Words Mix-a-Mash uses

These are the words the app and the guides use, with a short meaning for each.

The mix

Lane: Live Mix has three lanes, the violet Main songs lane, the purple Section vocals lane and the pink Line vocals lane. You hear one lane at a time, the one with the bright border.
Mashup: The vocals of one song over the instrumental of another. You hear a mashup when you tap the pink or purple lane on Live Mix.
Mix: The music the host plays, built from their library as it plays. Friends join the mix from their phones.
Opening song: The first song of a mix. The mix picks it unless the host chooses one in Library, and it can be changed only while the mix is stopped at the start.
Part: One stretch of the mix. The mix is a chain of parts, and it plans a few parts ahead of what you hear.
Request: A song someone asked the mix to work in. The Requests guide says how.
Row: The top or bottom half of a lane. Each lane holds its blocks in two rows.
Song change: The point where the mix moves from one song to the next. Live Mix draws it as a block with two covers, and the block's details call it a "Transition".
Theme: A few words that describe a mood, such as "midnight jazz, neon city". The host sets it on Home by tapping the theme and choosing "Set", and the mix leans toward it.

Getting ready: A song that is still being read and split into vocals and an instrumental. The app shows "Getting ready" on it while that happens.
Instrumental: A song without its vocals. A mashup puts one song's vocals over another song's instrumental.
Main songs: Songs that play as themselves. Main songs is also the name of the violet lane on Live Mix, one of the two mix sources and a column on Requests.
