Inline chromatic harp
An inline chromatic harp is a harp where the strings for all 12 chromatic notes of the octave are placed in one row, as opposed to their being placed in two or three courses.
At least one example of a harp with two parallel inline chromatic courses has also been produced.
Single course inline chromatic harps have been produced for at least the past 110 years: in 1902 :de:Weigel-Harfe|Karel Weigel of Hanover patented a model of inline chromatic harp. He built at least one 54 string model which is now housed in the Deutsches Museum.
A disadvantage of inline chromatic harps is that glissandi can only be performed chromatically.
