What note is found on the 3rd fret of the 2nd string?

On a standard-tuned guitar, the 2nd string is the B string. When you press down on the 3rd fret of the 2nd string, you are raising the pitch of the B note found at the open string. Each fret on the guitar represents a half step in pitch. Therefore, moving up two half steps from B (the open string) takes you to the note D: B to C (1 fret) and then C to D (2nd fret). This is why D is the correct answer, as it is the note produced when playing the 3rd fret on the 2nd string. Understanding this relationship between frets and notes is key for navigating the guitar fretboard effectively.
