Justin Gordon Holt (19 April 1930 – 20 July 2009) was an audio engineer and the founder of Stereophile magazine, and is widely considered to be the founder of the high-end audio movement, which promoted the philosophy of judging sound quality by subjective tests, generally with "cost no object" sound components, including loudspeakers, turntables, amplifiers, vacuum tube components, cables, and other devices.
 Known as "JGH" (from his byline in published reviews and articles), Holt established a reputation for veracity, often-controversial opinions, passionate critiques, and journalistic integrity.
 He also pioneered the concept of the yearly "Recommended Components" list, providing a thumbnail summary of reviews for audiophiles looking for the finest sound components available at any price.
 Holt also came up with "Holt's Law," the theory that the better the recording, the worse the musical performance—and vice versa.
Music appreciation is teaching people what to listen for and how to understand what they are hearing in different types of music.
 In North America, music appreciation courses often focus on Western art music, commonly called "Classical music".
 Usually music appreciation classes involve some history lessons to explain why people of a certain era liked the music that they did.
 "Appreciation," in this context, means the understanding of the value and merit of different styles of music.
 Music appreciation classes also typically include information about the composers, the instruments and ensembles, and the different styles of music from an era.
 Music appreciation courses are widely available in universities and colleges.
 Typically, these courses are designed for non-music majors.
 A significant part of music appreciation courses is listening to recordings of musical pieces or excerpts from pieces such as symphonies, opera arias and concertos.
 In some music appreciation classes, the class may go out to hear a live musical performance by an orchestra or chamber music group.
