What note does the 9th fret of the 2nd string represent?

The 9th fret of the 2nd string, which is commonly referred to as the B string, represents the note C#. This can be understood by analyzing the musical notes on the fretboard.

The open 2nd string starts at B. Moving up the fretboard, each fret represents a half step (or semitone) increase in pitch. Therefore, the 1st fret is C, the 2nd fret is C#, the 3rd fret is D, and so forth. At the 9th fret, you have moved up eight half steps from B.

Counting those half steps from the open string:

• 1st fret: C

• 2nd fret: C#

• 3rd fret: D

• 4th fret: D#

• 5th fret: E

• 6th fret: F

• 7th fret: F#

• 8th fret: G

• 9th fret: G#

This counting confirms that the pitch at the 9th fret is indeed C#, making it the correct answer. Understanding the layout of the fretboard and how notes progress in half steps is crucial for mastering the instrument.
