Task: Question Answering
Input (English): Passage: By the end of the 1960s, Ornette Coleman had become one of the most influential musicians in jazz after pioneering its most controversial subgenre, free jazz, which jazz critics and musicians initially derided for its deviation from conventional structures of harmony and tonality. In the mid-1970s, he stopped recording free jazz, recruited electric instrumentalists, and pursued a new creative theory he called harmolodics. According to Coleman's theory, all the musicians are able to play individual melodies in any key, and still sound coherent as a group. He taught his young sidemen this new improvisational and ensemble approach, based on their individual tendencies, and prevented them from being influenced by conventional styles. Coleman likened this group ethic to a spirit of "collective consciousness" that stresses "human feelings" and "biological rhythms", and said that he wanted the music, rather than himself, to be successful. He also started to incorporate elements from other styles into his music, including rock influences such as the electric guitar and non-Western rhythms played by Moroccan and Nigerian musicians.Of Human Feelings was a continuation of the harmolodics approach Coleman had applied with Prime Time, an electric quartet introduced on his 1975 album Dancing in Your Head. The group comprised guitarists Charlie Ellerbee and Bern Nix, bassist Jamaaladeen Tacuma, and drummers Ronald Shannon Jackson and Denardo Coleman, Ornette Coleman's son. Tacuma was still in high school when Coleman enlisted him, and first recorded with Prime Time in 1975 for the album Body Meta, which was released in 1978. Tacuma had played in an ensemble for jazz organist Charles Earland, but Earland dismissed him as he felt audiences gave excessive attention to his playing. Coleman found Tacuma's playing ideal for harmolodics and encouraged him not to change. Although Coleman's theory initially challenged his knowledge and perception of music, Tacuma came to like the unconventional role each band member was given as a soloist and melodist: "When we read Ornette's music we have his notes, but we listen for his phrases and phrase the way he wants to. I can take the same melody, then, and phrase it like I want to, and those notes will determine the phrasing, the rhythm, the harmony – all of that.". 
Question: What is the last name of the person who wanted his music, rather than himself, to be successful?
Output (English): Coleman.
