Описание к видео Steinway concert grand piano hammer voicing with chemical hardeners

Voicing a set of New York Steinway hammers with before and after musical examples. Please note after musical example begins at 10:53 (or toggle between 1:16 and 12:02 for before and after tonal changes). Lacquer mixing ratios: "12:1" was mixed using 2.5 grams of Paraloid B-72 acrylic with 4 oz of acetone resulting in a solution with 2% solids. The "6:1" solution was twice as strong (4% solids) and the "25:1" solution was twice as weak (1% solids).
