Which fret on the 3rd string is the note B?

The note B on the 3rd string (G string) of the guitar can be found on the 4th fret. This is because the notes on the guitar strings follow a specific order, progressing in whole and half steps.

Starting from the open G string, which is the 3rd string, you can determine the notes as follows:

• The open string is G.

• The 1st fret raises it to G# (or Ab).

• The 2nd fret is A.

• The 3rd fret is A# (or Bb).

• The 4th fret is B.

Thus, the note B is located on the 4th fret of the 3rd string. This systematic approach of moving up the fretboard by fretting each note helps in the understanding of the fretboard layout and strengthens one's ability to recognize notes effectively.
