How can one musician record a whole band?
A recording can contain singing, guitar and drums made by the same person at different times. Recording software keeps the parts on separate tracks. Each track has its own place along a shared timeline, rather like several rows of a story that unfold together.
The musician can record a drum part first, then listen to it through headphones while adding guitar. A later vocal recording joins the same timeline. Hearing the earlier parts helps the musician match their timing. Recording a new part while earlier parts play is called overdubbing.
The shaded blocks show when recorded parts play, not how loud they are. The final two bars represent left and right output channels.
The separate tracks make mixing possible. If the guitar hides the words, its level can be lowered without making the voice quieter too. A pan control changes how much of a track goes to the left and right outputs, helping arrange the sounds across a stereo picture.
When the song is exported as an ordinary stereo recording, the chosen track signals are combined into left and right channels. The listener hears the finished combination. Keeping the original separate tracks lets the maker return later and change the balance. A song that sounds like one shared moment may have been built from many carefully connected moments.
About this explanation
The diagram isolates the main signal paths; actual equipment can add more tracks, effects and controls.
Starting knowledge: Recognize recorded sound, speakers and separately played musical parts.
