In the new book by Brian Capleton, "Theory and Practice of Piano Tuning" he says on p167 "Tuning only the middle string of each trichord makes the task of scale tuning quicker and easier. The unisons are then tuned afterwards. There is nothing in elementary theory to suggest that this might give a result different to tuning the scale trichord by trichord. In practice there are important differences, which is why expert tuners always proceed using a Papps wedge, tuning the unisons as the scale tuning proceeds, rather than using muting felt. Muting felt is, however, used in the learning process, until the trainee reaches the stage where wedge tuning can be undertaken. In order to tune the scale using a Papp's wedge, firstly there must be the ability to reliably tune excellent ans stable unisons, and secondly there must be some understanding of the raltionship between the sound of the unison and the sound of the tempered interval". I don't have a muting strip at all, but have always used a Papp's wedge (rubber wedge for grands). Best regards, David. "100% agree. Single mute tuning opens up new vistas of stability and precision; when it's practiced consistently, tunings get better, more musical, more "ringing," clearer. Your standard of listening, and of excellence, rise quickly. David Andersen"
