I'd suggest strip muting the entire piano, pulling unisons in as you go (although that's a bit impractical in the lower part f the treble section). Use your ETD pitch raise program, but don't spend time setting the pins (i.e. move faster).<div> Then do a second pass (assuming the PR was substantial), with your favorite muting method, and get it solid. Might take you even longer, but it is worth the effort. And yes, charge appropriately for your time, and improved results.</div> <div>Patrick Draine <div class="gmail_quote">On Fri, Jan 11, 2013 at 5:04 PM, Duaine Hechler <<a href="mailto:dahechler@att.net" target="_blank">dahechler@att.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I've been tuning, with an ETD, now for about 13 years and I can't seem to get much faster than about 2 hrs. First, 99% of my tunings are pitch raises - one pass - with a very wide range of cents - usually way flat. Hear is the basics I do. - Start from A0 and go up. - Leap frog mutes - (M=mute, TM = tune middle, TL = tune left, TR = tune right, S = String group) (I think this is accurate ? - I had to draw the strings and place and move mutes on paper) M1 - TM1 - M2 | M2 - S2 - M1 | TL1 | TM2 | M1 - S3 - M2 | TR1 | TL2 | TM3 | M2 - S4 - M1 | TR2 | TL3 | TM4 .............. So I think I'm already moving mutes as little as possible. - Pull strings slightly sharp of pitch then back down to pitch (seems better for stability) - Check for stability I know that going sharp and coming back down - takes time. Any pointers to get faster ? On the upper treble, is it better (hearing wise) to pull up to pitch or go down to pitch ?

No way. I will normally spend about one hour to tune a piano. 2 hours if it's a concert tuning. I would try to figure out what the problem is.
