Which note is found at the open 3rd (G) string?

The open 3rd string on a standard-tuned guitar corresponds to the note G. When you pluck the 3rd string without pressing down on any frets, it vibrates at a frequency that produces the G note, which is situated at the middle of the musical alphabet.

Understanding the notes along the guitar strings can significantly enhance a player's ability to locate other notes, play scales, and form chords. In standard tuning, the strings from the lowest (6th) to the highest (1st) are tuned to E, A, D, G, B, and E. Recognizing the note at each open string is fundamental in mastering the guitar fretboard and aids in the overall learning and playing process.
