Timbre
Same pitch, same loudness, and still unmistakably two different instruments
Related
Timbre is what makes the same pitch sound like two different instruments. Play A4 on a piano and a violin: the frequency is identical and the loudness can be matched, yet the ear separates them at once. The difference lies in the balance of partials (which overtones sit above the fundamental and how loud each is), the shape of the attack and decay (a hammer, a bow and a breath each leave a different onset), and the noise content (bow hair scraping, turbulent air).
So timbre is not a fixed label: change a string or shift to another position on the same violin and the colour changes.
The usual mistake is to confuse timbre with audio fidelity — the first is an instrument's sonic identity, the second is how faithfully a recording chain reproduces it. They are different things.
