发明名称 Piano tuning mutes
摘要 A muting strip for use in tuning the un-wound three string unisons of the treble section in pianos consisting of a strip of muting material having on it a series of wedges spaced at a distance from each other so that they will fit into every other space between the unisons. In tuning, two mutes are used with one above the other and offset one unison so that all spaces between the unisons are muted as is normal. After the center string of each unison is tuned one of the mutes is removed and one outer string of each unison is tuned. Then the remaining mute is shifted over one space and the remaining strings are tuned.
