These piano temperament strips are 100% wool, and are the most efficient way of setting a temperament. It is used to mute off the outside strings so one string can be tuned at a time. One strip is more than enough to strip the middle two octaves. Otherwise, in most pianos 2 strips would be enough to mute all but one string on each note for the entire piano. The strips are 50" L x 3/4" W tapering to 1/2" W.
American made, these are the highest quality available--same as the pros use!
Termperament Thickness:
Standard Temperament Strip: .165" thick.
Thin Temperament Strip: .135" thick. (If you are tuning an upright piano, get this thinner one).
What is a temperament strip?
The temperament strip is a long strip of wool felt with which you can mute many strings at once. It is used to mute all the outside strings of a section of notes so that only one string from each note can vibrate at a time. Push it between strings with a screw driver. That way you can efficiently tune one string in each note without having to move rubber wedges every time you change notes. After tuning all the single strings, tune the unisons by selectively pulling the temperament strip out or using wedges. Place it once, and tune the entire octave! This is actually the "professional" procedure, especially for setting the temperament (hence the name), though each tuner has preferences for when to use what mute.
