Question: Daron Vartan Malakian (Armenian: Taron/Taron Vardan Malak`ean, born July 18, 1975) is an Armenian-American singer-songwriter, multi-instrumentalist, and record producer. He is best known as the guitarist, songwriter and second vocalist of the heavy metal band System of a Down and as the lead vocalist, lead guitarist and songwriter of the band Scars on Broadway. Daron Malakian is known for his distinctive playing and is ranked 40th in Loudwire's list of Top 50 Hard Rock + Metal Guitarists Of All Time and #11 in MusicRadar's poll, The 20 Greatest Metal Guitarists Ever.

In 2003, Daron Malakian (lead guitar and vocals), Greg Kelso (rhythm guitar), Casey Chaos (vocals), and Zach Hill (drums) recorded a demo tape entitled Ghetto Blaster Rehearsals, credited to the name Scars on Broadway. However, in 2007, an official letter appeared on the band's website that stated that these tracks are not in any way affiliated with Malakian's later project Scars on Broadway. Incidentally, these demo sessions produced "B.Y.O.B.", which would be a major hit for System of a Down in 2005.  Following System's hiatus, Malakian announced his latest project - Scars on Broadway - a band which would include System of a Down bassist, Shavo Odadjian, and himself. Ultimately, Odadjian was not involved with the band, and instead System of a Down drummer, John Dolmayan became a member. After Malakian and Dolmayan experimented with different musicians (for a period of nine months in 2007 - 2008) the band took form and forged its sound in intense rehearsals and recording sessions (under Malakian's direction at his home studio and Sunset Sound) with musicians Danny Shamoun on keyboards, Dominic Cifarelli on bass, and Franky Perez on guitar and backing vocals for live performances (in the studio Malakian played nearly all the instruments with the exception of drums which were played by Dolmayan and some overdubs provided by the other members). The group released an eponymous album in 2008, which featured the hit single "They Say" (written by Malakian). However, shortly before the tour supporting the album, Malakian cancelled all scheduled concert and TV appearances, blaming a lack of enthusiasm and that his "heart wasn't into touring." This sudden cancellation prompted speculation and rumors that the band had broken up. It was the last that would be heard of Malakian for more than a year.  In August 2009, Scars on Broadway, minus Malakian, traveled to Iraq for a USO tour across the U.S. army bases. Their setlist consisted of covers as well as a few Scars songs. Guitarist/vocalist Franky Perez stated on his Twitter that "the Scars tunes sound amazing but they're not the same without D..." He also stated before they left that Malakian had given them his blessing. In 2009 Franky Perez mentioned on his Twitter that he and the D-Man (Malakian) were going into studio to jam, this was the first news people have heard about Malakian's whereabouts for about a year.  On May 2, 2010, Malakian reunited with Scars on Broadway at the Troubadour in West Hollywood. It was the first time he had performed with the band since October 2008. The group played songs from their album as well as new songs. Odadjian performed with the band for two songs, playing guitar.  On February 24, 2012, System of a Down announced that the Scars on Broadway website is back online featuring a preview of a new song called "Guns Are Loaded".

Answer: It was the last that would be heard of Malakian for more than a year.

Problem: 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.
