Identify the note located at the 3rd fret of the 2nd (B) string.

To determine the note located at the 3rd fret of the 2nd (B) string, we can reference the standard tuning of the guitar. The standard tuning for the B string, which is the second string, is a B note.

When you press down at the 1st fret of the B string, it raises the pitch to C. Pressing down at the 2nd fret raises it further to C#. Thus, when you reach the 3rd fret, the pitch is raised to D.

Recognizing this sequence is key to navigating the fretboard. Starting from the open string B, you can follow the chromatic scale (B, C, C#, D) to find that the note at the 3rd fret is indeed D. Understanding this pattern helps in identifying notes across the fretboard, making it easier to play scales and chords.

This reasoning based on standard tuning and the chromatic scale allows guitarists to accurately identify notes on each string and fret.
