There are 88 keys on a standard piano.
Explanation:
The piano is a musical instrument that produces sound by pressing keys. Each key on a piano represents a specific pitch or note. The number of keys on a piano can vary, but the standard number of keys on a piano is 88.
The keys on a piano are organized in a repeating pattern of white and black keys. The white keys represent the natural notes (A, B, C, D, E, F, G), while the black keys represent the sharps or flats of those notes. The black keys are shorter and narrower than the white keys.
The pattern of black and white keys repeats across the entire piano keyboard. Starting from any C note, you will find a sequence of 7 white keys (C, D, E, F, G, A, B) followed by 5 black keys (sharps/flats of the previous white keys). This pattern keeps repeating until the highest note on the piano.
Now, let's calculate the number of keys based on this pattern.
- The lowest note on a standard piano is A0, and the highest note is C8.
- The pattern of 7 white keys and 5 black keys repeats 7 times across the piano keyboard.
- Each repetition includes 12 keys (7 white keys + 5 black keys).
- The first repetition starts with the note A0 and ends with G#0.
- The last repetition starts with the note C8 and ends with B8.
To calculate the number of keys, we need to count the keys in the first and last repetition:
- In the first repetition, there are 7 white keys + 5 black keys = 12 keys.
- In the last repetition, there are 7 white keys + 5 black keys = 12 keys.
Now, we can calculate the total number of keys:
- Counting the keys from A0 to G#0 (first repetition): 12 keys.
- Counting the keys from A0 to C8 (7 repetitions): 7 repetitions x 12 keys = 84 keys.
- Counting the keys from C8 to B8 (last repetition): 12 keys.
Adding all the keys together: 12 + 84 + 12 = 108 keys.
However, we need to consider that the lowest 20 keys on a piano are not considered standard keys and are not included in the count. These keys are used for extra notes and effects, but they are not part of the standard range.
Therefore, the total number of keys on a standard piano is 88 (108 keys - 20 extra keys).

The correct answer is option 'C' - 88 keys.
The piano is a popular musical instrument that is played by pressing keys. These keys produce different sounds when pressed, allowing musicians to create beautiful melodies and harmonies. A standard piano typically has 88 keys, which are arranged in a specific pattern.
Here is a breakdown of the keys on a standard piano:
1. White Keys:
- There are 52 white keys on a piano.
- These keys are named after the first seven letters of the alphabet: A, B, C, D, E, F, and G.
- The pattern of white keys repeats throughout the piano, starting from the lowest note and moving up in pitch.
- Each set of seven white keys represents an octave, which is a musical interval.
2. Black Keys:
- There are 36 black keys on a piano.
- These keys are raised and narrower than the white keys.
- The black keys are arranged in groups of two and three between the white keys.
- Each black key has two possible names, depending on its context in the musical scale.
3. Octaves:
- As mentioned earlier, each set of seven white keys represents an octave.
- An octave consists of a pattern of whole and half steps in the musical scale.
- The pattern of black keys repeats every octave as well.
- The lowest note on a standard piano is A0, and the highest note is C8, covering a range of seven and a quarter octaves.
4. 88 Keys:
- The 88-key piano has become the standard for most pianos, including acoustic and digital pianos.
- The additional keys beyond the 66-key and 48-key options allow for a wider range of musical expression.
- The full range of the piano enables musicians to play a wide variety of musical genres and styles.
In conclusion, a standard piano has 88 keys, consisting of 52 white keys and 36 black keys. The arrangement of these keys allows musicians to create music across a broad range of pitches and tones.
