four-track recording

Four-track recording is a method of recording music using a device with four separate channels or "tracks" to record individual sounds or instruments. Each track can capture a different audio source, such as vocals or instruments, allowing multiple recordings to be made separately. Once recorded, these tracks can be mixed together to create the final song. This technique was common in the 1950s and 1960s, especially with tape recorders, enabling musicians to build up multi-layered recordings gradually by recording over existing tracks.
