Where can you find the note C on the guitar fretboard?

The note C can be found at the 3rd fret of the 5th string, also known as the A string. This is because the guitar is tuned in a standard EADGBE tuning, where the 5th string (A) is two whole steps up from the open string A; when you press down on the 3rd fret, you raise the pitch to C.

This understanding of the fretboard involves recognizing that each fret increases the pitch by a half step. Therefore, if you start from the open A (5th string), moving up two frets brings you to the note B (2nd fret) and then to C (3rd fret). Knowing the note locations on the fretboard and how they relate to each other is essential for navigating the guitar effectively.
