Alois Hába

Haba behind a
one-sixth tone harmonium The Czech composer Alois Hába (b. Vizovice, Moravia, 21 June 1893, d. Prague, 18 November 1973) was, together with Leos Janácek and Bohuslav Martinu, the most distinctive figure in 20th-century modern Czech music.
He began his musical career in his childhood as a violinist, playing Moravian folk music in his father's folk band. His mother, Theresia Trckova, was an excellent folk singer who taught Hába peasant songs from the Valassko region, the intervals of which sometimes deviated from the semitone system. These folk songs, particularly those of his native East Moravia, were his first major and lasting influence. Later he developed his own archives of recorded folk songs which he then studied. He analysed the folk modal scales in the chapter entitled "Greek Scales and Folk Songs from the Slovacko District" in his book Neue Harmonielehre. Hába found in folk songs the first stimuli for the building of his modal and microtonal system in both musical theory and practice.
His traditional compositional training took him to Berlin and later to Vienna, where he proofread scores of Schönberg and Janácek for Universal Edition. He studied Schönberg's Harmonielehre, and read the essays on music and the Sketch of a New Esthetic of Music by Ferruccio Busoni of whose private musical circle in Berlin he was a member. From Schönberg, Hába adopted the principle of equality between dissonance and consonance. Both Hába and Schönberg considered the minor second, major seventh and other dissonances to be intervals equal to the consonant third, sixth, etc.
He began composing in quartertones after reading a newspaper article about them in 1917. Also just after World War I, and independently of Hába, the Russian Ivan Wyschnegradsky began composing in quartertones. They were the first composers who applied this means systematically and would continue to do so during the rest of their lives. Hába's first composition in the quartertone system is his Second String Quartet. Thanks to his account in his musical "autobiography" Mein Weg zur Viertel- und Sechsteltonmusik (Düsseldorf 1971) we know relatively much about its history of origin. The work was written in less than two weeks, during the spring of 1920, as in a flash. After some hesitation Hába decided to present his first quartertone composition to his teacher, Franz Schreker. He was quite surprised, asked if Hába had gone mad, but took a good look at it. Schreker was appointed as director of the Musikhochschule in Berlin shortly after and Hába and many of his fellow students followed him to Berlin. There the first performance of the Second String Quartet took place on 28 November 1922, by the Havemann-Kwartett.
Hába started and led a department of Microtonal Music at the Prague Conservatory from 1924 until 1951. He also created new instruments such as 1/4-tone pianos (1924-1931), 1/6-tone harmonium (1936, see photo), 1/4-tone clarinet (1924) and trumpet (1931), and finally a 1/4-tone guitar in 1943, for which he wrote several suites and a song cycle. He is easily the most prolific of twentieth century's microtonal composers, having written extensively for string quartet, orchestra and keyboards. He also wrote a fully-grown quartertone opera, The Mother (1930), about the life of the peasant population in the Moravian countryside.
Haba Another distinctive feature of Hába's music is his "athematism", denying the classical-romantic thematic work based on a stereotyped repetition of motifs, themes and larger structural units in the composition. Hába decided to adhere to these principles to extend the possibilities of expression. In his compositions, he works with unrepeated themes and motifs, the expressive effect of which he enhances with the help of tone differentiation (ranging from semitones to the finest fifth-tone microtones), a free selection and a logical thinking of intervals in distinctive musical ideas.
In his String Quartet in Fifth-tone System No. 16, op. 98 (1967), Hába assumed a new task, one which, in the genre of microtonal music, the Dutch school headed by physicist Adriaan Daniël Fokker (whom Hába met at the UNESCO Congress in Paris in 1958) and composer Henk Herman Badings had tried to solve before him and consisting in the adoption, as the basic unit of microtonal system of his composition, of the fifth-tone (1/31th of an octave, approximating Aristoxenos' diesis), i.e. an interval smaller than the quarter-tone from which it differs also in that it cannot be replaced enharmonically. Hába was convinced that by using the fifth-tones he could bridge the difference between this type of micro-interval music and the semitone system.

Alois Hába employed the quarter-tone guitar as accompaniment in several vocal compositions dating from the 1930s. The instrument soon captivated him so much that he wrote two suites for it, one at the end of 1943 and the other in the second half of 1947. A Prague guitarist Cisar did a trial performance of the fourth movement only of the technically demanding and musically complex quarter-tone guitar Suite No. 1. Hába the duly applied the experience acquired in the process while devising the much simpler form of the Suite No. 2 for quarter-tone guitar, op. 63. The Suite is athematic in terms of form. Its five movements' adherence to the uniform key of E minor (and the eponymous E major), rhythmic distinctiveness of the motives of its fast movements, and lyric tunefulness of the slow ones, account for the work's formal succinctness and accessibility. The melodies, which prevail over chordal treatment, make use of all 24 intervals of the quarter-tone scale.
