for those on the fence about hearing protection..

[David Ilvedson]

The outside first then center muting technique probably isn't much use for strictly aural tuners unless they want to set both outside strings aurally...
But for ETD users who tune unisons as they go, it is well worth at least investigating.   I find it is kind of hassle on uprights as the strings are closer together and you have to use rubber mutes.   They also tend to pop out with heavy key action unless you are holding on to the mute.   Maybe a Papps mute would stay in better under a heavy blow?   On grands it does take a little more mute moving but I'm finding worth and it is automatic right.   Now haven't really made a commitment to right string or left string first.   I seem to be doing right string at the moment as that is what Jim Coleman wrote...probably makes no difference...I do know if I'm changing the pitch 3 cents or more I might as well go through it twice or go back over the unison a second time before moving on...although, I think any pitch correction to tension change probably takes a little while to happen?

I will be checking to see if I have less left string flatness as I come back to pianos...
