“I have much pleasure in bearing testimony to the importance of Mr Jackson’s simple but clever invention for rendering the fingers independent of each other, and in preparing them for execution upon any musical instrument, thus greatly facilitating the attainment of execution; and I sincerely hope that his invention will be made public, in order that the world may derive the full benefit of it.”
From Jacques Blumenthal, Pianist.

“I have great pleasure in stating that I consider Mr Edwin W. Jackson’s new system of gymnastics for the fingers a very ingenious invention, and as simple as I believe it to be useful to the student; and if generally adopted would prevent, no doubt, many a headache engendered by the now prevailing system of exercises for the pianoforte and violin.”
From Adolf Pollitzer, Violinist, Royal Italian Opera.
July 24th, 1865.
“Mr Jackson deserves the thanks of every instrumentalist for his clever invention for strengthening the fingers; and those who follow his very ingenious system must find great benefit from it.”
