Editing Harp (section)

=== Chromatic-strung harps ===
Some harps, rather than using pedal or lever devices, achieve chromaticity by simply adding additional strings to cover the notes outside their diatonic home scale. The Welsh triple harp is one such instrument, and two other instruments employing this technique are the [[cross-strung harp]] and the [[inline chromatic harp]].

The cross-strung harp has one row of diatonic strings, and a separate row of chromatic notes, angled in an "X" shape so that the row which can be played by the right hand at the top may be played by the left hand at the bottom, and vice versa. This variant was first attested as the ''arpa de dos órdenes'' ("two-row harp") in Spain and Portugal, in the 17th century.<ref name="MikishkaMusic1989">{{Cite book |last=Mikishka |first=Patricia O. |url=https://books.google.com/books?id=h3g9AQAAIAAJ |title=Single, double, and triple harps, 1581–1782: Harps having two or three rows of parallel strings.

The inline chromatic harp is generally a single-course harp with all 12 notes of the chromatic scale appearing in a single row. Single course inline chromatic harps have been produced at least since 1902, when [[:de:Weigel-Harfe|Karl Weigel]] of [[Hanover]] patented a model of inline chromatic harp.<ref name="Society1903">{{Cite book |title=Zeitschrift |collaboration=International Musical Society |date=1903 |publisher=Breitkopf und Härtel |page=[https://books.google.com/books?id=9Vw5AAAAIAAJ&pg=PA196 196]}}</ref>
