Both versions of the Halo are classified according to their register
(how ‘high’ or ‘low’ their key is):
- Halo Genesis is our lowest-pitched register. It has the most ‘mass or gravity’ to its feel and sound.
- Halo Cirrus is our middle-pitched register. It has a classic range.
- Halo Stratus is our highest-pitched register. It’s known to be ‘sparkly’ and ‘ethereal.’ It has the lightest feel of our ranges.
