Which note corresponds to the 4th fret of the D (4th) string?

The note that corresponds to the 4th fret of the D (4th) string is F#. This is determined by understanding the standard tuning of the guitar and the sequence of notes on the fretboard. The D string, when played open, is a D note. As you move up each fret, you increase the pitch of that note by a half-step.

• From D, the 1st fret is D# (or Eb), the 2nd fret is E, and the 3rd fret is F. Therefore, the 4th fret, which is one half-step above F, is F#.

This systematic approach to identifying notes on the fretboard is essential for musicians as it helps in playing and understanding scales, chords, and melodies effectively. Recognizing the pattern of whole and half steps between notes aids in navigation across the fretboard while enhancing musical comprehension.
