Find Key Signature: How Many Sharps or Flats

The short answer: Find Key Signature gives you a key and asks for its signature — how many sharps or flats. Points scale with speed. It is the Circle of Fifths as a memory game, since the circle is the map of every key signature.

What the game is

You are handed a key and answer its sharp or flat count as fast as you can. Do enough rounds and the circle-of-fifths order stops being something you reason through and becomes something you simply recall.

What it teaches

• Every major key's signature at a glance.
• The circle-of-fifths order that generates them.
• The sharp/flat count you need to read and write in any key.

Why it's cool

Key signatures feel like rote memorization until the circle reveals them as a simple pattern — one more sharp each step clockwise, one more flat each step back. Then they are almost free.
