What note is located at the 3rd fret of the 2nd (B) string?

The note found at the 3rd fret of the 2nd (B) string is D. To understand why it’s D, it’s important to recognize how the musical notes progress on the guitar fretboard.

Starting from the open B string, if you move up to the 1st fret, you play C. Moving to the 2nd fret raises the pitch to C#, and finally, at the 3rd fret, the note changes to D.

This pattern follows the sequential nature of musical notes on a guitar. The notes advance in half steps, and knowing the sequence of notes helps in determining the note at each fret position. In this case, starting from B and counting the notes leads directly to D at the 3rd fret of the B string.
