What Mastering Is
The final pass after the mix, shaping loudness, tone and peaks so a finished track holds up on many playback systems.

Mastering is the final pass after the mix is approved. It does not rewrite the arrangement or repair the mix.
The problem
A song that sits well on studio monitors can turn thin on a phone or in a car. Singles that sound fine alone may jump in level on one album.
Goals and standards
Mastering preserves the mix's proportions while unifying loudness, tone and true peak. A common approach sets one integrated LUFS target and keeps true peak near -1 dBTP, so lossy encoding does not clip. The result should be repeatable and survive phones, cars and headphones.
Practice
Listen through the mix and note low-end, dynamic and stereo issues. Make global changes only. Use EQ for tone and compression or limiting for peaks, then check loudness and true peak. Export a high-resolution master and a lossless version, and keep an unlimited copy.
What to listen for
Hear whether the low end stays tight, the vocal stays stable, loud passages turn harsh and quiet ones still exist. The piano phrase checks attack and tail.
Common misunderstandings
Mastering cannot rescue a mix; frequency clashes belong in the mix. It is more than a limiter, since it includes tone, sequencing and delivery. Louder is not better, because platforms normalise loudness.
