What note is located on the D (4th) string at the 4th fret?

The note located on the D (4th) string at the 4th fret is F#. Understanding how to identify notes on the guitar fretboard is essential for learning and playing.

When you play the D string, the open note is D. As you move up the fretboard, each fret represents a half step (or semitone) on the musical scale. By counting up from D, you get the following sequence:

• 1st fret: D# (or Eb)

• 2nd fret: E

• 3rd fret: F

• 4th fret: F#

Thus, at the 4th fret, the note is F#. This systematic approach to understanding the fretboard helps in recognizing and memorizing the notes quickly, allowing for more fluid playing and improvisation on the guitar.
