Reading in G major · From Zero to Mozart

This is where Movement A's hand meets Movement B's eye. One sharp in the signature — every F is F♯ — read by interval, land the high 2 on the D string.

The octave, read one note at a time

60 bpm

G major, open G to the octave above, crossing strings at open D. Not a scale you hum — a real decode each time: symbol, name, apply the key, string, finger.

A phrase — and F♯ every time

58 bpm

Every F here is F♯ — high 2 on the D string — because the signature says so, even though no sign is printed next to it.

The same phrase, fighting the key

58 bpm

Now with F natural — low 2, pulled back. Against a G-major ear it sags. This is the note the key signature was protecting you from.

The usual mistake

Playing low 2 for F — the natural — where G major wants F♯, the high 2. In a one-sharp key, your 2nd finger lives forward on the D string.

Try

Play the phrase from the notation, F♯ every time. Then the natural version. Then back to F♯. Let your ear, not the label, tell you which one G major wants.
