What note is played on the A string at the 2nd fret?

On the A string of a guitar, the open string itself is tuned to the note A. When you press down on the 2nd fret of the A string, you raise the pitch by two half steps (also referred to as two semitones). The notes are as follows:

• The 1st fret corresponds to A# (or Bb).

• The 2nd fret corresponds to B.

Therefore, the note played on the A string at the 2nd fret is B. This understanding of fret positioning is crucial for navigating the fretboard and recognizing notes based on their relationship to the open strings.
