What is the note at the 0 fret (open) of the 5th (A) string?

The note at the 0 fret (open) of the 5th string, also known as the A string, is A. When a string is played open, it produces the note designated for that string, which corresponds to its tuning. In standard tuning for a six-string guitar, the 5th string is specifically tuned to the note A. This foundational understanding of string tuning is critical for guitarists as it serves as a basis for playing chords and melodies. Recognizing the open notes of each string is essential for navigating the fretboard and applying knowledge across different musical contexts.
