Which note corresponds to the 7th fret on the 4th (D) string?

The note that corresponds to the 7th fret on the 4th (D) string is actually B. To understand this, it's important to look at the notes on the D string and how the fretboard is laid out.

Starting from the open D string, the notes are as follows:

• Open 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

The progression of notes on the D string follows the musical alphabet, which repeats every 12 frets, meaning there are 12 unique notes before the pattern starts over again. Therefore, when counting up from the open D string, the note at the 7th fret is A.

Understanding the arrangement of notes on the fretboard is critical for navigating and identifying notes effectively while playing, so it's essential to incorporate this knowledge into practice.
