In this post we compare the Koshi Terra chime to the Zaphir Twilight.
When you hear these samples you can experience that the Koshis have a much more bell-like tone and the Zaphir chimes a very crystal clear sound
As you can see the Koshi Terra and the Twilight have very similar tunings, some are pitched, some not.
Koshi Terra: G C E F G C E G
Zaphir Twilight: E G B C E G B C (Autumn)
