While living in Wyoming, I often times was a good 8 hour drive from home and wasn't going to be back in the area any time soon. I had to find a way to tune the piano that was VERY flat and leave it sounding fairly nice, relatively up to pitch and somewhat stable all in one trip. Add to that, the fact that they treat their horses better than their children, and damn sure don't tune their piano on a regular basis. I developed a pitch raise, tuning the piano by ear, no temperment strip, no wedges, just my tuning lever and hitting the keys. Starting with the tuning fork note, I pull each string up roughly to where it belongs. Then I go octaves to the bass, and tune a really rough sounding 12 notes, A0 to A1. I then go in half steps up the scale, using every interval I can to keep on track. My tendency is to pull too sharp. As I go up, I try to improve on the temperment. I don't spend any time being very accurate, just ballpark. This takes about 10 to 15 minutes. I then immediately fine tune. The pitch raise is about 1/3 the cost of a fine tuning. Retune is suggested in 2-4 months. For those pianos that haven't dropped that far but are good condidates for a moderate pitch raise, I tune the center section using my mute strip just like I usually do for a fine tuning. I then tune a few notes either side of the breaks and tune the muted strings in the center section, removing the mute felt as I go. This causes the piano to drop in pitch slightly. I then start all over and retune the center section with the mute felt in and continue to tune the piano as I usually do. The "pre-tuning" of the center section seems to add stability to the end product. Regarding the usage of WD40 (Double You Dee Forte) I always tell people that I wouldn't put that stuff on anything I care about. It's intended purpose is for Water Displacement. Years ago I tried using it under each arm just before I'd go out on a really special kinda date.
