Steam Caution

[Michael Jorgensen]

     Every valid voicing method under the sun will destroy hammers if used
improperly, or to excess.  Some, including steam, are just more efficient and
consequently more volatile than others.   The steam voicing Roger Jolly
demonstrated in his class was impressive, to say the least.
