For what it's worth I'd like to add my experience in tuning two pianos that are intended for performance at the same time. I have had this experience a number of times and have worked out a routine which I will offer as a possibility for others. My routine was first to tune the piano Number one, the piano closest to the desired pitch, first, as well as I could tune it. then to take the A from piano one and tune piano 2 to that A. This required moving the two pianos into such a position that I could play both A's at the same time. Instead of using a fork for piano 2 I used the A from Piano 1. the I proceded to tne piano 2 to the same temperament and tuning as I used on piano 1. After that I ckecked the tuning of piano 2 aGAINST PIANO 1 NOTE BY NOTE 1 TO 88. After that I did the unisons. I never had a complaint, and the two pianos seemed to have been relatively related. The key to my approach was to move the two pianos into a position that I could play the same notes on both pianos at the same time. If they are large instruments some shifting may be necessary. the main ob jective was, in my experience, to use piano 1 as the key to piano 2. I hope this experience can be of some use to other technicians. Dan Franklin, RPT
