WEIGHING OFF THE GRAND ACTION - Part 6

WEIGHING OFF THE GRAND ACTION - Part 6

Levers: Hammer weights and travel parameters get amplified or de-emphasized depending on the geometry between keytop and hammer crown. Generally, weight reduction at the key equals loss of hammer rise, and each of the three main levers contributes to this as a give and take. Their relative impact varies, of course, so we benefit by having a well-observed hierarchy in mind as we decide what to try.

Grand Regulation: Key Dip - Part 2

Key dip, the Articulator, specifies a note’s depth of stroke and resulting hammer rise. Along with blow distance, letoff, and other geometry, it fine-tunes aftertouch, the follow-through needed for good and comfortable execution of each note. It also lifts the backcheck to its work and the damper to clear its strings. 

Depth of stroke (dip) as a measurement relates to neighboring keys. But the depth of stroke needed to produce a specific hammer rise and aftertouch is a distance traveled, irrespective of neighbors. So, when we use a dip block or a WNG Dip Tool to set dip, our keys need to be level for our dip to be accurate.
