[EN] 230,380. Maendler, K. March 17, 1924, [Convention date]. Harps. - Chromatic strings are arranged in one plane, or adjacent parallel planes and are spaced similarly to the kevs of a pianoforte keyboard, i.e. equidistantly except for the gaps at the diatonic semitones as shown, the diatonic strings being equidistant from one another. The strings corresponding to the black notes of the keyboard may be differently coloured. At the lower end the strings are attached to a plate 13 extending over the soundbox 14. |
