Adult contemporary musicAdult contemporary music (AC) is a form of radio-played popular music, ranging from 1960s vocal and 1970s soft rock music to predominantly ballad-heavy music of the present day, with varying degrees of easy listening, pop, soul, R&B, quiet storm and rock influence. Adult contemporary is generally a continuation of the easy listening and soft rock style that became popular in the 1960s and 1970s with some adjustments that reflect the evolution of pop/rock music.
Trap musicTrap is a subgenre of hip hop music that originated in the Southern United States in the 1990s. The genre gets its name from the Atlanta slang term "trap house", a house used exclusively to sell drugs. Trap music uses synthesized drums and is characterized by complex hi-hat patterns, tuned kick drums with a long decay (originally from the Roland TR-808 drum machine), and lyrical content that often focuses on drug use and urban violence. It utilizes very few instruments and focuses almost exclusively on snare drums and double- or triple-timed hi-hats.
Audio engineerAn audio engineer (also known as a sound engineer or recording engineer) helps to produce a recording or a live performance, balancing and adjusting sound sources using equalization, dynamics processing and audio effects, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "technical aspect of recording—the placing of microphones, pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer... the nuts and bolts.
Record producerA record producer is a music recording project's overall supervisor whose responsibilities can involve a range of creative and technical leadership roles. Typically the job involves hands-on oversight of recording sessions: ensuring artists deliver acceptable performances, supervising the technical engineering of the recording, and coordinating the production team and process. The producer's involvement in a musical project can vary in depth and scope. Sometimes in popular genres the producer may create the recording's entire sound and structure.
