What is the note at the 10th fret of the E string?

The note at the 10th fret of the E string is a D. When tuning a standard guitar, the E string is the thickest string and is tuned to E in the open position.

To find the note at the 10th fret, we count the half steps starting from E. There are 12 half steps in an octave. The sequence of notes on the E string, starting from the open string, is as follows: E (open), F (1st fret), F# (2nd fret), G (3rd fret), G# (4th fret), A (5th fret), A# (6th fret), B (7th fret), C (8th fret), C# (9th fret), and D (10th fret).

Consequently, reaching the 10th fret lands us on D, which is the pitch found there. This method of counting half steps works for identifying notes across the fretboard and is essential for understanding the layout of notes on each string.
