What is the note on the 3rd fret of the 6th string?

The note on the 3rd fret of the 6th string is a G. On a standard-tuned guitar, the 6th string (the thickest string) is an E note when played open. Each fret raises the pitch by a half step, so moving to the 1st fret gives you an F, the 2nd fret gives you an F#, and the 3rd fret gives you a G. This is important for understanding the layout of notes on the fretboard, especially how to navigate different positions for playing scales and chords.

Understanding the sequence of notes on the fretboard is essential for any aspiring guitarist, as it helps in playing melodies, improvising, and composing music.
