What note corresponds to the 4th string 8th fret?

To determine the note that corresponds to the 4th string at the 8th fret, it is essential to understand the tuning of the guitar strings and how the frets represent different notes.

The 4th string on a standardly tuned guitar is a D string. When you play a note on a fret, you are essentially raising the pitch of the open string by a half-step for each fret you move up.

Starting with the open 4th string (D):

• 1st fret = D# (or Eb)

• 2nd fret = E

• 3rd fret = F

• 4th fret = F# (or Gb)

• 5th fret = G

• 6th fret = G# (or Ab)

• 7th fret = A

• 8th fret = A# (or Bb)

Since you are on the 8th fret of the 4th string, the note you find there is A#. This aligns perfectly with our understanding of how the fretboard notes progress, confirming that the correct answer is A#.
