Julius Bl\u00fcthner invented the aliquot stringing system in 1873. The Bl\u00fcthner aliquot system uses an additional (hence fourth) string in each note of the top three piano octaves. This string is slightly higher than the other three strings so that it is not struck by the hammer. Whenever the hammer strikes the three conventional strings, the aliquot string vibrates sympathetically. This string resonance also occurs when other notes are played that are harmonically related to the pitch of an aliquot string, though only when the related notes\u2019 dampers are raised. Many piano-makers enrich the tone of the piano through sympathetic vibration, but use a different method known as duplex scaling. Confusingly, the portions of the strings used in duplex scaling are sometimes called \u201caliquot strings\u201d, and the contact points used in duplex scales are called aliquots. Aliquot stringing and the duplex scale, even if they use \u201caliquots\u201d, are not equivalent.<\/p>\n
Because they are tuned an octave above their constituent pitch, true aliquot strings transmit strong vibrations to the soundboard. Duplex scaling, which typically is tuned a double octave or more above the speaking length, does not. And because aliquot strings are so active, they require dampers or they would sustain uncontrollably and muddy the sound. Aliquot stringing broadens the vibrational energy throughout the instrument, and creates an unusually complex and colorful tone. This results from hammers striking their respective three strings, followed by an immediate transfer of energy into their sympathetic strings. The noted piano authority Larry Fine observes that the Bl\u00fcthner tone is \u201crefined\u201d and \u201cdelicate\u201d, particularly \u201cat a low level of volume\u201d.The Bl\u00fcthner company, however, claims that the effect of aliquot stringing is equally apparent in loud playing.<\/p>\n
