Hi Dave I've tuned a few old German pianos with four string unisons in the top treble - you can get an upright style rubber mute in between the narrower strings fairly easily. I've never had to check gauges here but maybe the extra string allows for a slightly lower tension while increasing volume..

The strings were pretty rusted, though at pitch, and tunable(despite having been installed more sloppily than I've ever seen). I didn't get to tune the whole thing, just looked it over a bit. The interesting feature is the four string unisons above the treble/tenor strut. I wish the piano was in good shape so I could really evaluate what musical effect this would create. Has anyone on this list come across one of these in decent condition? Tuning them must be a bit of a challenge. The strings of each note are so close together, that they seem quite difficult to get a mute between. Just another of life's interesting pianos. Dave Stahl
