What chord is associated with the 9th fret of the 2nd string?

The chord associated with the 9th fret of the 2nd string is G major.

To understand this, it's important to know that on the guitar, the 2nd string is tuned to B. When you play the 9th fret on this string, you are effectively playing a D note, as each fret represents a half step increase in pitch from the open string. The G major chord is formed by the notes G, B, and D. By playing the 9th fret on the 2nd string (D), you are voicing one of the notes required to create a G major chord.

Moreover, when forming the G major chord in different voicings, the presence of the D note can be critical because it complements the G (which is typically played on the 3rd string) and B notes. Therefore, being aware of the relationship between the notes and the fretboard positions helps in identifying chords effectively.

Understanding the structure of chords and how they fit together on the fretboard enhances your ability to play and create music across various styles, reinforcing the importance of knowing the notes at different positions, such as the 9th fret on the 2nd string for the G major chord.
