A DJ mixset is usually performed live in front of an audience in a nightclub, party, or rave setting. Mixsets can also be performed live on radio or recorded in a studio. Methods of mixing vary slightly depending on the music genres being played. House and trance DJs tend to aim for smooth blended mixes while hip-hop djs may use turntablism, scratching and other cutting techniques. Some DJ, particularly those mixing Goa trance may prefer to mix during a break in which instead of beats, washes of synthesized sounds are combined. Further refinement to the mixing quality can be provided with harmonic mixing which avoids dissonant tones during a mix.

Fun Facts :

DJs use equipment that can play at least two sources of recorded music simultaneously and mix them together. This allows the DJ to create seamless transitions between recordings and develop unique mixes of songs. Often, this involves aligning the beats of the music sources so their rhythms do not clash when they are played together.
