The Sharp Lab
You already found one by ear in City Walls — that note between C and D. It has a name: . A sharp just means the very next key up. Most of the time, that next key is black.
White keys have names. So do the black ones.
Press any key to hear it. The white keys are C D E F G A B. The black keys are the sharps — the steps squeezed in between. Notice they come in a group of two, then a group of three. That pattern is your map.
C♯ is the black key glued to the right of C. Find the group of two black keys — C♯ is the left one of that pair. Every time.
Hear the half-step.
A sharp is the smallest move on the piano — one key, no skipping. Play C, then C♯, and listen to how close they sit.
On guitar you slide between them with the bend wheel. On piano you can’t land between — so the C♯ is that in-between note. That’s why the black key fixes City Walls.
Can you spot it on the keys?
Read the note name, then tap the right black key. It speeds through C♯, F♯, G♯, D♯, A♯ — the five sharps. Gets harder as you go.
Press start.
White key or sharp?
You’ve got the ear for this. A note plays — decide if it’s the plain white key or the sharp one step above it. Replay as many times as you want.
