Beginning violin students must learn how to play all the different notes on the violin's four strings. The four strings are E, A, D and G. There are four ways to play an F note on a violin. There is an F natural and F sharp on both the D and E string. Repetition will help you become comfortable with placing your fingers in the correct spots along the violin strings.
Position your index finger a whole step from the fingerboard on the E string to play an F sharp note. A whole step is about 1 inch.
Move your index finger low, next to the fingerboard, to play an F natural on the E string. Each finger can take a low or high position, with low positions being closer to the fingerboard.
Place your middle finger low on the D string to play an F natural note. Your index and middle fingers should almost be touching each other. This finger positioning is known as a half step.
Move your middle finger to the high position on the D string to play an F sharp note. Your index and middle fingers should have an inch between them (a whole step).
New students may want to place colored pieces of tape on the violin to show where their fingers should be placed for different notes.
