By listening, just like if the piano was close to pitch, only 
with a preliminary pulling the string up an approximate 
anticipated amount (determined when you set the A) *WHILE* 
listening. How do you chip a piano up to pitch after 
restringing with an ETD when nothing is a predictable degree low?
