    "​Sixth-Tone Harmoniums ",
    "​The first type of sixth-tone harmonium was made in 1927 as a small collapsible instrument of the portable type without registers, i.e. single-read, in four octaves (C–c3) with two manuals. Hába registered it as the second item in his inventory of the conservatory’s quarter-tone department in 1935 (No. 10).14 In the former Music Division of the National Museum it was listed starting in 1970 together with a quarter-tone grand piano under the acquisition number 67; it bears the serial number 1572 and the Czech Museum of Music inventory number NM-ČMH E 1598. ",
    "​Another type of sixth-tone harmonium, from 1937, is a triple-reed instrument with five octaves (F1–f3) and three manuals, two knee levers for forte and Grand jeu, and the following six registers: ",
    "​ BASS Bassoon 16' Clarinet 8' Flute 4'  ",
    "​ DISCANT Bassoon 16' Clarinet 8' Flute 4'  ",
    "​Built in a case, this instrument bears the serial number 2125. In the museum it was registered chronologically under acquisition number 95/1987 and has the inventory number NM-ČMH E 2527.15 ",
    "​For the keyboards of sixth-tone instruments, whose octave is divided into thirty-six tempered tones, Hába had to produce a new and completely independent design. Here two whole-tone series, starting with F on the second manual and with F sharp on the first, are played on narrow, protruding keys. For each of these pitches there is also one pitch a sixth-tone higher and one a sixth-tone lower.16 In the case of the three-manual harmonium the third manual repeats the tones of the first, as in the quarter-tone keyboard instruments. "
