Why is it an ethical practice for a technician who either does not quite have the skill to pass the RPT Tuning Exam or to pass it only barely, to tune any piano for any purpose with a temperament that is clearly not equal, which has clear distinctions in tonality, so long as ET is what is attempted and so long as that person and the customer believe that the temperament is equal? Why is it an unethical practice to deliberately tune a non ET when that temperament could still "pass" the minimum RPT exam standard as an ET even though clearly, it is not? Who should be informing whom of what the tuning will not be? How much technical information needs to be disclosed before a tuning can be considered to be done ethically? If ET is normal, then is a temperament which is believed to be ET but really is not normal too? If a temperament is not ET, is it abnormal? How much deviation form normal does it take to become abnormal? If a piano is tuned in ET and meets the very highest professional standards as such but the customer still doesn't like it, is that a basis to claim that what the technician has done is right? If a piano is tuned in a non ET and the customer is pleased with the work but was not informed that the temperament is not equal, is that a basis to claim that what the technician has done is wrong?
