What note is found on the 7th fret of the 3rd string?

The note found on the 7th fret of the 3rd string is D. To understand why, it's essential to know how the guitar is tuned and the relationship of the fret positions to musical notes.

The 3rd string of a standard-tuned guitar is tuned to G. When you play the open string, you produce a G note. As you move up the fretboard, each fret corresponds to a half-step increase in pitch. Therefore, moving from G on the open string to the 1st fret gives you G# (or Ab), the 2nd fret gives you A, the 3rd fret gives you A#, the 4th fret gives you B, the 5th fret gives you C, the 6th fret results in C#, and finally, the 7th fret results in D.

Understanding the musical alphabet helps solidify this: starting from G and moving through the alphabet (A, B, C, D) gives you D at the 7th fret. This systematic approach to finger positioning and understanding the fretboard is crucial for developing skills on the guitar.
