What note is found at the 1st fret of the E string?

The note found at the 1st fret of the E string is F. On a standard-tuned guitar, the E string, which is the thickest string, is tuned to the note E when played open. Each fret on the guitar represents a half step in pitch. Therefore, if you move up one fret from E, you reach F.

In the context of musical theory, the notes on the E string progress as follows: E (open), F (1st fret), F# (2nd fret), G (3rd fret), and so on. This consistent pattern helps guitarists navigate the fretboard effectively. The first four notes provide a clear representation of how moving up the fretboard raises the pitch.
