Level 4 Checkpoint
Confirm that you can read C, G, and F major while applying accidentals in the right order.
Name the key
Before playing, say whether the exercise is in C major, G major, or F major. That tells you which letters may change.
Check altered notes
Watch F in G major and B in F major. Then apply any accidental that appears inside the measure.
Guided walkthrough
Use the checkpoint to prove that key signatures and accidentals happen in the correct order.
- 1Name the key before reading notes.
- 2Apply the key signature to the matching letter.
- 3Override it only when an accidental appears.
Try it on the keyboard
Play a short C major, G major, and F major fragment, naming the changed letter each time.
- 1C major: no changed letters.
- 2G major: F-sharp.
- 3F major: B-flat.
Common mistake
Many mistakes come from carrying the previous key into the next exercise.
Check yourself
Can you say the active changed letter before each fragment begins?
覚えておくこと
The right order is clef, key signature, accidental, then keyboard.
