Question:
Harry Partch (June 24, 1901 - September 3, 1974) was an American composer, music theorist, and creator of musical instruments. He composed using scales of unequal intervals in just intonation, and was one of the first 20th-century composers in the West to work systematically with microtonal scales. He built custom-made instruments in these tunings on which to play his compositions, and described his theory and practice in his book Genesis of a Music (1947). Partch composed with scales dividing the octave into 43 unequal tones derived from the natural harmonic series; these scales allowed for more tones of smaller intervals than in standard Western tuning, which uses twelve equal intervals to the octave.
Partch made public his theories in his book Genesis of a Music (1947). He opens the book with an overview of music history, and argues that Western music began to suffer from the time of Bach, after which twelve-tone equal temperament was adopted to the exclusion of other tuning systems, and abstract, instrumental music became the norm. Partch sought to bring vocal music back to prominence, and adopted tunings and scales he believed more suitable to singing.  Inspired by Sensations of Tone, Hermann von Helmholtz's book on acoustics and the perception of sound, Partch based his music strictly on just intonation. He tuned his instruments using the overtone series, and extended it past the twelfth partial. This allowed for a larger number of smaller, unequal intervals than found in the Western classical music tradition's twelve-tone equal temperament. Partch's tuning is often classed as microtonality, as it allowed for intervals smaller than 100 cents, though Partch did not conceive his tuning in such a context. Instead, he saw it as a return to pre-Classical Western musical roots, in particular to the music of the ancient Greeks. By taking the principles he found in Helmholtz's book, he expanded his tuning system until it allowed for a division of the octave into 43 tones based on ratios of small integers.  Partch uses the terms Otonality and Utonality to describe chords whose pitch classes are the harmonics or subharmonics of a given fixed tone. These six-tone chords function in Partch's music much the same that the three-tone major and minor chords (or triads) do in classical music. The Otonalities are derived from the overtone series, and the Utonalities from the undertone series.

Question:
Jean-Marie Le Pen (French pronunciation:  [Za ma.Ri l@.pen]; born 20 June 1928) is a French politician who has served as Honorary President of the National Front since January 2011 and a Member of the European Parliament (MEP) from France since 2004, previously between 1984 to 2003. He previously served as President of the National Front from 1972 to 2011.
Le Pen is often nicknamed the "Menhir", due to his "granitic nature" as he is perceived as someone who does not give way to pressure or who cannot be easily knocked down. It also connects him to France's Celtic origins. Le Pen is often described as one of the most flamboyant and charismatic orators in Europe, whose speech blends folksy humour, crude attacks and rhetorical finesse.  However, Le Pen remains a polarizing figure in France: opinions regarding him tend to be quite strong. A 2002 IPSOS poll showed that while 22% of the electorate have a good or very good opinion of Le Pen, and 13% an unfavorable opinion, 61% have a very unfavorable opinion.  Le Pen and the National Front are described by much of the media and nearly all commentators as far right. Le Pen himself and the rest of his party disagree with this label; earlier in his political career, Le Pen described his position as "neither right, nor left, but French" (ni droite, ni gauche, francais). He later described his position as right-wing and opposed to the "socialo-communists" and other right-wing parties, which he deems are not real right-wing parties. At other times, for example during the 2002 election campaign, he declared himself "socially left-wing, economically right-wing, nationally French" (socialement a gauche, economiquement a droite, nationalement francais). He further contends that most of the French political and media class are corrupt and out of touch with the real needs of the common people, and conspire to exclude Le Pen and his party from mainstream politics. Le Pen criticizes the other political parties as the "establishment" and lumped all major parties (Communist, Socialist, Union for French Democracy (UDF) and Rally for the Republic (RPR)) into the "Gang of Four" (la bande des quatre - an allusion to the Gang of Four during China's Cultural Revolution).
