Construction
It is constructed on the principle of the grand piano. A massive frame is shaped like a snooker table. The instrument has five notes; each note has six strings (three are tuned to the fundamental pitch, and three an octave higher). The strings are struck by large hammers, covered with cotton-wool, which the performer sets in motion by a strong elastic blow from his or her fist, similar to the motion of playing a carillon.
The hammers are attached to arms 22 inches (56 cm) long, which are screwed to a strong wooden span bridge placed horizontally above the strings at about two-fifths of the length from the front. On the point of the arm is the name of the note, and behind this the felt ledge struck by the fist. Two belly bridges and two wrest-plank bridges, one set for each octave, determine the vibrating length of the strings, and the belly bridge, as in other stringed instruments, is the medium through which the vibrations of the strings are communicated to the soundboard. The arrangement of pegs and wrest-pins is much the same as on the piano.

Famous quotes containing the word construction:
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“Striving toward a goal puts a more pleasing construction on our advance toward death.”
—Mason Cooley (b. 1927)
“The construction of life is at present in the power of facts far more than convictions.”
—Walter Benjamin (1892–1940)
