How to Find C on the Piano: Black Keys in Twos and Threes

A standard piano has 88 keys: 52 white and 36 black. There are eight Cs among them, and middle C is the fourth C from the left. In scientific pitch notation it is C4, and in the MIDI standard it is note number 60 (Wikipedia, “C (musical note)”).

To a child, 88 keys in a row all look the same. But the clue to finding C is on the keyboard itself: the way the black keys are arranged.

Black keys come in twos and threes

Look closely and you’ll see the black keys alternate between groups of two and groups of three.

C is the white key just to the left of a group of two black keys. I think this is the single most useful sentence.

From there, follow the white keys to the right.

• C: left of the two black keys
• D: between the two black keys
• E: right of the two black keys
• F: left of the three black keys
• G and A: between the three black keys
• B: right of the three black keys

After B comes the next C, to the left of the next pair. This group of seven white keys and five black keys repeats from one end of the keyboard to the other.

When explaining it to a child, I think it is enough to say, “Find two black keys. The key on their left is C.” There’s no need to learn D through B all at once. Once they can find C, they can walk up from it while singing.

Finding middle C

There are many Cs on a keyboard. The first one children learn is usually middle C, and many children’s method books start there.

On an 88-key piano, the fourth C from the left is middle C. It sits near the center of the keyboard, so one way to remember it is that a child sitting in the middle of the bench will find it roughly in front of their belly button.

Keyboards with fewer keys

If what you have at home is an electronic keyboard, take a little care. Many have fewer than 88 keys.

On a 61-key (five-octave) keyboard, the leftmost key is usually a C, and in that case middle C is the third C from the left. On small 49-key or 25-key MIDI keyboards, the range differs by model, and many have buttons that shift the octave up or down. On these, “the nth C from the left” is not reliable. The manual is the surest guide.

One more thing: some manufacturers and music software label middle C as C3 instead of C4. If the label on screen doesn’t match your method book, this is likely why.

Do-re-mi and C-D-E

Do, re, mi, fa, sol, la, ti (or si) are syllable names. In letter names they are C, D, E, F, G, A, B: do is C, re is D, mi is E, fa is F, sol is G, la is A, and ti is B. Many countries, Japan included, teach children do-re-mi first, while English-language method books often use letters from the start.

I don’t think a young child needs both systems at once. Use whichever your child’s teacher or book uses. Still, it helps if the parent knows how they match, because keyboards, apps and chord names will show letters.

Games for learning where C is

Here are some games I’d recommend.

• Find every C. Go from the left end to the right end and press every C. The pitch changes, but the ear can tell they are all “C.”
• Find the pairs. Press each group of two black keys with the index and middle fingers together. Playing only black keys already sounds like music.
• Find it with eyes closed. Close your eyes, feel the black keys with your fingers, and find a group of two. Being able to place a finger on C without looking helps later when reading music while playing.
• Sing your way up. Starting from C, press the white keys in order while singing “do, re, mi, fa, sol, la, ti, do.”

You can also put stickers on the keys. If you do, I’d use one sticker on middle C only, and only for the first few days. When every key has a name, there’s no reason to look at the black key pattern anymore.

On the Kinder Piano keyboard

Kinder Piano is a piano app for iPhone and iPad for children from about age 3 to the early years of primary school. I made it for my 4-year-old daughter.

The on-screen keyboard normally has no note names on the keys. A child finds C by looking at the groups of two and three black keys, the same way they would on a real piano. On the practice screen, the next key to press lights up, so a child can start playing before knowing where C is. When a key lights up, it helps if a parent says out loud where it is, like “left of the two black keys.”

Once your child knows C, the ear training levels that compare notes with C become useful. The child hears C first and then names the next note by pressing it, and in these levels middle C is marked on the keyboard. The first ear training level, which uses C, E and G, is free.

In Free Play, you can choose between an Easy and a Normal keyboard. Easy shows large keys from middle C up to the E an octave above, which suits the find-the-C games.

All 21 nursery songs are free, and the first classical piece and the first ear training level are free too. A one-time purchase opens the rest of the classical pieces and every ear training level. There are no ads and no subscription. Connect a MIDI keyboard and your child can look for C on real keys (How to Connect a MIDI Keyboard to an iPad or iPhone).
