Here’s a brief overview of a piano keyboard:

• Keys: A standard piano keyboard has 88 keys, which includes both white and black keys.

• White Keys: These represent the natural notes (A, B, C, D, E, F, and G). There are a total of 52 white keys.

• Black Keys: These are the sharp (#) and flat (b) notes. There are a total of 36 black keys, arranged in groups of twos and threes.

• Octaves: The keyboard is divided into octaves, each containing 7 white keys and 5 black keys. There are 7 full octaves and a few additional keys on a standard piano.

• Layout: The pattern of black and white keys repeats every 12 keys. This is known as an octave.

• Middle C: This is a key of reference, located roughly in the middle of the keyboard, and it’s often used as a starting point for beginners
