Which note is played on the 3rd fret of the 6th (low E) string?

The note played on the 3rd fret of the 6th (low E) string is G. When tuning a standard guitar, the E string is the lowest sounding string, and when you press down on the 3rd fret, you raise the pitch of that string by a whole step and a half.

To understand the relationship of the frets to musical notes on the guitar, it can be helpful to know the order of notes in standard tuning. Starting from E, you go up a half step (1 fret) to F at the 1st fret, and then to F# at the 2nd fret, and finally to G at the 3rd fret. Therefore, pressing down the 3rd fret on the 6th string results in producing the note G.

This knowledge is fundamental for navigating the fretboard and understanding the relationship between various notes, which will greatly assist in learning scales, chords, and music theory.
