is used in music all over the world, from ancient folk songs to modern tunes. It’s also the scale that many young children naturally sing in, which makes it great for early music learning through play and listening.

In music therapy, this scale is a big help. Its simple structure supports people with learning difficulties by making it easier to explore sounds.
