This translation was made in 2009 for Europiano France by one of its members, Éric Marandas, a piano technician with a doctorate in applied acoustics, who is fluent in both French and English. It is available on their website as the "American Point of View" http://www.europiano-france.fr/le-point-de-vue-americain.html. In 2013, they created their own brochure on the subject, "Conservatoires! quel entretien sur les pianos?" (Conservatories, how should your pianos be maintained?)
