The process[edit]

Click tracks (i.e. metronome recordings at a certain tempo) are often used to keep the musicians in perfect time; these can be played in musicians' ears through headphones, and so, barring any bleed, will not be picked up by the microphones and thus be silent on the final track.


In bands, different groups have different orders of recording instruments. Some record the entire group at the same time, as would be played in a live performance, though this can cause some instruments to be picked up on the microphones of others, which can complicate mixing: partition screens are available to counter this. Others choose to add tracks one by one. For example, a group may choose to have the drum and bass guitar record first, so that the following instruments keep in time, and can play to a better 'feel' of the song. Vocals are usually added last, only followed by backing vocals or solos, which may change or be complicated, meaning that multiple attempts could be useful before deciding on a final.^[2]


Scratch tracks are tracks that are played through roughly at first, so other musicians have something to work with, and can play to support the other parts. However, it is not final, and once the other musicians have recorded their parts, it will be rerecorded, when the musician will be able to play against the strengths of the parts already recorded, and have a better grasp of the feel of the music. In the previous example, the bass guitar part that was recorded first might just be a scratch track, to help the drummer get a feel of where emphasis and space in the song is.^[3]
