savors

Practicing on a cold chromatic causes the warm condensation from your breath to collect on the reeds and wind-savors, causing the annoying buzz we hate so much. The answer is to warm it up. Some players stick it in their shirt pocket near their body, put it under their arm or even on a little heated pillow throne (very regal). If you use a laptop, just rest it on your laptop for a bit... this works great.
