Keep the treble-reading process unchanged while applying F-sharp every time the letter F appears.
The key signature applies to every F, not only the first F or the pitch nearest the printed sharp. Your goal for this lesson is clear: Can you locate every F in the excerpt before playing and explain when an F-natural would be allowed?
Key signature
G Major
1 ♯ (F♯)
One sharp
G major uses one sharp: F-sharp. Read the staff letter first, then apply the key signature every time an F appears.
Before playing the illustration for “One sharp” (G4, A4, B4, C5, D5, E5, F#5, G5), state the active key and the letter changed by its signature or accidental. Point to every occurrence of that letter first, then read the remaining notes with the ordinary staff routine.
Same habit, different letter
G major asks you to watch F. F major asks you to watch B. The process stays the same: clef, staff position, key signature, then keyboard.
Key color and scale degree
In G major, F-sharp acts as the leading tone that wants to resolve to G. That gives the key its pull back home.
Accidentals in a sharp key
If a natural sign cancels F-sharp for a measure, obey the accidental first, then return to the G major key signature at the bar line.
Reading in G Major at the keyboard
Now take the idea to the keyboard. Play a short G-major phrase and pause before each written F to confirm that the black key is prepared.
- 1Play G-A-B-C-D without alteration.
- 2Continue E-F-sharp-G and identify the changed key.
- 3Repeat the full phrase without pausing while preserving every F-sharp.
