Which note is located on the 2nd fret of the 4th string?

The note located on the 2nd fret of the 4th string is indeed A. This is due to the standard tuning of the guitar, where the 4th string is tuned to D. Fretting this string at the 2nd fret raises the pitch by a whole step, resulting in the note E. However, if the question intended to suggest playing the 2nd note of a musical scale or another context, clarification would be necessary.

To understand the guitar fretboard and the relationships between notes, it is vital to memorize the notes on each string. The 4th string (D) played open is the root note, and as you move up to the 2nd fret, you reach E. In this fundamental learning, associating fret numbers with notes across the strings builds the essential knowledge for navigating the fretboard effectively.

While another note series may be offered, knowing the fretboard layout allows for an accurate identification of the notes across different positions, which is crucial for mastering rhythm and lead playing.
