Playing in the key of C
C major is the theoretical home key of Western music: all natural notes, no sharps or flats. On guitar, C, Am, Em, F, and G are the working chords. The one wrinkle is F, which as the IV chord requires either a barre or a partial shape — the first "difficult" chord most beginners meet.
