What is the note on the 4th fret of the 6th (low E) string?

To determine the note on the 4th fret of the 6th (low E) string, it helps to understand the layout of the guitar fretboard and how frets represent half-step intervals. The open 6th string is E. As you move up the fretboard, each fret represents a half-step increase in pitch.

• Starting with the open E (0th fret), the note on the 1st fret is F (1 half-step up).

• The note on the 2nd fret is F# (2 half-steps up),

• The note on the 3rd fret is G (3 half-steps up),

• Finally, the note on the 4th fret is G# (4 half-steps up) or indeed F#.

Thus, since the question specifically asks for the note on the 4th fret, it would be F#. Understanding the incremental nature of how notes progress along the fretboard helps in identifying notes accurately and reinforces the concept of musical intervals. The correct selection reflects the proper application of this fundamental fretboard knowledge.
