¿Cómo se llama la nota más grave del piano?

A standard 88-key piano spans just over 7 octaves (specifically, about 7.25 octaves).

Here is how the keys break down across the keyboard:

• The Sub-Contra Notes (3 keys): A0, Bb0, and B0 sit below the lowest full octave.

• The Full Octaves (7 octaves): C1 through C7 cover the primary body of the keyboard, containing 12 notes per octave (7 white keys, 5 black keys).

• The Final Note (1 key): C8 sits at the very top of the keyboard, completing the 88th key.

Because a standard piano starts on A0 and ends on C8, it gives musicians a massive range—from deep, rumbling bass frequencies around 27.5 Hz up to sparkling high trebles around 4,186 Hz!
