Which note corresponds to the 9th fret of the 3rd string?

The note at the 9th fret of the 3rd string on the guitar is actually the note B. To find the note corresponding to a specific fret on a string, it's important to remember the standard tuning of the guitar, particularly for the 3rd string, which is tuned to G in standard tuning.

Starting from G at the open 3rd string, you can move up the fretboard to determine the note associated with each fret. The progression goes as follows:

1. Open (0 fret) - G

2. 1st fret - G#

3. 2nd fret - A

4. 3rd fret - A#

5. 4th fret - B

6. 5th fret - C

7. 6th fret - C#

8. 7th fret - D

9. 8th fret - D#

10. 9th fret - E

Thus, at the 9th fret of the 3rd string, you arrive at the note B. Understanding how to move along the fretboard like this helps you find any note on any string effectively, making it easier to navigate the guitar neck.
