In general, the larger the piano the slower the F-A because of the improved scale and thus less compromise. On many large grands I have actually found F-A to be close to 6bps. Once I get my F I immediately tune the next octave F, (F4). I then tune the Bb in the middle. THis is followed by the F to the C, and C the the D. At this point you have an unquestionable check from the D back to the A, which you no for a fact is correct because it is where you started. If it is way off in either direction then you know you need to re-adjust the F-A again. The Bb to the A also gives you a 3rd test to compair to the F-A. As everyone on this list will tell you there's a million ways to do this, but this seems to work for me. Rob Goodale, RPT
