Core Thesis
The comparison matters because brightness is a tonal posture. Transient sharpness is an attack posture. They often co-occur, but they solve different listener questions.
Where the signals diverge
Brightness is a tonal posture. Transient sharpness is an attack posture. They often co-occur, but they solve different listener questions.
What to read first
Read spectral brightness first when the record feels veiled or abrasive tonally. Read transient sharpness first when the energy feels slow, blunt, or overly spiky.
How to read them together
Together they explain why some records sound bright but still feel soft, and why others feel aggressive without actually being bright.
